Abstract
In the past two years, the Hearing Rehabilitation Research Center (an affiliate of the Ear Research Institute, Los Angeles, California) cochlear implant program has grown tremendously. in August 1978 a total of 33 patients had been implanted with single-electrode cochlear implants (House et al., 1979). As of August 1980, 110 patients have been implanted; 66 by William F. House, M.D. and 44 by co-investigators. the prosthesis and the cochlear implant program have been described in the past (e.g., House et al., 1976; House etal., 1979; House, 1980).
