Changes in the most constricted area were also noted. Associations between the directional movements of skeletal structures and the regional changes in airway volume were quantified. Presurgical and postsurgical measurements were collected for horizontal, vertical, and transverse movements of the maxilla and the mandible, along with changes in the nasopharynx, oropharynx, and total airways. 1 mm total, 35 subjects and Class III: ANB, \1 overjet, \1 mm total, 36 subjects). They were divided into 2 groups based on ANB angle, overjet, and occlusion (Class II: ANB.
Methods: Skeletal movements and airway volumes of 71 postpubertal patients (31 male, 40 female mean age, 18.8 years) were measured.
The aims of this study were to use cone-beam computed tomography to quantify the nasopharynx, oropharynx, and total airway volume changes associated with skeletal movements of the maxilla and mandible in a sample of patients undergoing 2-jaw orthognathic surgery for correction of skeletal malocclusion. Introduction: Findings from early cephalometric studies on airway changes after 2-jaw orthognathic surgery have been challenged because the previous anteroposterior interpretation of airway changes can now be evaluated in 3 dimensions.
