title: Assessment of permanent hearing impairment following radical megavoltage radiotherapy.
abstract: Twenty patients who had received unilateral radical megavoltage radiotherapy to the temporal bone had their hearing assessed by pure tone audiometry between 2 and 16 years after completion of treatment. Hearing loss was not detected in the irradiated ear when compared with the non-irradiated ear of each patient.
