Abstract

Objective: This study aims to describe several clinical and paraclinical characteristics of patients undergoing orthognathic surgery at the National Hospital of Odonto-Stomatology in Hanoi, and to evaluate the change in their quality of life six months postoperatively. Subjects and Methods: A cross-sectional descriptive study was conducted on 48 patients (11 with class II dentofacial deformities and 37 with class III deformities) from July 2024 to July 2025. Clinical and paraclinical characteristics of both groups were analyzed based on preoperative assessments. Results: The mean age of patients was 21.6 ± 4.5 years. Patients with Class II deformities were older (mean 25.7 years) and predominantly female, whereas Class III patients were younger (mean 20.4 years) and predominantly male. Clinically, Class II patients exhibited convex facial profiles and positive overjet, while Class III patients presented concave profiles and negative overjet. Cephalometric analysis revealed significant skeletal discrepancies, with positive ANB values in Class II and markedly negative values in Class III. Dental parameters indicated preoperative incisor compensation in both groups. Conclusion: Class III deformities accounted for the majority of surgical cases. Clinical and paraclinical findings showed that Class III patients commonly had more severe skeletal discrepancies, with concave profiles, mandibular prognathism, and negative overjet, while Class II patients were characterized by convex profiles, maxillary protrusion, and mandibular retrusion.
