title: Cochlear implantation in a case of bilateral sensorineural hearing loss due to mumps.
abstract: It is well known that unilateral profound sensorineural hearing loss is caused by mumps; however, bilateral deafness is rare. Herein we report a case of bilateral profound hearing loss caused by mumps infection in a four-year-old boy. Labyrinthitis due to the mumps virus was suspected. His verbal understanding was poor, and he completely stopped talking. He was soon fitted with a hearing aid, but it proved insufficient. Thereupon, cochlear implantation was performed on his left ear. Six months after the operation, his speech perception and speech production were improved. In cases of bilateral profound hearing loss due to mumps infection conservative therapy is ineffective; therefore, cochlear implantation is recommended. Vaccine coverage for mumps virus is also strongly recommended in Japan.
