Upper airways after mandibular advancement orthognathic surgery: A 4-year follow-up.

Introduction: The purpose of this study was to assess the stability of changes in the upper airways 4 years after orthognathic surgery in patients with skeletal Class II malocclusion.

Methods: A retrospective clinical study was conducted including 33 cone-beam computed tomography images from 11 patients (average age of 35.91 years) followed up longitudinally for 4 years.

Evaluation of the Post Orthognathic Surgery Satisfaction: a Comparative Cross-Sectional Study of Patients Class II and III.

The aim of this study was to analyze the degree of postoperative satisfaction regarding facial and dental esthetics, masticatory and respiratory function, and psychosocial factors in patients with dentofacial deformity Class II compared with Class III. The patients were divided into 2 groups with 50 patients in Group 1 (Class II) and 30 patients in Group 2 (Class III). Assessing the degree of postoperative satisfaction, the authors did not observe a significant difference between the groups in terms of improvements in the aesthetic and functional aspects and the psychological impact of the treatment.

Three-dimensional evaluation of superior airway space after orthognathic surgery with counterclockwise rotation and advancement of the maxillomandibular complex in Class II patients.

Objective: The aim of this study was to assess changes in the superior airway space (SAS) in Class II patients undergoing orthognathic surgery with counterclockwise rotation of the maxillomandibular complex (MMC).

Study Design: A total of 23 patients (15 females and 8 males; mean age, 33 years) with symptoms of respiratory disease (mouth breathing) were studied. The patients were subjected to computed tomography analyses at two time intervals: T1 (preoperatively) and T2 (postoperative minimum of 6 months).

Skeletal stability in orthognathic surgery: evaluation of methods of rigid internal fixation after counterclockwise rotation in patients with class II deformities.

Our aim was to assess the influence of internal fixation in skeletal stability on patients who had had counterclockwise rotation of the maxillomandibular complex and mandibular advancement procedures. We studied 60 records of 20 patients (14 female, 6 male), mean (range) age at operation 29 (16-50) years. The mean (range) postoperative follow-up was 15 (8-24) months.
