This study aimed to evaluate the success of hyperbaric oxygen therapy (HBOT) and surgery in the treatment of mandibular osteoradionecrosis (ORN) in relation to the extent of the ORN. Twenty-seven patients with ORN were identified from a total of 509 patients with a history of primary oral or base of the tongue cancer; these patients had been treated with radiation therapy with curative intent between 1992 and 2006, with a radiation dose to the mandible of >/=50Gy. The ORN was staged according to the classification of Notani et al. The time from completion of radiation therapy to the development of ORN varied (median 3 years). Forty HBOT sessions were offered. After HBOT alone, 3 of 11 stage I lesions, 0 of 8 stage II lesions, and 0 of 8 stage III lesions had healed (P=0.0018). An absolute incidence of 5.3% ORN was found in this population. Of all sites irradiated in this study, the floor of the mouth was most associated with ORN (8.6%), whereas the cheek was least associated (0%). Based on the results of this study, HBOT can be recommended for stage I and II ORN and for selected cases of stage III ORN.
