Inferior sagittal osteotomy of the mandible with hyoid myotomy-suspension: a new procedure for obstructive sleep apnea

Abstract

Five patients were treated by inferior sagittal osteotomy and hyoid myotomy-suspension. In three of the patients, palatopharyngoplasty had previously failed. One of the patients was noted to have mandibular deficiency; the others had normal skeletal development. Nocturnal polysomnograms were performed preoperatively and postoperatively. All patients showed significant improvement.
