The efficacy of pentoxifylline/tocopherol combination in the treatment of osteoradionecrosis.

Background: Osteoradionecrosis (ORN) is an unfortunate complication of radiation therapy to the head and neck. Treatment has historically centered around hyperbaric oxygen therapy and surgical removal of necrotic bone. Recently, a new theory on the pathogenesis of ORN has proposed treatment with pentoxifylline (PTX) and tocopherol/vitamin E.
