Resolution of pain and complete healing of mandibular osteoradionecrosis using pentoxifylline and tocopherol: a case report.

The radiation-induced fibroatrophic process (RIF) is a time-dependent adverse sequela to high-dose radiotherapy that can result in irreversible tissue death and bone exposure in the irradiated tissue. Osteoradionecrosis (ORN) is a late effect of RIF, described as bony exposure present for more than 3 months that can occur in 20% of patients irradiated for head and neck cancer. The intractable characteristics of ORN make both management and resolution of the disease process challenging, with 25% of cases recurring despite aggressive treatment with resection and reconstruction of the necrotic bone. In this article, we present a case of a 66-year-old man with unevoked ORN of the left posterior lingual mandibular cortex that was successfully treated and resolved with 6 months of pentoxifylline 400 mg twice a day and tocopherol 1000 IU every day.
