Cochlear implantation in the senior citizen age group using the Nucleus 22-channel device.

Cochlear implantation has become a recognized beneficial method of assisting in the rehabilitation of the profoundly deaf individual. The only device that is currently approved by the Food and Drug Administration for implantation in children and adults in the United States is the Nucleus 22-channel device. Since 1988, the Nucleus is the only device that has been implanted at the Mayo Clinic, Rochester, Minnesota. Fifty-six patients ranging in age from 3 to 85 have received implants. Twenty-five (45%) were over 55 and 14 (25%) were 65 or older. All of the patients over 55 are currently using their implants. Several of the patients over 65 are continuing to be gainfully employed. The benefits, complications, and results are addressed.
