Cochlear implants: update of the program at the University of British Columbia.

: Since 1982, we have performed 26 cochlear implants at the University of British Columbia. The first 14 patients were implanted with the House/3M single-channel unit and the last 12 have been implanted with the Nucleus 22-channel unit. This paper reviews the methods used in patient selection and rehabilitation and compares the results obtained in patients using a single-channel with those using a multi-channel unit.
