[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 کاملComparison of Transtympanic and Extratympanic Electrocochleography
Electrocochleography (ECoG) has been an important tool in the diagnosis of Meniere’s disease or endolymphatic hydrops. There are two methods employed, transtympanic and extratympanic. Many have regarded the results of these methods as being equally reliable. The purpose of this study is to determine any differences in sensitivity between the two methods. In this study patients with known endoly...
متن کاملExtratympanic electrocochleography in the diagnosis of auditory neuropathy/auditory dyssynchrony.
UNLABELLED The brainstem auditory evoked potential (BAEP) is being extensively used as a method for the evaluation of cochlear function in individuals with diagnosis of auditory neuropathy/auditory dyssynchrony (AN/AD). In the absence of otoacoustic emissions, many cases of AN/AD have been diagnosed by the presence of CM identified in the BAEP. AIM to demonstrate the clinical applicability of...
متن کاملSimultaneous Extratympanic Electrocochleography and Auditory Brainstem Responses Revisited
The purpose of this study was to revisit the two-channel, simultaneous click-evoked extratympanic electrocochleography and auditory brainstem response (ECoG/ABR) recording technique for clinical use in normal hearing participants. Recording the compound action potential (AP) of the ECoG simultaneously with ABR may be useful when Wave I of the ABR is small or diminished in patients with sensorin...
متن کاملComparison of the extratympanic electrocochleography in human and rabbit
Electrocochleography (ECoG) records the electrophysiologic activity of the most peripheral part of the auditory system, the inner ear cochlea and the 8th nerve. Auditory evoked potentials being recorded are Cochlear Microphonic (CM) and Summating Potential (AP). In order to provide the proper background for laboratory research and introducing an ECoG curve of a model animal, it was decided to...
