Management of obstructive sleep apnea by maxillomandibular advancement surgery in an edentulous patient.

BACKGROUND Maxillomandibular advancement (MMA) surgery is a surgical treatment option for treating the patients with obstructive sleep apnea (OSA). Surgical treatment of OSA by MMA surgery is a problem when it is encountered with an edentulous patient because of the intermaxillary fixation problem of the jaws. A paucity of information is available concerning MMA surgery for edentulous patients. MATERIALS AND METHODS In this case report, we present the preoperative planning, orthognathic surgery, and postoperative phases of a 49-year-old edentulous severe OSA (apnea hypopnea index, 81.9 event/hr) patient who underwent MMA surgery. RESULTS Polysomnographic examination 9 months after surgery revealed normalization of the somnographic evaluations (apnea hypopnea index, 1.3). CONCLUSIONS The results reported in the present case showed that the surgical treatment of OSA by MMA surgery in edentulous patients could be successfully done. Further critical evaluations of this approach for the surgical treatment of edentulous OSA patients are needed.
