[Extratympanic electrocochleography in Ménière's disease].
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 ...
متن کاملThe Clinical Uses of Electrocochleography
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...
متن کاملNeurological applications of surface-recorded electrocochleography.
A new outpatient technique, involving the recording of auditory-evoked responses from scalp electrodes, is described. Responses are obtained from the cochlea, cochlear nerve, and auditory brain stem nuclei. The effects of various disorders on these responses are illustrated and the procedure is assessed as a diagnostic technique.
متن کاملIntrasubject Test-Retest Reliability in Tympanic Electrocochleography
To help establish the clinical reliability of electrocochleography (ECochG), we defined normal limits of variability for the summating potential (SP)/auditory nerve action potential (AP) amplitude ratio across multiple recording sessions from the same subjects . ECochG was recorded bilaterally from the tympanic membranes of 10 normal-hearing adults at six sessions separated by 2to 14-day interv...
متن کاملElectrocochleography for Ménière's disease: is it reliable?
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...
