Abstract

Irradiation to the head and neck area can lead to various possible otological complications. Nasopharyngeal carcinoma (NPC), being a prevalent disease in Hong Kong and Southern China, is the commonest indication for irradiation that we have encountered leading to such complications. Conventional radiotherapy for NPC, with one anterior facial field and two lateral opposing facial fields, subject both temporal bones to significant irradiation. Occasionally, a profound degree of sensorineural hearing loss necessitates the consideration of cochlear implantation for hearing rehabilitation. This paper summarizes our experience and results of cochlear implantation for a series of patients who had developed profound deafness subsequent to radiotherapy for treatment for NPC.
