简要总结
Aims: 1. To evaluate the effects of radiation therapy on the inner ear, among patients treated with radiation therapy for head and neck cancers using a wide battery of tests (Audiometry and tympanometry, vHIT, VEMP, ENG) ; 2. To correlate the mean total radiation dose to the cochlea with the effects on audiological and vestibular function
