[Cone-beam computed tomography evaluation of short- and long-term airway changes in patients with skeletal Class Ⅲ malocclusion treated by orthodontic therapy and bimaxillary surgery with or without mandibular setback surgery].

Purpose: To evaluate the short-term and long-term effects of pharyngeal airway in skeletal Class Ⅲ malocclusion patients who underwent bimaxillary surgery or isolated mandibular setback-orthodontic treatment.

Methods: The sample included 54 patients (28 males, 26 females) who were diagnosed with skeletal Class Ⅲ malocclusion. Patents in group A (n=28) underwent mandibular setback surgery and orthodontic treatment.

[Three-dimensional analysis of pharyngeal airway in skeletal Class III patients after sagittal split ramus osteotomy].

Objective: To analyze the three-dimensional changes of pharyngeal airway in patients with skeletal Class III malocclusion after the combined orthodontic and orthognathic treatment.

Methods: Twenty patients (9 males, 11 females) and 40 subjects with normal occlusion were involved in the study. Cone-beam computed tomography (CBCT) were performed on patients one week and six months after treatment.
