ABSTRACT Sound is transformed in to small electrical currents which stimulate the auditory nerves in the cochlea and generate the hearing sensation. Cochlear implantation (CI) has become an in creasing common procedure in the rehabilitation of selected cases of profound bilateral deafness. CI is a method which provides useful hearing and improves communication ability of adults and children with severe or profound bilateral sensor neural hearing loss. One hundred sixty patients (134 prelingual, 26 postlingual deaf) underwent cochlear implantation after full investigations in the Iranian Cochlear Implantation Center from 1993 to 1998. The majority of patients were 4 to 7 years old. The youngest patient was a 15-month-old child. Spontaneous reaction to environmental sound achieved in 87.3 percent. 71% of cochlear implanted deaf patients became able to use telephone and communicate with familiar speakers. Complication rate was as low as 3.75% and the most common complication was CSF gusher. |
