Abstract

We observed sensorineural hearing loss following X-ray irradiation to the malignant tumor of head and neck. There were 24 patients whose auditory organs lied within the irradiation field. Ten of these patients were affected by sensorineural hearing loss. Hearing loss occurred at a high frequency in elderly patients, epipharynx tumor and high dose of irradiation. Many cases revealed high tone hearing loss. Most cases showed about a 20∼30 dB hearing loss, so their impediment seemed not severe in daily life. In some of these cases, we could have temporal bone findings, but there were no particular findings relevant to sensorineural hearing loss.
