Abstract
Box surgery for obstructive sleep apnea (OSA) patients consists of mandibular surgery, including genioglossus advancement, hyoid suspension, and maxillomandibular advancement, as an airway reconstruction. This surgery was developed in the early 1980s. Thereafter, techniques were modified in each surgery for the enhancement of outcome and prevention of complications. However, the indication for surgery remains poorly defined due to the dynamicity of the upper airway, variability of the phenotype in OSA patients, and absence of a representative method for the obstruction site in the upper airway. As a result, box surgery is performed restrictively. On the development of an evaluation method including radiologic and endoscopic examination during sleep, the indications and surgical outcomes of each box surgery should be standardized and reevaluated. In this review, the development and limitations of box surgery will be discussed for the positive future of this surgery.
