There is currently not sufficient evidence that hyperbaric oxygen (HBO) benefits the surgical removal of necrotic bone in osteoradionecrosis patients. This study aims at testing the hypothesis that HBO does improve healing after surgical removal of necrotic bone in irradiated previous head and neck cancer patients compared to not receiving HBO.
