The analysis aims at assessing the current trends in orthognathic surgery. The retrospective study covered a group of 124 patients with skeletal malocclusion treated by one team of maxillofacial surgeons at the University Hospital in Zielona Góra, Poland. Various variables were analysed, including demographic characteristics of the group, type of deformity, type of osteotomy used, order in which osteotomy was performed and duration of types of surgery. The mean age of the patients was 28 (ranging from 17 to 48, SD = 7). The group included a slightly bigger number of females (59.7%), with the dominant skeletal Class III (64.5%), and asymmetries were found in 21.8% of cases. Types of osteotomy performed during surgeries were divided as follows: LeFort I, segmental LeFort I, BSSO, BSSO with genioplasty, LeFort I with BSSO, LeFort I with BSSO and genioplasty, segmental LeFort I with BSSO, isolated genioplasty. Bimaxillary surgeries with and without genioplasty constituted the largest group of orthognathic surgeries (49.1%), and a slightly smaller percentage were one jaw surgeries (46.7%). A statistically significant correlation was found between the type of surgery and the skeletal class. In patients with skeletal Class III, bimaxillary surgeries were performed significantly more often than in patients with skeletal Class II (57.5% vs. 20.0%; p = 0.0002). The most common type of osteotomy in all surgeries was bilateral osteotomy of the mandible modo Obwegeser–Epker in combination with Le Fort I maxillary osteotomy (42.7%). The order of osteotomies in bimaxillary surgeries was mandible first in 61.3% of cases. The longest surgery was bimaxillary osteotomy with genioplasty (mean = 265 min), and the shortest surgery was isolated genioplasty (mean = 96 min). The results of the analysis show a significant differentiation between the needs of orthognathic surgery and the types of corrective osteotomy applied to the facial skeleton.

Study Design: Retrospective cohort study. Objective: The purpose of this study was to evaluate and share our experience with the surgery first approach (SFA) for correction of skeletal malocclusion. Methods: After consultation with the department of orthodontics, 45 patients with skeletal malocclusions suitable to undergo SFA were enrolled in this study (14 bimaxillary protrusion and 31 skeletal class III malocclusion). Le Fort I maxillary osteotomy, bilateral sagittal split ramus osteotomy, subapical osteotomy, and genioplasty were performed as required. After a healing period of 2 weeks, postoperative orthodontic treatment was started to achieve the final occlusion. Results: The mean duration of postoperative orthodontic treatment was 15.2 months, which is much shorter than the conventional orthodontic first approach (OFA) where presurgical orthodontic duration alone takes 12-24 months according to an individual. In the bimaxillary protrusion group, it was 18 months, which was significantly longer than for the other group ( P < .05). Conclusions: SFA offers an efficient alternative to conventional OFA with shorter total treatment duration, immediate marked improvement in facial profile, reduced biological costs, and similar operative stability. However, it comes at the cost of heightened challenges regarding case selection, accurate prediction, and surgical precision. With a joint venture between skilled and experienced surgeons and orthodontists, the outcome can be very promising.

Fibrous dysplasia (FD) is a disturbance of the mesenchymal tissue that accounts for 2.5% of all bone tumors and more than 7% of nonmalignant bone tumors. In the craniomaxillofacial region, FD affects the calvaria, skull base, zygoma, and jaws, the prevalent site being the maxilla (50% of cases). Therapy for craniomaxillofacial FD is surgical. The goals of surgery are to prevent functional disorders and restore facial symmetry, volume, and contour. In this article, we present a case of a young female patient affected by right orbital-zygomatic-maxillary FD. She had developed facial asymmetry and malocclusion that were corrected using the Schuchardt-Kufner osteotomy technique.
