Complications of hyperbaric oxygen in the treatment of head and neck disease.

Hyperbaric oxygen has been advocated in the treatment of many head and neck diseases. Reports of such treatments have described eustachian tube dysfunction as the only complication. A review of patients receiving hyperbaric oxygen for head and neck diseases at The Mount Sinai Medical Center revealed serious complications, which included seizure, stroke, and myocardial infarction. In addition, follow-up study of these patients demonstrated that 11 patients treated for radiation-induced necrosis had an undiagnosed recurrence of cancer.
