Tinnitus The Ring You Cant Answer

Ringing, buzzing, hissing, chirping, and whistling will it ever stop For an estimated 50 million Americans with tinnitus, commonly called ringing in the ears, it doesn't. I have lectured to hospital-based tinnitus support groups and heard the word about this incredibly annoying and aggravating condition. The ear noises can be intermittent or continuous, and the loudness also varies. Background noises of daily life often drown out the ringing or buzzing during the day. The worst time seems to be when you're trying to fall asleep in a quiet room. The noises can be so distracting that they interfere with your concentration, work, relationships, and sleeping patterns. For many, the personal distress creates anxiety about going to bed at night. Tinnitus is often associated with hearing loss, but it does not cause the loss, nor does hearing loss cause tinnitus. The cause of tinnitus is obscure.

Vertigo Tinnitus

Vertigo and tinnitus can originate from the upper cervical region (CI, C2 dysfunction) or from an obstruction of the vertebral arteries (secondary to a dens defect or cervical osteophytes). It develops from prolonged cervical back bending (i.e., painting a ceiling), a postural forward head carriage, repeated cervical rotation, or rising from a supine to a sitting position or vice versa. This sensation can also be referred from inner ear (vestibular apparatus in semicircular canals) or temporomandibular joint problems.

Laboratory Tests Audiogram

Any patient known to have or suspected of having a lesion of the lateral skull base or CPA should undergo formal audiomet-ric testing. Standard testing includes air and bone conduction pure tone thresholds, speech reception threshold, and speech discrimination scores. Lesions involving the middle ear typically result in a conductive hearing loss. Audiometrically conductive hearing losses manifest as elevated air conduction thresholds compared with bone conduction threshold (air-bone gap). Sensorineural hearing loss is caused by cochlear or auditory nerve dysfunction and demonstrates air and bone conduction thresholds elevated to the same degree. Lesions that involve the auditory nerve or auditory brainstem nuclei typically result in reduced speech discrimination scores out of proportion to their effect on pure tone thresholds. Any patient found to have an asymmetric sensorineural hearing loss or reporting unilateral tinnitus should be evaluated to exclude lesions of the IAC or CPA...

Auditory Brainstem Response Testing

Auditory brainstem response (ABR) testing uses surface electrodes and a computer to record and average auditory nerve and brainstem potentials in response to click stimuli delivered to the ear. It is useful to screen patients with asymmetric sen-sorineural hearing loss or unilateral tinnitus for retrocochlear lesions. Although ABR is less sensitive than MRI with gado-

New Conceptions of the Brain and of Creativity in the Latter Part of Life

Becoming very old is good - as long as I don't have to take the consequences Whether this is a real quote from Woody Allen or not, many of us probably agree with the sentiment. People seek longevity but want to keep their vital functions intact. For example After a certain age, in the late summers you start to listen eagerly for crickets and you get very relieved when you hear one. Let us then hope that you have not mistaken your tinnitus for the crickets

Normal Continuous Murmurs The Venous Hum

Hum may radiate widely and is often bilateral but is usually more prominent on the right (Fig. 2-11). A loud venous hum, especially in children, may radiate below the clavicles and may be mistaken for a patent ductus arteriosus.41 Abolition of the hum by digital compression prevents this error (Figs. 2-11 and 2-12). Intensity varies from faint to grade 6 6, and occasional patients are subjectively and unpleasantly aware of a loud hum, which is sensed as audible pulsatile tinnitus.7,9,43,60

Central Nervous System Toxicity

CNS symptoms of local anesthetic toxicity usually occur before cardiovascular changes. In humans, the first signs of CNS toxicity include drowsiness progressing to numbness of lips, slurring of speech, agitation, tinnitus, diplopia, fine tremors, and grand mal seizures large doses produce generalized CNS depression (an isoelectric electroencephalogram EEG ). Ironically, there is no evidence that epileptics have a heightened susceptibility to the CNS toxicity of these drugs. In fact, local anesthetics have anticonvulsant action and have been used effectively to stop generalized tonic-clonic seizures. Similarly, local anesthetics have been administered intravenously to produce general anesthesia. Conclusive evidence about how local anesthetics

The neurological neuropsychological behavioural and emotional consequences of TBI

The most common neurological symptoms following TBI include headache, pain, nausea, dizziness or vertigo, unsteadiness or poor coordination, tinnitus, hearing loss, blurred vision, diplopia, convergence insufficiency, increased light and noise sensitivity, and altered sense of taste and smell. TBI has been noted to cause injury to each of the cranial nerves (Russell, 1960) with the concomitant disruption of the various sensory and motor functions of the head. Waddell and Gronwall (1984), for example, have noted significant increases in the sensitivity to light and sound stimuli following mild TBI.

Directed Neurological Examination Sensory Function Of Cranial Nerve V

Evidence of trigeminal motor involvement such as muscle atrophy, spasm, or fasciculations jaw deviation difficulty chewing and hyperacusis may be present. Atrophy of the temporalis is often easy to observe. To assess muscle bulk, the masseter may be pinched between the fingertips and the temporalis muscle should be

Initial Onsite Assessment

The clinician can perform amnesia testing by first asking the athlete simple questions directed toward recent memory and progressing to more involved questions. Asking the athlete what the first thing he or she remembered after the injury will test for length of post-traumatic amnesia. Asking what the play was before the injury or who the opponent was last week will test for retrograde amnesia. Retrograde amnesia is generally associated with a more serious head injury. Questions of orientation (name, date, time, and place) may be asked however, research suggests that orientation questions are not good discriminators between injured and noninjured athletes.29 Facing the athlete away from the field and asking the name of the team being played may be helpful. The athlete should also be asked whether he or she is experiencing any tinnitus, blurred vision, or nausea. The clinician should use a concussion symptom checklist similar to that found in Table 14-1 to facilitate the follow-up...

Other Neurological and Medical Findings

Decreased hearing, increased tinnitus, vestibular impairment (CN VIII) facial numbness (CN V) ataxia incoordination (cerebellum) Decreased hearing, increased tinnitus, vestibular impairment (CN Vlll) Decreased hearing, increased tinnitus, vestibular impairment (cochlea or vestibule involvement) Decreased hearing, increased tinnitus, vestibular impairment Decreased hearing, increased tinnitus, vestibular impairment

Directed Neurological Examination MOTOR

First, the clinician should observe the patient at rest for symmetry and the presence of any involuntary movements (e.g., fasciculations, tics). Signs of facial weakness include flattening of the nasolabial groove, slower blinking, and loss of facial wrinkles. Next, clinicians should check the amount of voluntary motion in each of the five peripheral branches by having the patient perform the following (1) temporal--raise the eyebrows, wrinkle the brow (2) zygomatic--close the eyes gently, and with maximal effort try to keep the eyes closed while the examiner attempts to open them (3) buccal--smile, show teeth, puff out the cheeks (4) mandibular--pout, purse the lips (5) cervical-- sneer. The clinician should determine if the patient exhibits Bell's phenomenon, which is an upward and outward rolling of the globe when eyelid closure is attempted. When there is incomplete closure, this phenomenon protects the cornea by placing it under the upper eyelid and moving it laterally. While...

History And Definitions

Sound consists of sinusoidal waves of air pressure, and hearing is the perception of sound. The understanding of speech depends on the perception of complex, time-varying multifrequency sound. Hearing is possible when the pitch or frequency range of sound is between 20 and 20,000 cycles sec (Hz) and when the sound is appropriately loud. The loudness of sound is measured in decibels. Clinically, such as during audiometry, decibels are expressed as units of hearing level, and are computed by the formula DB 20 log Ptest Pref , where Ptest is the sound pressure level in question and P ref is the sound pressure just barely audible by a group of young adults. Tinnitus is the false perception of a sound, or the perception of a sound that is not normally perceived, such as the pulse. A single sinusoidal tone corresponds to a ringing noise. Complex multifrequency sounds may be perceived as hissing, buzzing, roaring, or even as speech or music.

Syndromes Primarily Involving Vestibular Function

Classic Meniere's disease presents as a quadrad of paroxysmal symptoms, including tinnitus, monaural fullness, fluctuating hearing, and episodic vertigo. This clinical picture is sometimes called the hydrops symptom complex, inferring that the mechanism is related to dilation and rupture of the endolymphatic compartment of the inner ear. The tinnitus is characteristically of two types. Between attacks the tinnitus is characteristically a ringing noise (about 75 percent of the population has ringing tinnitus from time to time). During an attack, the tinnitus becomes a multifrequency noise such as a roar, hiss, or buzz. Patients also generally complain of monaural fullness, a sensation as if the ear were full of water, beginning a day or two before an attack. Hearing is normal at the onset of the condition, but with each attack a low-frequency sensorineural reduction in hearing appears (see FigureJ.2-5 ), and then it usually resolves a day or two later. After many attacks, hearing...

Carotid artery pathology

The carotid arteries can be affected by movement, especially extension (Rivett et al. 1999 Kerry 2005). Carotid pathology often presents with pain, which typically precedes neurological features by hours or weeks (Silbert et al. 1995 Taylor and Kerry 2005). Pain can be related to physical exertion and cervical movement and be felt as neck or facial pain and headache migraine. The headache may be sudden and of a 'thunderclap' nature, and tinnitus may be present. When neurological features start to appear, signs may be facial palsy, ptosis or miotic pupils and other symptoms of Horner's syndrome (Taylor and Kerry 2004, 2005).

General Considerations

To illustrate this concept, consider tinnitus as an example. Tinnitus, the name given to a sensation of sound in one or both ears, commonly accompanies deafness. When tinnitus is present, there is nearly always some degree of hearing loss. Conversely, when there is no appreciable hearing loss, there is rarely tinnitus. However, children who are born deaf do not complain of tinnitus.

Proximal Peripheral Lesions

The glossopharyngeal and vagus nerves pass through the area of the cerebellopontine angle, formed by the junction of the pons, medulla, and cerebellum, before exiting the skull through the jugular foramen. In this area, both nerves may be compromised by an expanding mass lesion, most commonly a schwannoma originating from the vestibular portion of the eighth cranial nerve within the internal auditory canal. The syndrome of a cerebellopontine angle tumor generally begins as tinnitus with hearing loss, and dysequilibrium or frank vertigo, which may be episodic. As the tumor expands, the fifth cranial nerve becomes involved, resulting in ipsilateral facial pain and numbness and loss of the corneal reflex. The cerebellum or cerebellar peduncles may become compressed, producing ataxia. Unilateral impingement upon the vagus nerve causes mild

Secondary Idiopathic Intracranial Hypertension IIH Pseudotumor Cerebri

The disorder tends to affect obese females. Patients report a constant daily headache pain that is diffuse and at least moderate in severity. The headache is aggravated by valsalva-type maneuvers. Other signs and symptoms include papille-dema as well as cranial nerve dysfunction. It is not uncommon for the patient to report visual changes such as blurring or transient visual obscurations (TVOs). Persistently elevated CSF pressures can lead to permanent visual loss. Pulsatile tinnitus and diplopia related to cranial nerve VI palsy are other common complaints.

Temporomandibular Disorder

Temporomandibular joint (TMJ) dysfunction is a fairly common problem. Patients may present with headache which is localized to the preauricular region, mandible, and TMJ region. In addition to frontotemporal headache, patients often complain of otalgia, tinnitus, and dizziness. Clinical history may elicit symptoms of bruxism during sleep and reported jaw locking or popping. Limited jaw opening and tenderness of the masticatory muscles may be noted during examination. TMJ dysfunction leads to myofascial pain contributing to the symptoms of headache. Symptoms are often self-limited but in persistent cases referral to a TMJ specialist may be required.

Traumatic Tympanic Membrane Perforations

Traumatic perforation of the tympanic membrane may result from barotrauma (water skiing diving injuries, blast injuries, blows to side of head), ear canal instrumentation (cotton-tipped applicators, bobby pins, paper clips, cerumen curettes), or otitis media (see earlier discussion). The patient usually complains of acute pain that subsides quickly, associated with bloody otorrhea. Severe vertigo can occur but is transient in most cases. Persistent vertigo suggests inner ear involvement (perilymphatic fistula). Hearing loss and tinnitus are also common.

What do you do now

Neurological symptoms and signs usually follow almost immediately after the onset of the headaches. This finding differs from that usually seen in patients with ICA dissections in the neck, in which initial pain and headache symptoms often precede the brain ischemic symptoms by several days. Patients with extracranial ICA dissections may have headaches, Horner's syndrome, pulsatile tinnitus, and or abnormalities of function of the lower cranial nerves without cerebral ischemia (as in case 5). Patients with intracranial ICA dissection almost invariably develop brain ischemia and cerebral infarcts. Fluctuation of neurological signs during the first 2 weeks after symptom onset is common in patients with intracranial ICA dissections and is explained by either intra-arterial embolism or changes in collateral flow due to hemodynamic factors. Cerebral hypoperfusion is the mechanism of many of these events, in contrast to distal embolism, which is considered to be the most important mechanism...

Clinical Presentation

Signs and symptoms not attributable to the lipoma but secondary to the associated developmental anomalies. Approximately 30 of patients with supratentorial lipomas have a seizure disorder. The seizure disorder is reportedly often severe, is focal or generalized, and has an average onset age of 15 years. Recurrent headaches are a presenting symptom in 25 percent, and . . . 10 to 15 percent have behavioral problems and or mental retardation.23 Other reported signs and symptoms include fainting spells, vomiting, episodic leg weakness, blurred vision, sleepwalking, diencephalic disturbances such as adiposogenital dystrophy and hypothermia, and even transient ischemic attacks.6 Presenting signs and symptoms of patients with infratentorial lipomas may include hydrocephalus, cerebellar ataxia, motor weakness, sleep apnea, and cochleovestibular symptoms such as hearing loss, vertigo, otalgia, trigeminal neuralgia, hemifacial spasm, and tinnitus.6,19,23

General Management Goals

Such as Meniere's disease, treatment directed at the cause may be used, but there is no effective pharmacological management of tinnitus or hearing loss. For tinnitus, an assortment of medications may be empirically tried, including antidepressants, minor tranquilizers, and anticonvulsants. Hearing aids or maskers (devices that generate white noise) are helpful in a few patients.

Outcome and Quality of Life

The postoperative recovery period is highly variable. Based on a recovery recommended for 2 to 3 months, some patients feel eager and fit to take up their profession after as little as 4 to 6 weeks, whereas others continue to suffer from certain sequels, such as head and neck pains, tinnitus induced or worsened by noises and voices, dizziness, and general fatigue, for 6 months or even longer. On close examination, head and neck pain are found to originate from occipital nerve irritation (rare) or preexisting cervical osteochondrosis. Tinnitus is less common in patients with some preserved hearing, whereas it is increased or more irritating to patients with postsurgical deafness. Balance disturbances resulting from the unilateral loss of vestibular nerve

Facial Nerve Schwannomas

The geniculate ganglion level grow into the middle fossa, and those with proximal origin extend into the internal auditory meatus and cerebellopontine angle. Mean age of patients is approximately 40 years.8,10 Facial palsy occurs in most, but not all, cases it can be absent in up to one quarter. Severity of facial weakness ranges from mild paresis to total palsy. It is usually progressive, often proceeded by periods of facial twitching. Sensorineural deafness is usually present. It can be severe or total. However, it is conductive in some cases and rarely the patient can have intact hearing.8 Other symptoms may include vertigo, tinnitus, or ear pain.10 There is a long interval between onset of symptoms and diagnosis.

Vascular Dissection Syndromes

Dissections of arteries develop when there is blood extravasated within the medial or subintimal layers of the arterial wall with resultant compromise of the arterial lumen and development of a pseudoaneurysm. Vascular dissections can be associated with blunt trauma, penetrating trauma, or even trivial trauma. There are a number of associated conditions, including fibromuscular dysplasia, Marfan's syndrome, Ehlers-Danlos type IV syndrome, atherosclerosis, pronounced vessel tortuosity, moyamoya, cystic medial degeneration, pharyngeal infections, alpha -antitrypsin deficiency, and luetic arteritis. However, dissections may occur spontaneously. Cervicocephalic arterial dissections may present with ischemic stroke due to arterial occlusion or secondary embolization. The vessel that is most commonly involved is the extracranial carotid artery between C2 and the base of the skull. The vertebrobasilar system, intracranial carotid, and middle cerebral arteries are less frequently involved. y...

Diagnosis Clinical Presentation

The clinical characteristics of a glomus jugulare tumor depend on its locally invasive behavior, its anatomic extension, the size of the tumor, and whether it secretes neuropeptide hormones. Most commonly, patients have hearing loss and pulsatile tinnitus or dizziness. Hearing loss is usually unilateral and results from invasion of the middle ear. It can be conductive if the ear canal is obstructed or sensorineural if the cochlea or labyrinth is invaded, and is often accompanied by dizziness. Pulsatile tinnitus occurs in association with a highly vascular lesion, which is seen through an otoscope as a pulsatile reddish-blue mass beneath the tympanic membrane. Occasionally, patients develop otorrhea spontaneously or after a biopsy.

TABLE 630 Salicylate Intoxication

Diagnosis of salicylate toxicity should be considered when a history of aspirin use, nausea, and tinnitus are present suspicion should also be raised by clinical findings of unexplained respiratory alkalosis, anion gap metabolic acidosis, or noncardiogenic pulmonary edema

Temporal Bone Syndrome

Conductive hearing loss is the most common manifestation of temporal bone metastasis. It is present in approximately 30 to 40 of symptomatic patients and is almost always the result of dysfunction of the eustachian tube with secondary serous otitis media.9,26,61 Sensorineural hearing loss, if it occurs, is usually due to involvement of the cochlear fibers in the internal auditory meatus.61 Maddox emphasized the triad of symptoms of otalgia, periauricular swelling, and facial nerve paresis as being the most suspect for malignant involvement of the temporal bone.41 He reported an incidence of facial nerve paralysis of 34 in his series. Schuknecht et al also reported a high incidence of facial palsy.63 Saito et al found that only 50 of patients with invasion of the facial canal manifested facial paralysis, although 100 of those who had tumors extending beyond the epineural sheath had complete paralysis.60 Much less common findings are otorrhea, vertigo, tinnitus, or a middle ear...

Neurofibromatosis 2

Molecular Genetics and Clinical Presentation. Neurofibromatosis type 2, also known as bilateral acoustic or central neurofibromatosis, is less common than NF1. NF2 occurs in 1 out of every 40,000 to 100,000 live births.351 Isolated in 1993, the NF2 gene is located on chromosome 22 (22q12.2 locus) and codes for a protein called merlin, or schwannomin.17-18,48 Merlin, or schwannomin, is expressed in fetal brain, kidney, lung, breast, and ovary. Its function is unclear but possibly involved with membrane stabilization of a cytoskeleton-associated protein and intercellular communication. The loss of merlin may lead to the elimination of intercellular contact inhibition, which could lead to tumor development.102 In 10 of cases, NF2 patients become symptomatic before the age of 10. Fifty percent of NF2 patients become symptomatic by age 30 and 90 by age 50.3 NF2 is characterized by schwannomas of the cranial nerve roots, particularly the vestibular portion of the eighth cranial nerve, as...

Acoustic Schwannoma and Trigeminal Neurilemmoma

Clinical Features and Associated Disorders. Acoustic neuromas are considered slow growing, but they grow in a physiologically eloquent area, the cerebellopontine angle, thus leading to subtle complaints that may evolve slowly over many years. Symptoms may progress slowly, although sudden presentations can be seen. Patients usually present with hearing loss (especially sound discrimination), tinnitus, loss of balance, nystagmus, loss of facial sensation, or loss of function of the facial muscles or the muscles of mastication. Pain is uncommon but may sometimes mimic trigeminal neuralgia. Cerebellar findings such as ataxia and gait abnormalities may be noted when extremely large tumors have extended into the cerebellum. In patients with trigeminal pain multiple sclerosis may be diagnosed initially only with further hearing loss and a lack of involvement of other areas of the nervous system will re-evaluation be conducted. Meningiomas are occasionally confused with neuromas. Rarely,...

Health status and quality of life as PRO outcomes

For example, authors of a Cochrane review of cognitive behavioural therapy (CBT) for tinnitus included quality of life as an outcome (Martinez-Devesa 2007). Quality of life was assessed in four trials using the Tinnitus Handicap Questionnaire, in one trial the Tinnitus Questionnaire, and in one trial the Tinnitus Reaction Questionnaire. The original sources are cited in the review. Citations to articles on the psychometric properties are also available in MEDLINE for all three instruments and could easily be identified with a search using the Google search engine. Information on the items and the concepts measured are contained in these articles, and review authors were able to compare the content of the instruments.

Glomus Jugulare Carotid Body Tumors

Glomus jugulare tumors arise from the paraganglionic tissue surrounding the jugular vein in the area of the middle ear. These tumors most often present late in life, in the sixth or seventh decade, and may have a genetic predisposition. They are locally invasive and highly vascular. Although presenting symptoms include complaints similar to those typical of acoustic neuromas, with tinnitus or hearing loss, the key differentiating features of these tumors are pain and the presence of loud pulsations in the ear. Occasionally, blood may drain from the ear. On examination, the patient may have tumor visible in the ear canal and, with larger lesions, evidence of cranial nerve or cerebellar dysfunction. The differential diagnosis includes neuromas, cholesteatomas, meningiomas, vascular malformations, or metastatic disease.

Labyrinthitis Vestibular Abnormalities and Menieres Disease

Patients with labyrinthitis usually experience hearing changes, whereas those with vestibular neuronitis do not. A viral infection is the usual cause in younger patients while infarction becomes more likely in the older adult. Older-adult patients may recover more slowly and experience feelings of imbalance for several months. Treatment during the symptomatic period may include vestibular rehab exercises and pharmacologic agents such as meclizine, promethazine, or low-dose benzodiazepine (e.g., lorazepam). Meniere's disease should be suspected when an older adult reports recurrent episodes of vertigo, tinnitus, gradual development of low-frequency hearing loss, and in some cases ear fullness before onset of vertigo.

Turn On Your Acu Points Shut Off the Ringer

Using the tools and techniques of Oriental Medicine, you and your acu-pro can effectively manage tinnitus so that you will hardly notice the noise inside your head. While I've not been successful in every case, the number of people who have been helped is growing. The two most common oriental diagnoses of tinnitus that I see are rising liver and gallbladder fire, and kidney deficiency. Rising liver and gallbladder fire is characterized by sudden onset of a loud noise, emotional stress, headache, irritability, a bitter taste in the mouth, constipation, dizziness, reddish face, and thirst. Deficient kidney tinnitus comes on gradually with low, intermittent sounds, poor memory, blurred vision, sore back and knees, and reduced sexual desire or performance. Sally was 68, widowed, and retired. She was looking forward to a peaceful life of helping her daughter with the new grandchildren and volunteering in her community. She'd had tinnitus for almost 20 years, but the ringing had been...

Neurofibromatosis Type

Diagnostic criteria for NF2 devised at the 1987 NIH Consensus Development Conference on Neurofibromatosis37 were subsequently revised by the National Neurofibromatosis Foundation (NNFF) Clinical Care Advisory Board (Table 108-3). Patients with NF2 clinically may report a variety of difficulties. The majority of these are neurologic, including hearing impairment, tinnitus, imbalance, weakness, seizures, numbness or paresthesias, or impaired vision. Approximately 11 are identified while asymptomatic as a result of screening within affected families. Only 10 of patients become symptomatic before age 10.15 In addition, new signs and symptoms may develop with increasing age, and therefore the evaluation of an NF2 patient must involve long-term, continued serial assessments. Aside from these ocular findings, the majority of features of NF2 involve the nervous system. As mentioned earlier, the hallmark of this disorder is bilateral vestibular schwannomas (Figure 108-5). Patients with NF2...

Sedative Hypnotics including Benzodiazepines

Withdrawal signs and symptoms from sedative-hypnotics include tachycardia, hypertension, fever, agitation, anxiety, hallucinations, insomnia, irritability, nightmares, sensory disturbances, tremor, tinnitus, anorexia, diarrhea, nausea, seizures, delirium, and death. Most sedative-hypnotic withdrawal is managed by either simple, slow, fixed-dose taper or substitution and taper. A simple taper involves decreasing the dose by no more than 10 every 1 to 2 weeks until the starting dose has been 75 decreased, then by 5 every 2 to 4 weeks for the last 25 until the taper is completed. Substitution and taper involves substituting a long-acting benzodiazepine (e.g., clonazepam) or phenobarbital for a shorter-acting drug and tapering as above. Conversion tables are available to calculate an approximate equivalent dose, and the dose is titrated over several days to a week, to achieve good relief of withdrawal symptoms before tapering is begun of the substitute, as with the simple taper method....

Low Pressure Headache

Clinical Features and Associated Disorders. Low pressure headache is the most common complication of lumbar puncture, occurring in 15 to 30 percent of patients. Onset varies from 15 minutes to 4 days following lumbar puncture, but it can take as long as 12 days. If it is left untreated, the headache can last 2 to 14 days (most commonly 4 to 8 days) or even months.y The headache of intracranial hypotension may be frontal, occipital, or diffuse. It is accentuated by the erect position and relieved with recumbency. The pain is severe, dull, or throbbing in nature, and usually not relieved with analgesics. It is aggravated by head-shaking, coughing, straining, or sneezing, and jugular compression. The more severe the headache, the more frequently it is associated with dizziness, nausea, vomiting, and tinnitus, and the longer the patient is upright, the longer it takes the headache to subside with recumbency. Physical examination is usually normal

Clicking and Popping Rocabado M

The muscles of mastication are innervated by the same nerves as the tensor tympani and tensor palatini. This may explain the ear symptoms caused by temporomandibular joint dysfunction. If the tensor muscles go into spasm, it may lead to tinnitus, hearing problems, and a sensation of ear stuffiness. There is also a reflex arc with sympathetic nerve fibers. The fibers originate in the temporomandibular joint and end up in the cochlea. This could also explain the dizziness and tinnitus.

Migraine with Aura Classic Migraine

A variety of migraine clinical subtypes have been described. Basilar migraine, previously called basilar artery migraine, was originally believed to be a disorder of adolescent girls, and although there is a clear female predominance, it is now known to affect all age groups. Severe headache is preceded by a visual aura, then brain stem signs of ataxia, vertigo, tinnitus, diplopia, nausea and vomiting, nystagmus, dysarthria, bilateral paresthesia, and a change in level of consciousness and cognition. Confusional migraine, which occurs more commonly in boys than in girls, is characterized by headache accompanied by inattention, distractibility, and difficulty maintaining speech and other motor activities. Spells of basilar and confusional migraine can present a confusing picture and should be considered in patients with paroxysmal brain stem disturbances. , y

The anterior inferior cerebellar artery AICA

The classic AICA syndrome includes vertigo with vomiting and nystagmus (vestibular nuclei, vestibular nerve or labyrinthine artery), ipsilateral deafness with tinnitus (cochlear nerve or cochlear artery), ipsilateral peripheral-type facial palsy (facial nucleus or fascicle of VII), ipsilateral facial hypesthesia (trigeminal nuclei or fascicle), ipsilateral Horner's syndrome (descending sympathetic tract), ipsilateral ataxia, dysar-thria (middle cerebellar peduncle and cerebellum) and contralateral thermoalgesic sensory deficit (spi-nothalamic tract). It is frequently misdiagnosed as Wallenberg syndrome, but the main clinical distinctions are the hearing loss and the peripheral-type facial palsy. Occasionally, horizontal ipsilateral gaze palsy or dysphagia are also present. More rarely, AICA territory stroke can present as an isolated vertigo or isolated cerebellar syndrome.

Table 556 Peripheral Neurotoxicity Of Antibiotics

The toxicity of all aminoglycosides is similar--mainly ototoxicity and neuromuscular blockade (llTable.lll55z7.). Acute ototoxicity is based on calcium antagonism and blockade of ion channels, and chronic mechanisms are related to tissue-specific toxicity of a noxious metabolite. The frequency of ototoxicity ranges from 2 to 4 percent in retrospective studies and up to 25 percent in studies with specialized testing. The incidence and severity of damage appear to increase with patient age, total drug dose, and concomitant use of other ototoxic drugs. y Auditory toxicity is more common with the use of amikacin and kanamycin, whereas vestibular toxicity predominates following gentamicin and streptomycin therapy. Tobramycin is associated equally with vestibular and auditory damage. Cochlear toxicity is more often silent, as the hearing loss first affects the high frequencies (greater than 4000 Hz) before involving the speech frequencies. Cochlear toxicity presents clinically as deafness,...

Ischemic strokes and transient ischemic attacks caused by low cerebral flow posterior circulation

Vertebral Artery Tortuosity After Fall

Rotational vertebral artery occlusion (RVAO) is caused by mechanical compression of vertebral arteries during head rotation. The vertebral artery is usually compressed at the atlantoaxial C1 -C2 level. Tendinous insertions, osteophytes or degenerative changes resulting from cervical spondylosis may be the cause of compression. Most RVAO patients exhibit an ipsilateral stenosis or vessel malformation (e.g. hypoplasia) and a contralateral dominant vertebral artery. With ispilateral head rotation, the (contralateral) dominant vertebral artery is compressed. The leading symptom is vertigo, followed by tinnitus. Video-oculography showed that RVAO is associated with a mixed downbeat torsional and horizontal beating nystagmus which may spontaneously reverse direction 3 . The labyrinth is predominantly supplied by the internal auditory artery, which is usually a branch of the anterior inferior cerebellar artery (AICA). As AICA usually takes off the basilar artery at its lower portion, reduced...

Treatment of Cervically Mediated Dizziness

Further understanding of cervicogenic dizziness comes from treating dizzy patients without headache and cervicogenic headache patients without dizziness. The disorder is suggested by not meeting IHS criteria for either cervicogenic headache or migraine. A spectrum of improvement was seen with greater occipital nerve injections for patients with dizziness and headache, including relief of symptoms of ear discomfort, tinnitus, and neck pain, along with improvements in the headache and dizziness.

If the facial weakness is secondary to Ramsay Hunt syndrome, treatment is similar to that of Bell's palsy, but the clinical course and expected outcomes differ. This syndrome is caused by herpes zoster (rather than herpes simplex) involvement of the facial (geniculate), vestibulocochlear, and or trigeminal ganglia. The infection causes pain and eventually vesicular eruptions around the auricle and external ear canal. Vesicles may appear only in the pharynx or hard palate in some cases. Facial weakness and at times dense paralysis are common. Hearing loss, tinnitus, and persistent vertigo also occur in 20 to 30 of patients (Adour, 1994). As with Bell's palsy, prompt initiation of oral steroids and acyclovir should begin when the diagnosis is suspected. This therapy can lessen vertigo and improve recovery of facial

Hyperviscosity and low flow

Cerebral blood flow is diminished with high hematocrit as found in polycythemia vera. Symptoms are often unspecific, such as headache, dizziness or vertigo, paresthesias, blurred vision or tinnitus. Low flow and or increased coagulability may be the cause of focal brain ischemia. Different ischemic patterns have been described, such as lacunar infarction, boundary infarction, Binswanger's disease or large artery (territorial) infarction. In sickle-cell anemia, deformability of red cells is decreased. This may cause damage in the microcirculation, particularly in the boundary zones between major arterial territories. But large-artery occlusive disease, occasionally with the development of moyamoya, was also found. Plasma hyperviscosity syndrome is a clinical entity with mucous membrane bleeding, blurred vision, visual loss, lethargy, headache, dizziness, vertigo, tinnitus, paresthesias, and occasionally seizures. Abnormal changes of blood plasma lead to a hyperviscous state and...

Functional anatomy

Deafness in one ear, although this is rare due to significant cross midline communication in the brainstem. Auditory symptoms are associated with brainstem strokes and may include hearing loss (if bilateral stroke), phantom auditory perceptions (tinnitus hallucinations) and increased sensitivity to sound (Hausler and Levine, 2000). Lesions to the auditory cortex in the temporal lobe (cortical deafness) may mean that although the patient is unable to consciously hear sound, they may be able to reflexively respond to sound thus 'appear' to hear Lesions to adjacent association areas (Wernicke's area) result in patients being unable to comprehend the meaning of sounds or words, known as receptive aphasia or agnosias to particular sounds.

Paragangliomas

Paragangliomas (glomus tumors, chemodectomas) are benign, vascular, slow-growing tumors arising from paraganglionic glomic tissue of neuroectodermal origin. These tumors are found in adults and have a predilection for females.3 The four most common sites are the jugular foramen (glomus jugulare), cochlear promontory of the middle ear (glomus tympanicum), carotid body, and vagus nerve (glomus vagale). Presenting clinical symptoms often include pulsatile tinnitus other symptoms are caused by local mass effect and depend on tumor location.26 On MRI, these tumors exhibit an internal salt-and pepper appearance because of the abundant tumor vessels. Glomus jugulare tumors often erode the jugular foramen, a process best seen on CT scanning.31

Schwannomas

Schwannomas (neuromas) are benign tumors arising from the cranial nerve sheaths, which are formed of Schwann cells. Ninety percent occur in the cerebellopontine angle,24,39 and they are usually solitary. The so-called acoustic schwannoma is by far the most common tumor of this type bilateral acoustic schwannomas are the hallmark of the central form of neurofibromatosis 2 (NF2).5,28 The trigeminal nerve is the next most common site of origin.24 Generally, schwannomas are firm, encapsulated tumors that may contain cysts. As the tumor grows, it may become lobulated, increase in vascularity,29 or develop arachnoid adhesions that may result in arachnoid cysts. Clinical presentation depends on the size and site of origin of the tumor. Acoustic schwannomas initially present with tinnitus and progressive neurosensory hearing loss. Tumor enlargement into the cerebellopontine angle can produce ataxia or compression of the brainstem or exiting cranial nerves.

Class lb

Mexiletine is a longer-acting, orally effective lidocaine analogue, which is well absorbed orally, with peak plasma concentrations after 2 h and an elimination half-life of 10-15 h. It undergoes hepatic metabolism and is excreted via the kidneys. Hypotension, bradycardia and heart block may occur after i.v. administration. Most frequent adverse effects involve the CNS and include tremors, nystagmus, confusion, speech disturbances, tinnitus, paraesthesiae and convulsions. Gastrointestinal effects are also common during oral treatment.

Mild Concussion

The mild concussion, which is the most frequently occurring (approximately 85 ), is the most difficult head injury to recognize and diagnose.15-17 The force of impact causes a transient aberration in the electrophysiology of the brain substance, creating an alteration in mental status. Although mild concussion involves no LOC, the athlete may experience impaired cognitive function, especially in remembering recent events (post-traumatic amnesia) and in assimilating and interpreting new information.6,17-19 Dizziness and tinnitus (ringing in the ears) may also occur, but there is rarely a gross loss of coordination that can be detected with a Romberg test. The clinician should never underestimate the presence of a headache, which presents to some degree with nearly all concussions.15 The intensity and duration of the headache can be an indication of whether the injury is improving or worsening with time.

Severe Concussion

It is not difficult to recognize a severe concussion, as these injuries present with signs and symptoms lasting significantly longer than mild and moderate concussions. The athlete will often experience more signs and symptoms than described in the previous two levels, and blurred vision, nausea, and tinnitus are more likely to be present. Most experts agree that a concussion resulting in prolonged LOC should be classified as a severe concussion. Some authors1,9 classify brief LOC (including momentary blackout) as a severe concussion instead of the more widely accepted moderate classification. The severe concussion may also involve post-traumatic amnesia lasting longer than 24 hours, as well as some retrograde amnesia (memory loss of events occurring prior to injury). In addition, neuromuscular coordination is markedly compromised, with severe mental confusion, tinnitus, and dizziness. Again, despite the emphasis often placed on LOC and amnesia, it is important to consider the...

Clinical History

Associated features A history of other neurological disorders or any evidence of neurological symptoms (e.g., headache, hemiplegia, loss of sensation, cranial nerve dysfunction, changes in balance or tendency to veer toward the same side) should be elicited, while seeking evidence of central pathology. In addition, it is imperative to check for signs and symptoms referable to the ear (e.g., otalgia, otorrhea, hypersensitivity to sound, hearing loss, tinnitus, or vertigo). To help localize the site of lesion, one should note whether other functions of CN VII are involved in patients with facial weakness (e.g., change in tearing, change in taste, reduced salivation). A history of vesicles in the ear, especially if there are CN VIII symptoms, suggests Ramsay Hunt syndrome. A history of tick bites and rash (erythema chronicum migrans) suggests Lyme disease. Facial swelling and fissuring of the tongue is seen with Melkersson-Rosenthal syndrome.

Syndromes of Paresis

Pathology involving CN VII in this region often involves CN VIII (sensorineural hearing loss, tinnitus, vestibular weakness). Depending on the size and exact location of the lesion, other structures in this region can be affected, like the cerebellum (ataxia, incoordination) and CN V (reduced facial sensation, impaired corneal reflex). Common etiologies include acoustic neuromas and meningiomas. Facial Canal Syndrome. The location of the lesion determines the actual deficit. In the labyrinthine segment, facial palsy is seen with ipsilateral hearing loss and vestibular weakness. In addition, hyperacusis and a decrease in tearing and in salivation with loss of taste can be detected. With lesions of the tympanic segment that are distal to the greater superficial petrosal nerve, all of the above may be found, except that lacrimation is intact. If the mastoid segment is involved, as with tympanic lesions, hearing and balance may be affected, and lacrimation...

Perilymph Fistula

Rapid changes in air pressure (barotrauma), otologic surgery, violent nose blowing or sneezing, head trauma, or chronic ear disease may cause leakage of perilymph fluid from the inner ear into the middle ear and result in episodes of vertigo. Associated signs and symptoms are variable but can include a sudden pop in the ear followed by hearing loss, vertigo, and sometimes tinnitus. Diagnosis can be determined by a fistula test, in which negative and positive pressures are applied to the tympanic membrane using pneumatic otoscopy, causing nystagmus and vertigo.

Cerumen

Cerumen impaction is the symptomatic accumulation of cerumen in the external canal or an accumulation that prevents a needed assessment of the ear. Complete occlusion is not necessary. Symptoms may include hearing loss, tinnitus, pruritus, fullness, otalgia, cough, odor, and dizziness. Impac-tion often results from instrumentation with cotton-tipped applicators, which should be discouraged. Elderly patients with changes to external canal epithelium, patients with external canal abnormalities (e.g., osteomas, exostoses, stenosis), and users of hearing aids and earplugs are also at risk for impaction. Excessive cerumen production as a primary problem is relatively rare.

Acoustic Neuroma

The primary symptoms of vestibular schwannoma are asymmetric hearing loss (sensorineural) and tinnitus. The hearing loss is usually gradual in onset and progressive but can occur suddenly. Disequilibrium is not usually the chief complaint on presentation, but patients often admit to mild unsteadiness. Larger tumors can cause dysesthesia around the ear or facial weakness, or both. If the neuroma is diagnosed late, patients can manifest cerebellar symptoms and symptoms of mass effect and obstructing hydrocephalus.

Procedure

It requires considerable skill on the part of the operator to maintain a calm and pleasant environment. As the dose increases, the patient will report sensory changes including paraesthesia in the extremities, tinnitus and a general feeling of warmth. This is a result of peripheral vasodilation and can be seen in the flushing of the facial features. As the sedation level increases, patients often begin to report visual disturbance and a feeling of remoteness or disassociation. This is the stage

Josef P Rauschecker

This chapter covers plasticity in the central auditory system, most notably in the auditory cortex, from a variety of viewpoints. Neuroanatomical and neuro-physiological studies in animals as well as behavioral and functional imaging studies in humans will be considered. Plasticity in the auditory system will be compared to plasticity in other sensory systems, and the reorganization of the central auditory system during early blindness and deafness will be discussed. The findings from research in auditory cortical plasticity have important implications for the design of auditory prostheses, such as cochlear implants, in the deaf, and visual prostheses in the blind using nonvisual modalities. They also further the understanding and treatment of common ailments, including hearing loss and tinnitus in an aging population as well as the effects of otitis media in young children. Auditory cortex plays a crucial role in higher perceptual and cognitive functions, including those of speech...

Cn Vii Branches

V Injury to CN VII, after it exits the brainstem, results in paralysis of the facial muscles (Bell's palsy) on the ipsi-lateral side. Fracture of the temporal bone can result in the abnormalities just described, plus increased sensitivity to noise (hyperacusis) due to the lack of innervation to the stapedius muscle, dry mouth due to a decrease in salivation, dry corneas due to the lack of lacrimal gland activity, and a loss of taste on the anterior two-thirds of the tongue. It should be noted that a brainstem injury to CN VII results in paralysis of the contralateral facial muscles below the eye.

Hemifacial Spasm

Clinically, symptoms begin in the periorbital region and spread to the ipsilateral facial muscles during the next few months. Spasm occurs spontaneously, is almost always unilateral, and is exacerbated by voluntary facial movements such as lip pursing, stress, fatigue, anxiety, or a change in head position. Ihe movements often persist during sleep. Stapedius muscle contraction frequently accompanies contraction of the muscles of facial expression and may produce ipsilateral tinnitus. y

Hypocapnia

Hyperventilation is defined as breathing in excess of metabolic demands and, therefore, is purely a respiratory disturbance. It produces hypocapnia, respiratory alkalosis, cerebral vasoconstriction (which, in turn, reduces the CBF), a reduction in the availability of O 2 peripherally (through shifts of the O 2 dissociation curve), a reduction in the level of ionized serum Ca, and when sustained, significant hypophosphatemia. y Thus, neurological features are frequent, and patients with hyperventilation disorders are frequently referred to neurologists. Symptoms associated with hyperventilation vary widely and include lightheadedness, acral and perioral paresthesias (which may be painful), syncope and, less commonly, carpopedal spasms, muscle cramps, blurred vision, headache, dyspnea, and chest pain. y , 55 Other reported symptoms include sweating of the hands, cold extremities, giddiness, ataxia, tremor, tinnitus, hallucinations, epigastric pain, a bloated feeling, vomiting, and...

Dizziness

Meniere's disease can result in protracted attacks of severe vertigo associated with vomiting. Many patients with Meniere's disease also have the symptoms of tinnitus and hearing loss. During the attack, the patient is unsteady, with horizontal nystagmus directed away from the affected ear. Certain drugs (such as gentamicin) are associated with changes in the labyrinth of the ear and can cause vertigo and deafness.

Conclusion

Intensive patient interview about the presence of headache, tinnitus, drug abuse, family history careful skin examination careful fundoscopic examination and in selected patients serology for syphilis and HIV, electrophoresis of proteins, antiphospholipid antibodies and testing for thrombophilia. Causes

Biological Dentistry

Examples of illnesses and problems that biological dentists aim to cure, in addition to cancer, include tinnitus (a ringing noise in the ear), vertigo, epilepsy, hearing loss, eye problems, sinusitis, joint pain, kidney problems, digestive disorders and heart disease. Root-canal procedures are said to be the cause of serious Illnesses, and dental fillings are believed to release mercury, tin, copper, silver and zinc into the body, where they break up into charged atoms and create the illnesses and allergies. Therefore, biological dentists recommend replacing all metal fillings with natural, nontoxic, biocompatible material. Another example of these unfounded beliefs in that electricity is created by dental fillings, which may cause lack of concentration, memory loss, insomnia, psychological problems, tinnitus, vertigo, epilepsy, hearing loss, and eye disorders.

Migraine

Other migraine types include basilar-type migraine, retinal migraine, status migrainosus, and migrainous infarction. Basilar-type migraine aura symptoms are referable to the brainstem or bilateral hemispheres, including dysarthria, vertigo, tinnitus, diplopia, and bilateral paresthesias. Reversible monocular, positive or negative visual disturbances associated with migraine are characteristic of retinal migraine. A diagnosis of status migrainosus requires an ongoing migraine of at least 72 hours in duration. Neuroimaging evidence of a cerebral infarct associated with a migraine is indicative of migrainous infarction.

Neurofibroma

Clinical Features and Associated Disorders. In NFII the bilateral acoustic neuromas usually become evident at the same time. Presenting complaints include tinnitus or hearing loss. Most patients have a first-degree relative who is similarly afflicted. Patients with NFII are also at risk of meningioma, gliomas, ependymoma, and schwannoma. Symptoms are the same as those discussed under the respective tumors. Patients with NFII should be closely observed for any changes in auditory function, including hearing loss and tinnitus. During the neurological examination, particular attention should be focused on other cranial nerve abnormalities. Physicians should monitor the patient for any evidence of vertigo or difficulty with balance, possibly with yearly brain stem auditory evoked potentials. Formal audiometry on a yearly basis is a reasonable alternative as well yearly MRI scanning is not generally indicated but may be repeated serially to allow a gauge of tumor enlargement.

Antimalarials

Chloroquine, once considered too toxic for humans, has been the antimalarial of choice for 40 years. Although a range of serious CNS effects has been documented during chloroquine therapy, the incidence is unclear. y Abnormal involuntary movements including torticollis, blepharospasm, and dystonic tongue protrusion have been reported during chloroquine therapy, especially in patients younger than 30 years of age. i Headache, nausea, and tinnitus with progressive hearing loss, optic nerve dysfunction, seizures, psychosis, mania, and myasthenic syndrome have also been reported.

Labyrinthitis

As with vestibular neuronitis, labyrinthitis causes sudden and severe vertigo. In contrast to vestibular neuronitis, the patient also has tinnitus and hearing loss. The hearing loss is sensorineural, is often severe, and can be permanent. Laby-rinthitis is caused by inflammation within the inner ear. The cause is most often a viral infection but can be bacterial. Bacterial labyrinthitis usually results from extension of a bacterial otitis media into the inner ear. A noninfectious serous labyrinthitis can also occur after an episode of acute otitis media. Other, less common causes include treponemal infections (syphilis) and rickettsial infection (Lyme disease). Symptomatic treatment of labyrinthitis is similar to that for vestibular neuronitis. Antibiotics are recommended if a bacterial cause is suspected. As with acute otitis media, bacterial labyrinthitis can, in rare cases, lead to meningitis. Few other conditions cause the constellation of hearing loss, tinnitus, and vertigo, but...

Menieres Disease

Meniere's disease is characterized by episodic severe vertigo lasting hours, with associated symptoms of unilateral roaring tinnitus, fluctuating low-frequency hearing loss, and aural fullness. Typical onset is in the fifth decade of life. The cause is uncertain but is speculated to result from allergic, infectious, or autoimmune injury. The histopathologic finding includes endolymphatic hydrops, which is thought to be caused by either overproduction or underresorption of endo-lymph in the inner ear.

Objective

Heard by the patient and the examiner. In most cases, tinnitus is secondary to bilateral sensorineural hearing loss and requires no further evaluation. In rare cases, tinnitus can be a symptom of a vascular abnormality (aneurysm or arteriovenous malformation), hypermetabolic state, or intracranial mass that, if not evaluated, could result in delayed treatment. Middle ear and rarely external ear pathology can also cause tinnitus, as can numerous medications (Box 19-2). The patient's medications should be reviewed. Evaluation of tinnitus begins with a complete medical history, including duration of symptoms, possible inciting event (e.g., acoustic trauma), and accompanying symptoms (e.g., vertigo, hearing loss, headache, vision changes). Specific questions regarding the tinnitus are critical Is it unilateral or bilateral What is the quality of the tinnitus (pitch, volume) Does it sound like a heartbeat or rushing blood Does it change A complete ENT evaluation should be performed, and...
