This paper reports a clinical evaluation on 30 deaf patients with cochlear implant (Cochlear Pty.), on whom the cochlear implantation has been performed at Tokyo Medical College, Kyoto University, Sapporo Medical College, University of the Ryukyu and Toranornon Hospital since 1985.

Average rates of speech sound perception for vowels and consonants were 100% and 81% res-pectively, in the condition of cochlear implant in addition to lipreading. The Speech Tracking Test score was 23 Bunsetsues per minute in an average. Speech sound perception tests were performed using video-taped materials for monosyllables, words and sentences. Correct responses were 43% on monosyllables, 40% on words and 48% on sentences for cochlear implant with lipreading condition. No adverse effects were observed, and it has been concluded that the cochlear implant is useful for the deaf patient.
