Trends in electrocochleography.
Currently there appears to be a resurgence of interest in the measurement of the peripheral-most electrical potentials of the auditory system. These measurements, known collectively as electrocochleography, may be used (1) to assess and monitor patients with Meniere's disease or endolymphatic hydrops, (2) to enhance wave I of the surface recorded ABR, and (3) as a means of monitoring the peripheral auditory structures during surgery. Various recording techniques and electrode types are reviewed and suggestions are provided for response interpretation in several patient populations.
