Cases of obstructive sleep apnea are often submitted to mandibular advancement to improve the airway space and treat the pathology. Considering this procedure, this study analyzed and quantified the volumetric dimensional changes occurring in the airway space as a consequence of surgical mandibular advancement. This retrospective study was conducted on records from the Center for Treatment of Facial Deformities Hnary/Branemark PI Institute in the city of Bauru, state of São Paulo. The sample included 38 patients aged 18 to 45 years, of both genders, submitted to surgery for mandibular advancement or counterclockwise rotation, presenting preoperative and six-month postoperative tomographic records. After sample collection, the xstd images were analyzed on the software Xoran and the Go-Gn and Co-Me measurements were obtained. After this evaluation, the xstd images were imported to DICOM and analyzed on the software Dolphin Imaging 11.0, which allowed evaluation of the pre- and postoperative airway space volume. The results revealed that, in 100% of cases, there was statistically significant increase in the airway space, without significant differences in the gain of airway space volume between females and males. It was concludedthat both mandibular advancement surgery and counterclockwise mandibular rotation caused a significant increase in the airway space, and there was no difference between the gain in airway space between males and females.
