Maxillofacial surgery has proven to be an effective method for controlling OSA syndrome, and its results are as effective as those obtained with nasal CPAP. The presurgical evaluation, which includes polysomnography, physical examination, fiberoptic pharyngoscopy, and cephalometric analysis, is essential in directing surgical therapy. With phased reconstruction of the upper airway there is an excellent chance of correcting the obstructive process and eliminating the associated problems of OSA syndrome.
