摘要：The aim of this study was to assess the airway volume of patients with Class III skeletal malocclusion undergoing bimaxillary orthognathic surgery. The sample consisted of 10 patients with Class III skeletal malocclusion undergoing bimaxillary orthognathic surgery. Through computed tomography, the three-dimensional volumetric measurements of the airways were determined using the Dolphin Imaging 11.7 program and were compared between the pre- and postoperative periods. Patients were divided into two groups, (1) airway narrowing and (2) airway enlargement. Group 1 showed a mean reduction of 66.16 ± 52.48 mm2 in the two-dimensional assessment of the airways and 2311.16 ± 1653.71 mm3 in the three-dimensional assessment (p≤ 0.05). On the other hand, group 2 increased 166.5 ± 73.13 mm2 and 4116 ± 1323.85 mm3. There was no correlation between the values obtained with bone movement, in mm (p≥0.05). Patients with class III deformities undergoing bimaxillary surgery, most with reduced airways, however, this decrease does not always occur to the same extent for all patients.
