What is soft tissue radionecrosis caused by?

Soft tissue radionecrosis is a condition that occurs when radiation exposure kills the soft tissues and isn’t able to regenerate normally. This most commonly occurs after radiation therapy for cancer and could occur in or around the region previously irradiated.

Is osteoradionecrosis an infection?

Jaw necrosis (osteoradionecrosis) It is not an infection in itself but because of the radiation treatment normal cells are destroyed leading to damaged arteries, reduced circulation and reduced healing ability of the bone.

How is soft tissue radionecrosis diagnosed?

Often the diagnosis can be confirmed by CT exam or MRI scanning. Demyelination of the spinal cord in the setting of delayed effects of radiation therapy and electrical pains into the lower extremity with the extension of the spine can be characteristic of soft tissue radionecrosis of the spine.

What happens to tissue after radiation?

Almost all chronic radiation complications result from scarring and narrowing of the blood vessels within the area which has received treatment. If this process progresses to the point that the normal tissues are no longer receiving an adequate blood supply, death or necrosis of these tissues can occur.

How do radiated tissues heal?

The use of Hyperbaric Oxygen Therapy to treat radiation tissue damage can heal the tissue by regenerating blood vessels, re-populating the damaged area with new stem cells, and accelerating all stages of wound healing.

Does radiation delayed tissue healing?

Radiation disrupts the normal process of wound healing at various stages. Pathologic changes include cellular depletion, extracellular matrix changes, and microvascular damage resulting in local tissue hypoxia.
