Delayed Radiation Injury (Soft Tissue and Bony Necrosis)
Radiation therapy saves lives but can cause delayed tissue damage years later. HBOT stimulates new blood vessel growth in radiation-damaged tissue.
What is Delayed Radiation Injury?
Delayed radiation injury (also called radiation necrosis or osteoradionecrosis) is damage to tissue that develops months to years after radiation therapy for cancer. It results from progressive blood vessel damage and tissue hypoxia.
Common manifestations include non-healing wounds in the head, neck, breast, and pelvis; osteoradionecrosis of the jaw (common after head and neck cancer treatment); radiation cystitis and proctitis; and soft tissue necrosis.
These complications can significantly impact quality of life and may require surgical intervention. HBOT is often the only effective treatment.
Raising Awareness & Providing Hope for Radiation Injuries
Complications may occur up to 20 years after radiation treatment
Cancer recovery rates are increasing, thanks to early detection and advancements in treatments. Yet after surviving cancer, many patients who received radiation therapy have underlying complications that may not cause symptoms for up to 20 years after their treatment.
Of the 1.6 million people diagnosed with cancer each year, about half will undergo radiation therapy. Radiation kills cancer cells but can also damage surrounding tissues. Visible symptoms of soft tissue injuries may not occur until years later. One study showed an average time of eight years and seven months post-treatment before radiation patients experienced these complications.
Key Facts About Radiation-Related Soft Tissue Injuries
Soft tissue radiation injuries most often arise after tooth extraction in patients with prior radiation therapy. The second most common group are those who have received radiation to treat gynecological, prostate, and colon cancer.
Areas especially prone to tissue injury are those covering bony prominences, surgical areas, and those on the face. Moist skin folds such as those under the breast, the armpit, and around the anus and genitals are also vulnerable.
Other signs of soft tissue injury can include blood in urine, rectal bleeding, vaginal discharge, and pain.
Radiation injuries may occur spontaneously or in response to a traumatic injury or infection. The wounds may appear superficial, and the pain associated with these injuries is often the reason a patient seeks treatment.
There Is Hope for Healing
Green Mountain Hyperbaric & Advanced Wound Care provides advanced wound care treatments and comprehensive care for soft tissue injuries that can include hyperbaric oxygen therapy (HBOT). HBOT speeds healing to wounds and soft tissue injuries by increasing the amount of oxygen carried in the blood. While receiving HBOT treatments, patients relax in a large, clear chamber surrounded by 100 percent oxygen at higher-than-normal atmospheric pressure.
Request a ConsultationCommon Manifestations
If you or someone you know is experiencing these symptoms, seek medical attention. Early intervention is critical for many of these conditions.
- Non-healing wounds in previously irradiated areas
- Jaw pain and exposed bone after dental work
- Bloody urine (radiation cystitis)
- Rectal bleeding (radiation proctitis)
- Chronic pain in radiated tissue
- Tissue breakdown and ulceration
- Difficulty swallowing (after head/neck radiation)
- Lymphedema
Multi-Specialty Radiation Injury Care
Treatment of radiation injury requires collaboration between oncology, surgery, wound care, and hyperbaric medicine specialists.
Wound Care
Specialized dressings and debridement techniques for radiation-damaged tissue.
Surgical Reconstruction
Flap coverage or tissue transfer for non-healing radiation wounds when needed.
Pain Management
Multimodal pain control for chronic radiation-related discomfort.
Pentoxifylline + Vitamin E
This combination therapy may help reduce radiation fibrosis in some patients.
How Hyperbaric Oxygen Therapy Helps
HBOT stimulates angiogenesis—the growth of new blood vessels in radiation-damaged tissue. This process, which develops over 20-40 treatments, gradually restores tissue oxygenation and healing capacity.
HBOT can be used to treat existing radiation injury or prophylactically before dental surgery or other procedures in previously irradiated tissue.
Key Benefits of HBOT for Radiation Injury
Treatment Protocol
For established radiation injury, treatment is typically 20-40 sessions at 2.0-2.4 ATA. For prophylaxis before dental surgery in irradiated tissue, 20 treatments before and 10 after surgery is standard.
The Marx protocol for osteoradionecrosis prevention has been used successfully for decades.

Diabetic Foot Ulcers
Diabetic foot ulcers are a leading cause of amputation. HBOT can reduce amputation rates by up to 75% when combined with comprehensive wound care.
Bone Infection
Chronic bone infections that fail to respond to surgery and antibiotics may respond to HBOT by enhancing oxygen delivery to infected bone.
