Orthognathic Surgery for Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) involves obstruction or reduction of an individual's airway during sleep and is associated with several comorbidities. Patient evaluation includes detailed history, clinical and radiographic examination, endoscopy, and polysomnography. Management may be nonsurgical or surgical, and Phase II of the Stanford Protocol of surgical management involves maxillomandibular advancement (MMA). Surgical considerations (eg, degree of movement, timing of surgery) and potential complications specific to MMA are discussed in this review. With adequate planning and communication with the patient, MMA is effective in treating OSA, as measured with objective and subjective measures.
