RESUMEN
Localized osteoradionecrosis of bony external auditory canal has been described as a late complication of external beam radiotherapy which is delivered to parotid bed after surgical resection of parotid malignancies. Diffuse osteoradionecrosis of temporal bone is rarely seen in such a setting and it is usually caused by resection of part of the bone for surgical clearance, followed by post-operative radiotherapy.This condition warrants aggressive treatment, in order to avoid potentially life threatening intracranial complications. In this report, we are presenting an uncommon case of extensive osteoradionecrosis which involved the entire temporal bone, in a patient who was treated for mucoepidermoid carcinoma of parotid twelve years ago, with total conservative parotidectomy and adjuvant radiotherapy.
