Pharyngeal Airway Morphology in Skeletal Class III With Mandibular Asymmetry is Improved After Bimaxillary Orthognathic Surgery

PurposeThe relationship between pharyngeal airway morphology and jawbone movements in skeletal Class III patients with mandibular asymmetry after orthognathic surgery remains unclear. This study was to measure the changes bimaxillary evaluate associations movements.MethodsIn this retrospective cohort study, who underwent were enrolled. The predictor variable facial symmetry status divided into 2 groups, asymmetric (Group A) symmetric B). primary outcome variables parameters, including cross-sectional linear distances, area (CSA), minimum CSA (Min-CSA), volume; index preoperative 6-month postoperative imaging studies. Correlation analysis performed upper changes.ResultsTwenty-five included 15 Group A (mean age: 23.00 years; BMI: 22.83) 10 B 22.30 22.48). showed a higher than at T0; however, no significant differences compared T1. volume significantly decreased oropharynx T1, whereas it (P < .05). Lateral movement of point Menton positive correlations Min-CSA negative .05).ConclusionsPharyngeal exhibited an asymmetrical constricted before surgery. tendency adopt symmetrical less shape space reduced Surgical correction correlated improvement morphology. movements.
