In 1861, the French physician Prosper Meniere described a condition which now bears his name. Causes An acute attack of Meniere’s disease is generally believed to result from fluctuating pressure of the fluid within the inner ear. Meniere’s disease can cause hair cell death, as well as mechanical changes to the ear. Hair Cell Death The periodic admixture of perilymph and endolymph often kills hair cells in the inner ear.
Mechanical Changes Mechanical disruption of the inner ear is also likely, with dilation of the utricle and saccule of the ear being a well known pathological finding.
There is presently no evidence that Meniere’s disease kills the cochleovestibular nerve (Kitamura et al, 1997). Hearing tests often begin with showing a fluctuating low-frequency sensorineural hearing loss. Treatment At the present time there is no cure for Meniere’s disease, but there are ways to manage the condition and help you control symptoms.
Have you had any of the following imaging studies done as they pertain to your requested appointment?
Meniere’s disease is a disorder of the inner ear that causes episodes of vertigo, ringing in the ears (tinnitus), a feeling of fullness or pressure in the ear, and fluctuating hearing loss.
These are called otolithic crisis of Tumarkin, from the original description of Tumarkin (1936). There is some controversy about this statistic however; some authors suggest that the prevalence of bilaterality is as low as 17% (Silverstein, 1992). A low-frequency sensorineural pattern is commonly found initially, but as time goes on, it usually changes into either a flat loss or a peaked pattern (click here for more information about hearing testing). This is a gradual process over years, but frequently resulting in unilateral functional deafness.


The saccule may dilate so that, in later stages, it is adherent to the underside of the stapes footplate.
Questions related to surgery scheduling, cancellation, rescheduling or pre-operative exams must be conducted via telephone or in-person with our surgical scheduling staff during normal business hours. In Figure 1, the area of the ear affected is the entire labyrinth, which includes both the semicircular canals and the cochlea. A Meniere’s episode generally involves severe vertigo (spinning), imbalance, nausea and vomiting. These are attributed to sudden mechanical deformation of the otolith organs (utricle and saccule), causing a sudden activation of vestibular reflexes. Between the acute attacks, most people are free of symptoms or note mild imbalance and tinnitus. We suspect that this lower statistic is due to a lower duration of follow-up and that the 50% figure is more likely to be correct.
It is most often attributed to viral infections of the inner ear, head injury, a hereditary predisposition, and allergy. This mechanical disruption and distortion of normal inner ear structures may result in the gradual onset of a chronic unsteadiness, even when patients are not having attacks. The differential diagnosis is broad and includes perilymph fistula, recurrent labyrinthitis, migraine, congenital ear malformations of many kinds, syphilis, tumors, Multiple Sclerosis, etc. Patients suddenly feel that they are tilted or falling (although they may be straight), and bring about much of the rapid repositioning themselves.
Other possibilities, however, are selection bias and different patterns of the disease in different countries.
Vestibular (motion sensing) hair cells seem more resilient but there is also a slow decline in the caloric response in the diseased ear over roughly 15 years (Stahle et al, 1991). The periodic dilation and shrinkage of the utricle is also a reasonable explanation for periodic attacks of another inner ear disorder, BPPV.


The process of diagnosis usually includes hearing testing (audiometry), an ENG test, several blood tests (ANA, FTA), and an MRI scan of the head. Following a severe attack, most people find that they are exhausted and must sleep for several hours. This is a very disabling symptom as it occurs without warning and can result in severe injury. Silverstein suggested that 75% of persons destined to become bilateral do so within five years.
One way for this to happen is when the drainage system, called the endolymphatic duct or sac is blocked. Finally, it also seems likely that there may be a rupture of the suspensory system for the membranous labyrinth.
Often destructive treatment (for example labyrinthectomy or vestibular nerve section) is the only way to manage this problem. In some cases, the endolymphatic duct may be obstructed by scar tissue, or may be narrow from birth. This might create some mechanical instability of the utricle and saccule and consequently some chronic unsteadiness.
The majority of people with Meniere’s disease are over 40 years of age, with equal distribution between males and females.
