osteoradionecrosis

Osteoradionecrosis is a condition that occurs when bone tissue becomes damaged and dies due to radiation therapy, often used to treat cancers in the head and neck. The radiation can reduce blood flow to the bone, leading to tissue breakdown and pain. Symptoms may include swelling, sores in the mouth, and difficulty with eating or speaking. Treatment typically involves managing symptoms and, in some cases, surgery to remove the affected bone. Prevention strategies focus on dental care before radiation therapy, as healthy oral hygiene can help reduce the risk of developing this complication.
