INTRODUCTION Endolymphatic hydrops, the histopathological substrate of Ménière's disease, is an almost universal finding in postmortem studies of patients with this disease. The cause of hydrops is still unknown, as is the mechanism by which it causes progressive dysfunction of the sensory organs of inner ear. The fluctuating course of the disease complicates the interpretation of certain tests...

The clinical uses of electrocochleography are reviewed with some technical notes on the apparatus needed to get clear recordings under different conditions. Electrocochleography can be used to estimate auditory thresholds in difficult to test children and a golf club electrode is described. The same electrode can be used to obtain electrical auditory brainstem responses (EABR). Diagnostic testi...

INTRODUCTION Electrocochleography is the registration of an electrophysiological event which takes place in the cochlea after an acoustical stimulus. Most of the authors consider an increased summating potential (SP)/action potential (AP) ratio as characteristic of endolymphatic hydrops. METHODS A longitudinal, prospective study of a unilateral Ménière's population diagnosed according to the ...

The authors review some of the contrasts that Ménière's disease presents to the practicing otologist and describe recent findings in electrocochleography (ECochG) and vectornystagmorgraphy that have been of help in establishing the diagnosis in unusual cases. ECochG has also been useful in detecting the presence of the disease in the patient's better ear. The goals of medical and surgical treat...

Electrocochleography was performed on three patients to monitor the intravenous administration of tobramycin. When peak serum tobramycin levels exceeded 8-10 mug/ml an immediate dramatic reduction in cochlear output was observed, which recovered fully as serum levels fell. The patients had no auditory or vestibular symptoms either during or after treatment.

OBJECTIVE Evaluate the clinical use of electrocochleography (ECoG) for diagnosis/treatment of Ménière's disease among members of the American Otological Society (AOS) and American Neurotology Society (ANS). SUBJECTS Clinically active members of the AOS/ANS. MAIN OUTCOME MEASURE Survey responses. RESULTS A total of 143 responses were received from 344 possible respondents (41.6%). In suspe...
