Osteoradionecrosis (ORN) & Hyperbaric Oxygen Therapy
Osteoradionecrosis (ORN) is one of the most challenging late complications of radiation therapy to the head and neck. Radiation can damage blood vessels within the jawbone, reducing oxygen delivery and impairing the body's ability to heal. This can lead to exposed bone, chronic pain, infection, and significant impacts on quality of life.
Hyperbaric Oxygen Therapy (HBOT) plays an important role in the prevention and management of ORN. By delivering 100% oxygen under increased atmospheric pressure, HBOT helps:
✅ Increase oxygen delivery to damaged tissues
✅ Stimulate new blood vessel formation (angiogenesis)
✅ Enhance wound healing and tissue repair
✅ Reduce the risk of complications following dental extractions in previously irradiated patients
✅ Support recovery when used alongside surgical and dental interventions
Early identification of patients at risk for ORN and a multidisciplinary approach involving oncology, oral surgery, dentistry, and hyperbaric medicine can significantly improve outcomes.
As cancer survivorship continues to grow, awareness of ORN prevention and treatment options remains essential. Hyperbaric Oxygen Therapy continues to be a valuable tool in helping patients heal and maintain their quality of life after radiation treatment.
