Oral and maxillofacial surgery for the management of obstructive sleep apnea syndrome

The initial reports of treating obstructive sleep apnea using the uvulopalatopharyngoplasty were encouraging; however, as further trials of this procedure were reported, it began to show disappointing results. It was found that the retropalatal airway was not the only site of obstruction and procedures would need to be developed that would address obstruction in the other portions of the airway involved, notably in the retrolingual or hypopharyngeal portion of the ah-way. It was first reported by oral surgeons that mandibular surgery could also improve sleep apnea and through their work and the work of others, techniques have been developed using skeletal surgery to enhance the patency of the airway during sleep. This article describes some of these techniques and their indications, complications, and results.
