Clinical trials of staged operation for a multichannel cochlear implant in two deaf patients are described. At the first stage, the tympanic cavity was opened under local anesthesia, and the conditions of the round window and cochlea were examined under an operation microscope. At this time, a round window stimulation was done to assess residual auditory nerve function. One month later the multichannel electrode was implanted.
