Radiation Necrosis

 

Radiation therapy is an accepted medical intervention for eliminating cancer cells and tumors from tissue. Long-term radiation damage, radionecrosis, may take years after radiation therapy to manifest itself. Radiation injury to bone (osteoradionecrosis) and to soft tissue and organs (e.g. radiation cystitis and radiation proctitis) can have life altering consequences.

 

Radiation used as treatment for head and neck cancer may damage the blood supply in the area of irradiated bone.  Osteoradionecrosis may develop; open wounds that do not heal properly may occur.

 

Hyperbaric oxygen therapy triggers the healing response to these areas, reducing or eliminating the necrotic consequences caused by the radiation:

 

  Especially beneficial for high-risk patients, such as irradiated patients requiring tooth extraction

 

  Allows more oxygen to reach the damaged areas; prevents tissues from dying from poor blood flow

 

  Boosts immune response to fight infections

 

  Promotes new bone growth

 

  Promotes new capillary growth

 

  Heals open wounds

 

  Stimulates angiogenesis in marginally viable tissue

 

In reconstructive surgery involving irradiated tissue, hyperbaric oxygen therapy prior to surgery promotes a well-vascularized wound, enhancing healing and the reconstructive process.

 

Suggested treatment schedule:

 

Marx Protocol:  for Osteoradionecrosis prior to dental extraction:

 

   One daily treatment, five days per week for a total of 20-30 treatments

 

   Post dental extraction: One daily treatment, five days per week for a total of 10 treatments

 

For Radiation soft-tissue necrosis:

 

One daily treatment, five days per week for a total of 20-60 treatments, as individual responses vary.
