[Hyperbaric oxygenation (HBO) in the treatment of radiogenic side effects]

Many reports show that late complications of radiotherapy can be successfully treated by hyperbaric oxygen (HBO). This synopsis attempts to review the literature to identify areas of clinical use and further research.

Clinical and experimental data about HBO treatment of radiation late effects are analysed. Mechanisms of hyperbaric oxygen in the treatment of late radiation side effects are discussed.

There is evidence in the literature that HBO is beneficial in the treatment of radiation cystitis, osteoradionecrosis of the mandible, hemorrhagic proctitis, soft tissue necrosis and neurologic deficits. The prophylactic use of HBO has shown to prevent the development of osteoradionecrosis after tooth removal and the loss of titanium implants in irradiated facial bones. The physiologic basis of HBO can be referred to induction of neoangiogenesis and revascularisation.

Clinicians can be encouraged to use hyperbaric oxygen for the treatment of radiation cystitis, osteonecrosis of the mandible, hemorrhagic proctitis, soft tissue necrosis and neurologic deficits following radiation therapy.
