Standard auditory brainstem responses ABR generally reflect the status of the puretone thresholds. To me, the ideal candidate is one early in the course of the disease with frequent and severe vertigo attacks, normal ENG function, and fluctuation of hearing.
Rather, they attest to the limited symptom set associated with the vestibular labyrinth and its central connections. Stahle et al, Based on the estimate from Rochester Wladislavosky et al,about 46, new cases develop annually in the United States.
These have been very grateful patients in my experience. It is used less often now because agents that do not exhibit tachyphylaxis are available. Compensation for the loss of vestibular function is a df for older patients.
In general, younger people with intractable vertigo in my practice opt for nerve section because hearing preservation and vertigo control are predictable.
Thus, there is considerable art in the medical management of people with MD. The reader is encouraged to review these philosophic approaches. Most candidates have lost considerable hearing and balance function prior to surgery so the subsequent removal of remaining function is generally well tolerated.
In December the U. Older patients, particularly those with nonserviceable hearing, tend to opt for labyrinthectomy because of safety and simplicity. Furstenberg and Lashmet recommended the low salt diet and ammonium chloride. The Meniett device offers symptom control with little risk for those who have failed medical therapy.
Labyrinthectomy is effective in controlling vertigo and is useful for older people with nonserviceable hearing. Otolaryngol Head Neck Surg Hrobjartsson A, Gotzsche P.

However, since nystagmus is named according to its quick component, the direction of irritative nystagmus is toward the affected ear. Otolaryngol Clin North Am 8: These cases may be considered as the exception rather the rule for typical MD and, possibly, the manifestation of a different disorder. Torok suggested that most forms of therapy have only a placebo effect and that the response to therapy simply manifests the natural history of the disease. Qvortrup and colleagues Qvortrup et fisoopatologia, noted fisiopatklogia features of the sac that resembled endocrine organelles.

For the three months prior to operation, the average monthly vertigo score was 30 for both groups. Otol Neurotol 26 4: First, the mechanism of its effect is incompletely understood. This was a bold study with careful controls to minimize bias. Am J Otol 9: Morrison et al, Repeated audiograms showing fluctuation or a positive glycerol test are held to be evidence of cochlear hydrops. Given that the procedure is safe, is done as an outpatient, and is rarely associated with hearing loss or vestibular loss, it remains a valuable choice for some patients.
It is not known whether hydrops is the cause of the symptoms or simply a side effect of the disorder. Fortunately, fully digital aids, which limit overstimulation, are reasonably effective in ameliorating the effects of loudness recruitment while compensating for the elevated thresholds of the affected ear.

Salt A, DeMott J. After the surgery, the average monthly score over 12 months fell to 3 per month for the active surgery group and to 9 per month for the sham surgery group. Ann Otol Rhinol Laryngol A report of cases.
We concluded that the Meniett device is a safe and effective treatment for people with classical MD who had failed conservative medical therapy. The pros and cons of this approach have been reviewed Smith and Pillsbury Static pressure changes transmitted to the inner ear fluids equalize within seconds Densert et al,but intermittent pressure pulses reduce experimental hydrops Densert et al,
