Abstract
The first case of single channel Cochlear Implant in Japan was reported. This case was a 56 year—old male with bilateral profound hearing loss caused by labyrinthitis which was affected by meningitis 36 years ago A diagnosis of sensory deaf was carried out by electrical promontory testing (E.P.T.). An internal induction coil was fitted by surgical procedure on Dec. 3. 1980 and the first electrical stimulation was performed on Feb. 3, 1981. As a result of our first experience of single channel Cochlear Implant, Cochlear Implant is one of the useful approach to restore the deaf peoples.
