|Hyperbaric oxygen therapy (HBOT) is a medical treatment defined as an intermittent inhalation of 100% oxygen in a hyperbaric chamber at a pressure higher than 1 absolute atmosphere. Physiological effect of HBOT is based on a dramatic increase in the amount of dissolved oxygen and leads to a net gain in oxygen concentration in tissues and subsequently induces growth of new vessels, restores tissue homeostasis, enhances white blood cells function and enhances effect of antibiotics. Health Canada has approved HBOT for several indications such as air or gas embolisms, carbon monoxide poisoning, decompression sickness, compromised grafts and flaps, nectoritizing infections, osteomyelitis and delayed radiation injury. HBOT is an established intervention in prevention and treatment of early osteoradionecrosis. Tooth extraction, dental implants and dental disease in irradiated areas can lead to the development of jaw and mandibular necrosis that could be prevented by the administration of a series of hyperbaric oxygen therapy before and after extraction or dental surgery. Besides its prophylactic role, HBOT has a remarkable therapeutic effect in established osteoradionecrosis. It promotes healing of the oral lesions, decreases pain, and improves truisms and muscle stiffness. HBOT should be considered in early infective processes that are resistant to initial treatment and must be considered as an adjuvant treatment in refractory mandibular/jaw osteomyelitis. It should be used in combination with antibiotics and debridement. HBOT is a safe and reliable treatment with very few contraindications and side effects. Clinical indications, common side effects and contraindications to therapy will be discussed.|
