Auditory achievements of cochlear implantation

: The cochlear implant, which stimulates the auditory nerve electrically, is a rehabilitative solution for the severely deaf who cannot benefit from a hearing aid. The implant enables them to rejoin the world of sound from which they were disconnected. We present the process of auditory diagnosis which determines the patient's suitability for cochlear implantation, the implant's tuning program and the rehabilitation process it entails. Each of the 22 implanted electrodes is checked through a computer program, and the specifications of the electrical stimulation are established to provide the most comfortable hearing level for the implanted device. These stimulation specifications determine the number of active electrodes and the ideal stimulation model. During the 8-week hearing-training program which follows implantation, the patients acquaint themselves with the new world of sound through which they will communicate with their environment. Of the 16 implanted patients 7 heard only via the implant, without the aid of lipreading, a result which is considered excellent. These patients are able to talk on the telephone with the aid of the implant. 1 patient refused to use the implant, while the others have had good to moderate results. Noteworthy is the fact that even those with only moderate results greatly benefit from the implant, and are not willing to function without it for even a single day.
