Abstract
Radiotherapy has been widely used given its increase in the successful outcomes and cure of some cancers. AIM: To evaluate the functionality of the auditory system in patients who underwent radiotherapy treatment for head and neck tumors. MATERIALS AND METHODS: From May 2007 to May 2008, otorhinolaryngological and audiological evaluation (Pure Tone Audiometry (air and bone conduction), Speech Audiometry, Tympanometry, Acoustic Reflex testing and Distortion Product Otoacoustic Emissions) were performed in 19 patients diagnosed with head and neck neoplasia and treated with radiotherapy. Prospective case series study. RESULTS: 10.5% left ears and 26.3% right ears had bilateral hearing loss soon after radiotherapy according to ASHA criteria. CONCLUSIONS: Radiotherapy treatment for head and neck cancer has ototoxic effects. Early programs of auditory rehabilitation should be offered to these patients.
