• | We assessed swelling after Le Fort I osteotomy and bilateral sagittal split osteotomy. |
• | Facial swelling at 1 week and 1 year after surgery was evaluated. |
• | Absence of facial bandages was a risk factor for swelling. |
• | Thin masseter muscle and large mandibular setback were also risk factors. |
• | Predicting the degree of facial swelling could help counsel patients. |
Abstract |
Objective |
To quantify facial swelling at 1 week after Le Fort I osteotomy and bilateral sagittal splitting ramus osteotomy in Class III patients and to identify factors contributing to the swelling based on clinical, morphologic, and surgical variables.
Study Design |
Data from 63 patients were examined in this single-center, retrospective study. Facial swelling was quantitatively measured by superimposing computed tomography data taken in the supine position at 1 week and 1 year postoperatively and extracting the area of maximum intersurface distance. Age, sex, body mass index, thickness of subcutaneous tissue, and of masseter muscle, maxillary length (A-VRP), mandibular length (B-VRP), and posterior maxillary height (U6-HRP), surgical movement (ΔA-VRP, ΔB-VRP, ΔU6-HRP), drainage method, and usage of facial bandages were examined. Multiple regression analysis was performed using the above factors.
Results |
The median swelling at 1 week postoperatively was 8.35 IQR (5.99–11.47) mm. Multiple regression analysis revealed three factors that were significantly associated with facial swelling: Use of postoperative facial bandages (P=0.03), masseter muscle thickness (P=0.03), and ΔB-VRP (P=0.04).
Conclusion |
Absence of a facial bandage, thin masseter muscle, and large horizontal mandibular movement are risk factors for facial swelling at 1 week postoperatively.
