抄録

Electrocochleography (ECochG) refers to examination of auditory evoked potentials, in which the electrical responses of the cochlea and the cochlear nerve evoked by sound stimuli are measured. Either a transtympanic or extratympanic electrode is used as the primary electrode for ECochG. The electrocochleogram consists of the cochlear microphonic (CM), summating potential (SP), and cochlear nerve compound action potential (AP). These responses are recorded within 3 msec of application of the acoustic stimuli. Although ECochG is technically and methodologically complex, it is very valuable for pathophysiological evaluation of cochlear function. In this report, the procedure and the clinical significance and application of ECochG are described in detail, with a review of the literature.
