Osteoradionecrosis (ORN) is a severe and debilitating condition that occurs when bone tissue becomes necrotic (dies) following radiation therapy, often used to treat cancers in the head and neck. The condition is primarily caused by radiation-induced damage to blood vessels, which impairs the bone's ability to heal and regenerate.Diagnosis typically involves clinical evaluation and imaging studies to assess the extent of bone damage. Management of ORN is challenging and often requires a multidisciplinary approach, including dental care, surgical intervention, and supportive therapies. Treatment options may include hyperbaric oxygen therapy, which helps promote healing by improving oxygen delivery to the affected tissues, and surgical debridement to remove necrotic bone. Preventive measures, such as meticulous oral hygiene and regular dental check-ups before and after radiation therapy, are crucial in minimizing the risk of developing ORN.
