In maxillofacial surgery, hyperbaric oxygen treatment is almost exclusively used as an adjunctive therapy for osteoradionecrosis of the mandible in irradiated patients. It is also used to prevent the occurrence of osteoradionecrosis in the irradiated patient when dental surgery is indicated. Theoretically, hyperbaric oxygen therapy may also benefit the non-irradiated patient in maxillofacial surgery. For example, patients with persistent intraoral wound dehiscences after bone grafting.In this case series we present 6 non-irradiated, patients who underwent hyperbaric oxygen therapy because of compromised wound healing after intraoral bone grafting of the maxilla as a pre-implantological procedure. All patients were treated between 7 and 26 times with hyperbaric oxygen therapy at 2,5 ATA. All patients healed uneventful. In retrospect, almost all patients had a history of chronic maxillary sinusitis or trauma to the operated area. In conclusion, hyperbaric oxygen therapy seems to be an effective adjunctive therapy in the treatment of the non-irradiated patients with compromised intraoral maxillary bonegraft healing. Chronic maxillary sinus problems or a previous history of trauma may predispose to wound dehiscence after bone grafting.
