While most patients undergo orthognathic surgery for aesthetic purposes, aesthetic improvements are most often followed by postoperative functional complications. Therefore, patients must carefully decide whether their purpose of undergoing orthognathic surgery lies on the aesthetic side or the functional side. There is a wide variety of complications associated with orthognathic surgery. There should be a clear distinction between malpractice and complications. Complications can be resolved without any serious problems if the cause is detected early and adequate treatment provided. Oral and maxillofacial surgeons must have a full understanding of the types, causes, and treatment of complications, and should deliver this information to patients who develop these complications.

“…Due to differences in study methodologies, however, a wide range of values have been reported . Furthermore, torsion of the condyle‐ramus segment during fixation of proximal and distal bony segments in mandibular surgery may provoke post‐surgical condylar remodelling, resorption and potential long‐term instability of surgical correction …”

Structured Abstract Objectives To assess the effect of virtual surgical planning (VSP) on the accuracy of condylar seating in surgical cases involving Bilateral Sagittal Split Osteotomy (BSSO). An additional aim was to quantify differences between actual surgical outcome and planned virtual outcome. Setting and sample population A private practice in Charlotte North Carolina. Twenty‐five consecutively operated subjects prepared with VSP and twenty consecutively subjects operated with conventional surgery planning were enrolled. Material and Methods Cone beam computed tomography (CBCT) scans were obtained before surgery (T1) and post‐surgery after splint removal (T2). The T1 and T2 CBCTs were superimposed on the anterior cranial base using voxel‐based registration. Three dimensional (3D) models were built and oriented to a 3D Frankfurt horizontal. Displacement of corresponding condylar landmarks was measured. Results No significant difference was found between the VSP and conventional group in the magnitude of translation or rotation of the condyles following surgery. VSP surgical outcomes differed significantly from predicted positions at all landmarks. Virtual surgical planning does not prevent changes to condylar position as a result of surgery. Actual surgical results differed significantly from VSP‐predicted outcomes. Conclusions Virtual surgical planning did not reduce the changes to condylar position and angulation that resulted from conventionally planned orthognathic surgery.

The objective of this study was to evaluate the rates of relapse, temporomandibular joint (TMJ) changes or disease, and recurrence of idiopathic condylar resorption (ICR) and open bite following orthognathic surgery in patients with ICR. Six Class II patients (aged 19~51) who suffered from ICR and received orthognathic surgery on maxilla and mandible were evaluated. All 6 patients received Le Fort I osteotomy on maxilla. 5 patients received BSSRO with advanced genioplasty and fixation with Miniplate and 1 patient received Obwegeser-Dal Pont's method and fixation with APIS plate on mandible. Lateral cephalograms were taken at presurgical (T0), immediately post-surgical (T1) and 3 months post-surgical (T2), and 6 months post-surgical (T3) stages, and skeletal changes were analyzed with V-Ceph (CyberMed, Seoul, Korea) software. Age and sex, surgery method, fixation material, and post-operative complications of each patient were examined. Only one patient showed TMJ muscle-related disorder symptoms. Open bite recurrence was not observed in any of the 6 patients. Orthognathic surgery on maxilla and mandible shows no relationship with a recurrence of ICR or open bite.
