Testing for Meniere's disease

Timothy C. Hain, MD Page last modified: August 7, 2017

Main meniere's page is here:

Patients sometimes ask why they need to have inner ear testing with Meniere's disease.

In our clinical otoneurology practice in Chicago, we usually see at least one new patient with Meniere's disease every day. As of 2016, we had more than 500 patients in our clinical database.

A patient who fits clinical criteria for Meniere's, but who is without any previous testing, is usually asked to undergo the following procedures

Some practices (not ours) also do "dehydration tests" using the glycerol, isorbide or furosemide to rule in Meniere's with a variety of outcome variables. (Lee et al, 2016) Seo et al (2017) reported using the "furosemide loading test" with VEMP, and reported "Normalized amplitude of VEMP, using a tone burst sound at 250, 500, 700, 1000, 1500 and 2000 Hz, was measured before and after furosemide administration in the two groups. Improvement ratio (IR) of amplitude was calculated at each frequency." This to us seems like a large # of VEMP tests 6 per ear, before and after a strong diuretic (which might have consequences as well).

They sometimes say -- I am already dizzy - -why should I have tests done that could make me dizzier (briefly of course). Patients are also often concerned about expense of the tests, and of course, don't want to waste their time either.

There are good reasons for this process, and in this page I attempt to explain the logic. In brief, the reasons are: 1). Confirm the diagnosis 2). Rule out common alternatives 3). Follow progress of the disorder. Here is the detail:

 

Goals of testing for Menieres's disease

Confirming the diagnosis:

The diagnosis of Meniere's is a serious one, which has long term implications for deterioration in hearing and balance. Why confirm it (or rule it out ?)

Differential diagnosis

The differential diagnosis of Menieres is broad and includes perilymph fistula, recurrent labyrinthitis, migraine, congenital ear malformations of many kinds, syphilis, Lyme disease, tumors such as acoustic neuroma, multiple sclerosis, posterior fossa arachnoid cysts, and other rare entities. Symptoms similar to Meniere's (fluctuating hearing, tinnitus, vertigo) can also be caused by impending strokes in the distribution of the anterior inferior cerebellar artery (Lee and Cho, 2003). Bilaterality of hearing fluctuation suggests a vascular cause such as migraine.

Measure functional status

In Meniere's disease, hearing and balance generally progressively worsen over decades. This may lead to disability from hearing loss or imbalance or both. Monitoring hearing loss guides the intensity of treatment. Monitoring balance is less helpful, but may also be useful in situations where persons are working in dangerous environments where good balance is required.
