ECochG use in Meniere's Disease diagnosis

Question

In most clinical settings, it appears the diagnosis of Meniere's disease is based on the clinical judgment of the physician. In light of this, please address the clinical utility of ECochG.

Answer

ECochG offers "objective" data regarding the patient's condition. This data can be used to substantiate a diagnosis, justify a treatment regimen, and also monitor the effects of treatment. Among other benefits, the support of objective data regarding a particular diagnosis has important implications in the medico-legal arena.

The symptoms associated with Meniere's disease/endolymphatic hydrops can also be caused by other otologic/neurologic disorders. ECochG is helpful in this regard as well. That is, a positive electrocochleogram is very specific to endolymphatic hydrops. When combined with the ABR, this one-two punch provides important information about the status of the cochlea, auditory nerve, and brainstem.
