Paper Abstract

Small electric signals appear on surface of a cochlea when the ear is stimulated by sound. A level of the signals can be measured of the electric activity of cochlea. The aim of the experiments was recording of changes of the cochlear potentials during argon laser stapedotomy. On the base of the recording the limits of the safe argon laser stapedotomy have been preliminary estimated. The series of argon laser pulses lasting 0.2-0.5 s and of 16 s interval between the pulses are preferable for safety of argon laser stapedotomy. The pulse peak power should be below 1 W.
