[Simultaneous recording of electrocochleogram and auditory brainstem responses].
A method which can record and plot the electrocochleogram (ECochG) and auditory brainstem response (ABR) simultaneously with the same tracing was studied. The results demonstrated that the ECochG waves obtained by our method and that recorded alone were very similar. The -SP/AP values and the latencies of ABR obtained by those two methods had no statistically significant difference. It could help the recognition of ABR waves, particularly wave I. This technique was more beneficial in determination of wave I-V interpeak latencies and in differential diagnosis between cochlear and retro-cochlear lesions.
