BACKGROUND:The aim of our study is to examine the possible complications, risk factors, and solutions encountered in orthognathic surgery in the light of the cases; we performed in our clinic. METHODS:This study includes a retrospective analysis of the records of 85 patients who underwent orthognathic surgery between 2015 and 2020 in Istanbul Pendik District Hospital Oral and Maxillofacial Surgery Service. The types of complications encountered during the operations were recorded in the study. Independent variables such as gender, age, number of operations, surgical site, and type of osteotomy were evaluated. Complications were evaluated according to the Clavien-Dindo classification. The data were presented for statistical analysis with a significance level of 0.05. RESULTS:Of the 85 patients included in the study, 40 were male and 45 were female. Of these patients, 65 had double chin operation and 20 had single chin operation. A total of 150 jaw osteotomies were performed, 78 of them in the maxilla and 72 in the mandible. While the maxilla was operated in 13 of the cases, in which single jaw operation was performed, only the mandible was treated in 7 of them. Complications were observed in 24 (10.57%) of a total of 227 osteotomies. Among the complications encountered, bleeding (8), nerve damage (7), malocclusion (3), infection (2), TMJ problems (2), bad split (1), and deviation at the tip of the nose (1) stand out, while complications were observed equally in men and women, complications were observed more frequently in cases with longer operative time (p<0.05). Complications were observed more frequently in bilateral sagittal split osteotomies (p<0.001) compared to Le Fort 1 osteotomies. Clavien-Dindo grade I complications were most common (72.04%) depending on the treatment. According to the Clavien-Dindo classification, there was no relationship between gender, age, duration of surgery, length of hospital stay, or surgical site, and the degree of complications (p≥0.05). CONCLUSION:Post-operative malocclusion, bleeding, inferior alveolar nerve injury, infection, poor division, and infection are the most common complications in orthognathic surgery. It can be associated with factors such as the duration of the operation, the number of operations, the site of the operation, and the type of osteotomy which performed. It is thought that positive contributions can be made to the success of the surgery by considering these factors in the treatment planning, during the operation and in the post-operative follow-up part.

“…Orthognathic surgery may be defined as repositioning the maxilla and/or mandible and/or their segments through a surgical approach to enhance the dentofacial function and appearance (in a stable manner) and health-related quality of life (24). The first mandibular osteotomy was performed by Hullihen in 1897 (24)(25)(26). After almost 50 years before, Blair (27) performed the first mandibular body osteotomy to correct of horizontal mandibular excess through an extraoral approach (17,24,26).…”

Objectives: This study compared the skeletal stability and pharyngeal airway changes after mandibular setback procedure using the titanium and resorbable plate and screws fixation. Materials and Methods: 28 patients with mandibular prognathism being treated with bilateral sagittal split ramus osteotomy (BSSRO) were randomly selected from titanium and resorbable fixations. Analyses of lateral cephalometric x-rays were performed according to preoperative (T0), 1st week post-surgery (T1), 3-6 months post-surgery (T2) and 1-year post-surgery (T3). The horizontal measurement (BX), vertical measurement (BY), and angle measurement (SNB and Mandibular Plane Angle; MPA) were studied for skeletal stability. The pharyngeal airway changes were observed by nasopharynx (NOP), uvula (UOP), tongue (TOP) and epiglottis (EOP). Results: There were no significant difference of mandibular setback in titanium (6.61?3.97 mm.) and resorbable groups (5.08?3.21 mm.). Significant MPA changes were found in both titanium and resorbable groups in 3-6 months post-surgery, but MPA still expressed significant changes in the resorbable group in 1-year post-surgery (2.29?0.59; p-value=0.006). The resorbable group was found significant EOP changes (-1.21?0.3 mm; p-value=0.02) in 3-6 months post-surgery, then gradually returned to no significant changes in 1-year post-surgery. Conclusion: This study could be demonstrated that osteofixation with resorbable plates and screws was comparable to titanium in long-term pharyngeal airway dimension, but a tendency to relapse, particularly mandibular plane angle.

“…Posteriormente, Wolford e colaboradores apresentaram uma modificação importante neste desenho (WOLFORD; BENNETT; RAFFERTY, 1987). A osteotomia moderna tipo Le Fort I foi desenvolvida por Obwegeser (OBWEGESER, 1965, 1969 onde a maxila foi totalmente mobilizada, com disjunção pterigomaxilar entre as tuberosidades maxilares e as placas pterigoides (NAINI, 2016). Este desenho foi modificado por Bennet e Wolford, que criaram a osteotomia Le Fort I com degrau, para evitar o fenômeno de "rampagem" da maxila (BENNETT; WOLFORD, 1985).…”
