Abstract
During the radiotherapeutic treatment of pediatric oncology patients, they
would be at a latent risk of developing ionizing radiation-induced ototoxicity when the
cochlea or auditory nerve is located within the radiation field. Sensorineural hearing loss
(SNHL) is an irreversible late complication of radiotherapy, and its incidence depends on
various factors such as the patient’s hearing sensitivity, total radiation dose to the cochlea,
radiotherapy fractionation regimen, age and chemoradiation. Importantly, this complication
exhibits serious challenges to adult survivors of childhood cancer, as it has been
linked to impairments in academic achievement, psychosocial development, independent
living skills, and employment in the survivor population. Therefore, early detection and
proper management can alleviate academic, speech, language, social, and psychological
morbidity arising from hearing deficits. In the present review, we have addressed issues
such as underlying mechanisms of radiation-induced SNHL, audiometric findings of pediatric
cancer patients treated with radiotherapy, and management and protection measures
against radiation-induced ototoxicity.
