摘要: ABSTRACT Objective: To evaluate longitudinal changes of the hyoid bone position and pharyngeal airway space after bimaxillary surgery in mandibular prognathism patients. Materials Methods: Cone-beam computed tomography scans were taken for 25 patients before (T0), 2 months (T1), 6 months (T2). The positional displacement was assessed using coordinates at T0, T1, T2. Additionally, volume each subject's measured.
