title: Osteoradionecrosis of the temporal bone: a surgical technique of treatment.
abstract: Osteoradionecrosis of the temporal bone is a well-documented complication of radiotherapy to the ear, with potentially lethal complications. Three cases of advanced disease, treated surgically, are presented. In two of these, subtotal petrosectomy with blind-sac closure of the external auditory canal was carried out via an anterior approach. The enclosed space was obliterated with pedicled temporalis muscle. Primary healing took place. One case was similarly obliterated using a prolonged posterior incision. The wound broke down, requiring a microvascular free flap for closure. Radiotherapy jeopardizes the viability of skin flaps. An anterior incision bases the flap behind on the occipital and postauricular arteries. When radiotherapy has been used, this incision has theoretical and practical advantages over a standard posterior incision.
