The awareness of the deleterious effects of obstructive sleep apnea (OSA) has increased over the past decade. Known symptoms of OSA include hypersomnolence, and cardiovascular and neurological diseases. Increased awareness of these conditions has led to an increase in the diagnosis and treatment options for patients with OSA. Conventional nonsurgical treatment options may be unacceptable or intolerable to some patients. In these situations, surgical management may be a viable option. Phase I surgery for OSA involves the surgical management of upper airway obstruction that does not involve maxillomandibular advancement surgery (phase II). A variety of solitary and combined surgical procedures have been developed to address upper airway obstruction. This lecture will review several commonly used techniques and emphasize, either alone or in combination, the latest advanced OSA surgery techniques, such as nasal reconstruction (internal and external nasal valve reconstruction, septoplasty, etc) hyoid advancement, elliptical genioglossus advancement, soft palate surgery (UPPP, LAUP, etc), and maxillomandibular advancements. Oral and maxillofacial surgeons managing the surgical obstructive sleep apnea patient will learn the latest advanced techniques in upper airway obstruction surgery. Emphasis will be on the correct diagnosis, treatment planning, indications, and latest research in these techniques for the surgical management of OSA.
