Inferior Sagittal Osteotomy of the Mandible with Hyoid Myotomy‐Suspension: A New Procedure for Obstructive Sleep Apnea

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.
