Orthognathic surgery and obstructive sleep apnea syndrome: a systematic review

In the scenario of Obstructive Sleep Apnea Syndrome (OSAS), Orthognathic Surgery (OS) corrected the deformities of the maxillary and mandibular bones OS has evolved a lot in the last two decades. OS treats patients with moderate and severe facial deformities, allowing the achievement of functional balance and harmony in facial aesthetics. Objective: To present the current findings of the importance of orthognathic surgery in the treatment of obstructive sleep apnea syndrome. Methods: A total of 78 articles were found involving mesh terms about Orthognathic Surgery and OSAS. Initially, was held the exclusion of existing title and duplications following the interest described in this work. After this process, the summaries were evaluated, and a new exclusion was held. Thus, 20 articles were included and discussed in this study. Major considerations and conclusion: In recent years, with the involvement and deepening of oral medicine in the diagnosis and treatment of OSAS, the role of OS in OSAS has become increasingly recognized. Early appropriate diagnosis and treatment can significantly improve patients' quality of life, reduce sudden death, and prevent various complications. OS corrects maxillofacial deformities through an incision of the upper and lower jaws, which has a significant relief effect on the symptoms of OSAS in patients with upper airway stenosis, especially in small mandibular patients.
