Benefit provided by a multi-electrode intracochlear implant to a prelinguistically deaf adult.

The authors describe the therapy and performance of a prelinguistically deaf adult using a multi-electrode, intracochlear implant. The post-operative test results show that this patient receives greater benefit with the cochlear implant than he received with a hearing aid.

Comparison of benefit from vibrotactile aid and cochlear implant for postlinguistically deaf adults.

Four postlinguistically deaf adults were evaluated presurgically with a one- or two-channel vibrotactile aid and postsurgically with a multichannel, multielectrode, intracochlear implant. Although the vibrotactile aid provided awareness of sound and enhanced flow of conversation, benefit to lipreading was small on videotaped tests and speech tracking. Scores on recorded, sound-only speech tests were not significantly above chance except in discrimination of noise from voice.
