Abstract:
Objective To compare the characteristics of the SP-AP compound wave elicited by click and tone pip.Methods The electrocoehleogram was recorded with round window electrode,and waves were elicited by click and tone pips,respectively.Results The SP-AP compound waves were elicited 1,2,3,4 and 8 kHz tone pip and click.The amplitude of SP at each frequency was-13.56±8.7,-16.61±10.53,-10.13±14.75,-3.71±14.49,-2.99±5.4 and -4.44±10.81 μv,respectively.Conclusion Tone pip at 1,2,3,4,8 kHz can elicit SP,and produce frequency specific SP wave.This is helpful to identify the lesion site of auditory neuropathy.
