Abstract
Obstructive sleep apnea is recognized as a major respiratory disorder in adults, characterized by a sharp decline or periodic interruption of airflow during sleep. The exact cause of this condition is uncertain and apparently multifactorial. Prognathic (Class III) cases are generally subject to the procedures of mandibular retrusion through sagittal ramus osteotomies that change the characteristics of the oropharynx, causing reduction of the airway space. The aim of this paper is to review the literature on the influence of orthognathic surgery for the correction of prognathism in the development of postoperative respiratory disorders such as obstructive sleep apnea.
