Orthognathic surgery in the treatment of obstructive sleep apnea syndrome

Abstract

Introduction: Obstructive sleep apnea syndrome (OSAS) is considered a public health problem associated with several comorbidities that affect quality and life expectancy. Currently, the use of devices that control air pressure during sleep is considered to be one of the best therapies to reduce apnea symptoms, however, it is difficult for patients to adhere. Thus, surgical treatment for this disorder, whose orthognathic surgery stands out, has high predictability and good results. Case report: The present study aims to report the clinical case of a 40-year-old female patient with severe OSAS and a high rate of apnea-hypopnea (AHI). On physical examination, mouth breathing, class II type dental-facial deformity, accentuated occlusal plane and bilateral temporomandibular joint dysfunction were observed. The treatment used was maxillomandibular advancement with counterclockwise rotation of the occlusal plane associated with chin repair. Follow-up was carried out for a period of two years, in which were observed a decrease in AHI eight months after surgery and a significant increase in the axial volume of the upper airways. Final considerations: The orthognathic surgery proposed for this case proved to be the appropriate treatment, presenting excellent results and long-term efficacy.
