摘要: Purpose It has often been hypothesized that mandibular setback surgery causes narrowing of the pharyngeal airway. We examined whether airway narrowed after orthognathic in patients undergoing either or bimaxillary and amount was any different surgery. Materials Methods Cone-beam computed tomography scans were obtained for 21 who assigned to The anteroposterior dimension, lateral width, cross-sectional area, volume each subject's measured before Results showed significant both change dimension area on posterior nasal spine plane length differences between 2 groups. Conclusion smaller than
