| Abstract | ||||
| Aim: This retrospective study aims to estimate the oropharyngeal airway space changes following treatment with the Xbow appliance and compare it with Forsus appliance. Materials and Methods: This study involved pre- and post-treatment lateral cephalometrics of 63 adolescent patients with Class II mandibular retrognathism malocclusion, separated into three distinct groups; Group I: 21 patients (15 girls, 6 boys, mean age: 13±2.4) treated with Xbow, Group II: 21 patients (13 girls, 8 boys, mean age: 12±3.1) treated with Forsus, and Group III: 21 untreated class II patients (12 girls, 9 boys, mean age: 13±1.8) received no orthodontic treatment as control. Changes in lower and upper airway thickness, lower and upper adenoid thickness, lower and upper pharynx dimension were then analyzed. Results: The airway dimensions improved significantly with Xbow and Forsus compared to the control group. Xbow significantly improved all parameters except the lower pharynx dimension, which showed no significant changes across the groups (p = 0.357). Forsus showed significant alteration in all parameters except the lower airway thickness (p= 0.407). Xbow significantly increase the lower and upper airway thickness compared to Forsus and control groups (p < 0.001). Conclusion: Both Xbow and Forsus treatments yielded positive results in enhancing oropharyngeal airway dimensions in class II patients, with the Xbow treatment showing a more pronounced impact on both lower and upper airway thickness measurements. | ||||
