Osteoradionecrosis (ORN) is a serious complication of radiation therapy in cancer treatment where radiated bone becomes necrotic and exposed. ORN occurs most commonly in the mouth during the treatment of head and neck cancer, and can arise over 5 years after radiation. Common signs and symptoms include pain, difficulty chewing, trismus, mouth-to-skin fistulas and non-healing ulcers. The pathophysiology of ORN is fairly complex and involves drastic changes to bone tissue as a result of DNA damage and cell death caused by radiation treatment. Radiation therapy targeting tumor cells can affect normal cells as well, which can result in the death of bone tissue. Advances in radiation therapy have decreased the incidence of ORN, estimated at around 2%. Certain risk factors including the size and location of tumor, history of smoking or diabetes, and presence of dental disease can affect the chances of developing ORN. Osteoradionecrosis is difficult to prevent and treat. Current prevention strategies are aimed at avoiding excess doses of radiation as well as maintaining excellent dental hygiene. Treatments are variable depending on the provider and disease severity, and can range from medical treatment with antibiotics to hyperbaric oxygen therapy (HBO) to surgical debridement or reconstruction.
