[Hyperbaric oxygen therapy as a method of treatment of laryngeal and pharyngeal radionecrosis].
The authors described two cases of palatine tonsil carcinoma treated with surgery and subsequent radiation therapy after which occurred severe radionecrosis of the larynx, pharynx and oral cavity. These subjects were treated with hyperbaric oxygen therapy (HBO). Complete resolution of postradiation changes was observed. The authors described: 1) basic changes in the tissues caused by radiation therapy; 2) the mechanisms of healing activity of hyperbaric oxygen.
