Abstract
PURPOSE The primary purpose of this study was to develop a new machine learning model for the surgery/non-surgery decision in class III patients and evaluate the validity and reliability of this model. METHODS The sample consisted of 196 skeletal class III patients. All the cases were allocated randomly, 136 to the training set and the remaining 60 to the test set. Using the test set, the success rate of the artificial neural network model was estimated, along with a 95% confidence interval. To predict surgical cases, we trained a binary classifier using two different methods: random forest (RF) and logistic regression (LR). RESULTS Both the RF and the LR model showed high separability when classifying each patient for surgical or non-surgical treatment. RF achieved an area under the curve (AUC) of 0.9395 on the test set. 95% confidence intervals were computed by bootstrap sampling as lower bound = 0.7908 and higher bound = 0.9799. On the other hand, LR achieved an AUC of 0.937 on the test set. 95% confidence intervals were computed by bootstrap sampling as lower bound = 0.8467 and higher bound = 0.9812. CONCLUSIONS RF and LR machine learning models can be used to generate accurate and reliable algorithms to successfully classify patients up to 90%. The features selected by the algorithms coincide with the clinical features that we as clinicians weigh heavily when determining a treatment plan. This study further supports that overjet, Wits appraisal, lower incisor angulation, and Holdaway H angle can be used as strong predictors in assessing a patient's surgical needs.

Complications of Surgically Assisted Rapid Maxillary/Palatal Expansion (SARME/SARPE)-A Retrospective Analysis of 185 Cases Treated at a Single Center. J Clin Med 2024; 13:2053. [PMID: 38610817 PMCID: PMC11012378 DOI: 10.3390/jcm13072053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 03/19/2024] [Accepted: 03/30/2024] [Indexed: 04/14/2024] Open
Abstract
Objectives: The study aims to assess and classify complications in patients treated for maxillary transverse deficiency using surgically assisted rapid maxillary/palatal expansion (SARME/SARPE) under general anesthesia. The classification of the complications aimed to assess the difficulty of their treatment as well as estimate its real cost. Methods: The retrospective study covered 185 patients who underwent surgery for a skeletal deformity in the form of maxillary constriction or in which maxillary constriction was one of its components treated by a team of maxillofacial surgeons at one center (97 females and 88 males, aged 15 to 47 years, mean age 26.1 years). Complications were divided into two groups: early complications (up to 3 weeks after surgery) and late complications (>3 weeks after surgery). In relation to the occurrence of complications, we analyzed the demographic characteristics of the group, type of skeletal deformity (class I, II, III), presence of open bite and asymmetry, surgical technique, type and size of appliance used for maxillary expansion, as well as the duration of surgery. Results: In the study group, complications were found in 18 patients (9.73%). Early complications were found in nine patients, while late complications were also found in nine patients. Early complications include no possibility of distraction, palatal mucosa necrosis, perforation of the maxillary alveolar process caused by the distractor and asymmetric distraction. Late complications include maxillary incisor root resorption, no bone formation in the distraction gap, and maxillary incisor necrosis. None of the patients required prolonged hospitalization and only one required reoperation. Conclusions: Complications were found in 18 patients (9.73%). All challenges were classified as minor difficulties since they did not suppress the final outcome of the treatment of skeletal malocclusion. However, the complications that did occur required additional corrective measures. Surgically assisted rapid maxillary expansion, when performed properly and in correlation with the correct orthodontic treatment protocol, is an effective and predictable technique for treating maxillary constriction.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2024; 125:101795. [PMID: 38340958 DOI: 10.1016/j.jormas.2024.101795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 02/05/2024] [Accepted: 02/06/2024] [Indexed: 02/12/2024]
Abstract
OBJECTIVE Determine the main complications of orthognathic surgery in patients with cleft lip and palate. METHODS PubMed, LILACS, Cochrane, Embase, Scopus, and Google Scholar were systematically reviewed. Studies addressing the complications of orthognathic surgery in patients with cleft lip and palate were included. For the search, the strategy was used with the descriptors extracted from MeSH "Cleft Palate", "Orthognathic Surgery" and "Complications". The Newcastle-Ottawa Scale (NOS) was used to assess the risk of bias in the included studies. Patients of any sex, age, and ethnicity with cleft lip and palate submitted to orthognathic surgery were included in this systematic review. The study followed the PRISMA 2020 standards and was registered in PROSPERO with protocol CRD42020195927. RESULTS In the initial search, 1090 articles were found and after applying the inclusion and exclusion criteria, eleven studies were selected. The sample consisted of 629 patients who underwent Orthognathic Surgery, with an average age of 21.52 years. The majority of patients (390) presented unilateral transforamen proposals. In total, 150 complications were identified in the included studies, the most frequent being relapse of movement with 77 cases (51.3 %). Other reported, but less frequent, complications were gingival recession with root exposure, premaxillary mobility, intraoperative hemorrhage, fistulas and infection and velopharyngeal impairment. Most included studies did not have a control group, making meta-analysis unfeasible. Seven of the included studies presented a low risk of bias according to the NOS. CONCLUSIONS Orthognathic surgery in cleft patients is a safe procedure, however it presents particularities and more complications when compared to a non-cleft patient. In this study, the most common complication found was the relapse, and the surgeon must be aware of this complication and others, and try to minimize its negative effects on the patient. We strongly recommend further investigations with detailed methodologies, control groups, well-described criteria for reported complications, and comprehensive sample characteristics to provide higher-quality evidence.

Abstract
Increased facial profile convexity has a common occurrence in the population and is a primary reason for seeking orthodontic treatment. The present study aimed to compare the perceived changes in facial profile appearance between patients treated with combined orthognathic/orthodontic treatment versus only orthodontic camouflage treatment. For this reason, 18 pairs of before- and after-treatment facial profile photos per treatment group (n = 36 patients) were presented to four types of assessors (surgeons, orthodontists, patients, laypeople). Ratings were recorded on 100 mm visual analogue scales depicted in previously validated questionnaires. All rater groups identified minor positive changes in the facial profile appearance after exclusively orthodontic treatment, in contrast to substantial positive changes (14% to 18%) following combined orthodontic and orthognathic surgery. The differences between the two treatment approaches were slightly larger in the lower face and the chin than in the lips. The combined orthodontic and orthognathic surgery interventions were efficient in improving the facial appearance of patients with convex profile, whereas orthodontic treatment alone was not. Given the significant influence of facial aesthetics on various life aspects and its pivotal role in treatment demand and patient satisfaction, healthcare providers should take these findings into account when consulting adult patients with a convex facial profile.

Abstract
OBJECTIVES The aim of this study was to evaluate the sensory function of the infraorbital nerve after orthognathic surgery (OS). MATERIALS AND METHODS Patients who underwent Le Fort I osteotomy with or without BSSO for dentofacial deformity treatment were studied. Two groups were created according to whether BSSO was performed. Class A tests were performed to determine the degree of peripheral nerve damage. The Class B test was performed if decreased sensation was detected in at least one of these tests. A Class C test was performed if abnormal sensation was detected. RESULTS Twenty-eight patients (n=56) who underwent OS were included in this prospective study. Of the patients, 57.1% were female, 42.9% were male, and the mean age was 24.6 (±3.8). Seven patients were in group 1 (n=14), and 21 patients were in group 2 (n=42). In both groups, there were statistically significant differences between T1 and T2 (p<0.001), and the mean NSD score at T2 was higher than that at T1. The mean NSD score in the single jaw group was higher than that in the double jaw group at all time points. CONCLUSIONS Bimaxillary surgeries had a negative effect on the somatosensory changes that developed in the early period. The upper lip's somatosensorial recovery was faster than IOR and single jaw recovery was faster than double jaw. CLINICAL RELEVANCE Maxillofacial surgeons performing orthognathic surgery should be aware that in double jaw operations, changes in the somatosensory function of the ION are more severe.

Abstract
PURPOSE The purpose of this study was to analyze the patients clinically who underwent reoperation after certain Orthognathic procedures, and to assess the reoperation rate. Furthermore, the authors also evaluated the incidence of intraoperative and postoperative complications that led to the need for reoperation. METHODS Total 526 patients were selected who underwent Orthognathic surgery between July 2008 and February 2022 at the Department of Oral and Maxillofacial Surgery in Pusan National University Dental Hospital by single surgeon. All the patients information were extracted from electronic database of our university. Demographic, radiologic, intraoperative, and postoperative data were recorded and compiled. RESULTS Out of 526 patients, 265 (50.3%) were males and 261 (49.6%) were females. The total number of patients who showed complication is 89 (16.9%) and the patients who underwent reoperation are 17 (3.2%). The common complications that occurred were postoperative sensory disturbance (31; 5.8%), unwanted fractures (17; 3.2%), intraoperative nerve injury (11; 2%), wound dehiscence (11; 2%), infection (10; 1.9%), tooth injury (2; 0.3%), and others (18; 3.4%). The serious complications that led to reoperation include severe bleeding (6; 1.1%), unesthetic results (5; 0.9%), non-union of maxilla (4; 0.7%), and failed osteosynthesis (2; 0.3%). After 2018, all the orthognathic surgeries were performed with the help of virtual surgical planning. After application of virtual surgical planning, the number of patients with complications statistically decreased. CONCLUSION The present study showed that the reoperation rate after orthognathic surgery was low, this rate was more decreased after applying 3-dimensional virtual surgery and 3-dimensional printed plate, especially in unesthetic cases.

Abstract
AIM The aim of this study was to retrospectively investigate the risk factors and their association on bimaxillary osteotomies to be able to improve patient selection and bimaxillary osteotomy planning. MATERIAL AND METHODS Patients treated with a bimaxillary osteotomy were included in the study. The complications were collected retrospectively from the patient data records. The effects of certain predictor variables on complication rates were also studied. RESULTS Sixty-one patients (48.0%) suffered from peri- or postoperative complications, or both. Twenty-five various perioperative complications were reported on 25 patients (19.6%) and 63 postoperative complications on 46 patients (36.2%). Ten patients (7.8%) suffered from both perioperative and postoperative complications. The effect of various predictor variables (sex, age, general health, type of malocclusion, surgery planning, use of bone grafts, and type of maxillary or mandibular movement) on complications was investigated, but we could not find any single factor to affect significantly on complication rate. CONCLUSION Both perioperative and postoperative complications are common in bimaxillary surgery, which must be noted in patient preoperative information. However, life-threatening complications are rare. Patient profile, bone grafting, type of osteosynthesis, or segmentation of the maxilla do not seem to affect the complication risk.

Abstract
INTRODUCTION The expansion effects of several new microimplant-assisted rapid palatal expanders (MARPEs) manufactured by 3-dimensional printing technology were evaluated by finite element analysis (FEA). The aim was to identify a novel MARPE suitable for treating maxillary transverse deficiency. METHODS The finite element model was established using MIMICS software (version 19.0; Materialise, Leuven, Belgium). First, the appropriate microimplant insertion characteristics were identified via FEA, and several MARPEs with the above insertion patterns were manufactured by 3-dimensional printing technology. Then, the stress distribution and displacement prediction of the 4 MARPEs and hyrax expander (model E) were evaluated via FEA: bone-borne (model A), bone-tooth-borne (model B), bone-mucous-borne (model C), bone-tooth-mucous-borne (model D). RESULTS Monocortical microimplants perpendicular to the cortical bone on the coronal plane resulted in better expansion effects. Compared with a conventional hyrax expander, the orthopedic expansion of each of the 4 MARPEs was far larger, the parallelism was greater, and the posterior teeth tipping rate was lower. Among them, the expansion effects of models C and D were the best; the von Mises peak values on the surfaces of the microimplants were smaller than those of models A and B. CONCLUSIONS This study may demonstrate that the 4 MARPEs obtained more advantageous orthopedic expansion effects than a hyrax expander. Models C and D obtained better biomechanical effects and had better primary stability. Overall, model D is the recommended expander for treating maxillary transverse deficiency because its structure acts like an implant guide and is beneficial for the accurate insertion of the microimplant.

Prevalence of Temporomandibular Disorders in Orthognathic Surgery patients: A systematic review conducted according to PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. J Oral Rehabil 2023; 50:1093-1100. [PMID: 37309105 DOI: 10.1111/joor.13534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 05/23/2023] [Accepted: 05/29/2023] [Indexed: 06/14/2023]
Abstract
BACKGROUND Orthognathic surgery is done to treat a variety of dentofacial abnormalities, but a wide gap still remains on how it can result in temporomandibular joint dysfunction (TMD). The primary goal of this review was to assess the effects of various orthognathic surgical techniques on the emergence or exacerbation of TMJ dysfunction. METHODS A comprehensive search was conducted across several databases using Boolean operators and MeSH keywords related to temporomandibular joint disorders (TMDs) and orthognathic surgical interventions, with no limitation on the year of publication. Two independent reviewers screened the identified studies based on predetermined inclusion and exclusion criteria, followed by a risk of bias assessment using a standardised tool. RESULTS Five articles were considered for inclusion in this review. A greater number of females opted for surgical options than their male cohorts. Three studies were of prospective design, 1 of retrospective and 1 of observational type. Mobility on lateral excursion, tenderness on palpation, arthralgia and popping sounds were the TMD characteristics that showed significant differences. Overall, orthognathic surgical intervention did not show an increase in TMD signs and symptoms as compared to nonsurgical counterparts. CONCLUSION Though orthognathic surgery reported greater cases of some TMD symptoms and signs as compared to the nonsurgical cohorts in four studies, the conclusive evidence is debatable. Further studies are recommended with a longer follow-up period and greater sample size to determine the impact of orthognathic surgery on TMJ.

Abstract
In individuals who have sustained maxillofacial trauma, inadequate nutrition is often a sequela and may lead to complications. The purpose of this study was to investigate the association between preoperative laboratory values and postoperative complications in patients with maxillofacial trauma requiring surgical intervention. A retrospective cohort study of patients with maxillofacial trauma requiring surgical repair from 2014 to 2020 was performed at a single academic Level I Trauma Center. The primary predictor variables were preoperative laboratory values including serum albumin, white blood cell count, absolute neutrophil count, and lymphocyte count. Complications related to surgical reconstruction of facial injuries represented the primary outcome variable. The patient cohort included 152 patients, of whom 50 (32.9%) were female. When controlling for all other variables, female gender (odds ratio=2.08, 95% confidence interval, 1.02-4.21; P =0.04) and number of procedures performed ( P =0.02) were the only statistically significant predictors of postoperative complications. There were no significant differences between the complication groups for age ( P =0.89), injury severity score ( P =0.59), hospital length of stay ( P =0.30), serum albumin ( P =0.86), hemoglobin ( P =0.06), white blood cell count ( P =0.20), absolute neutrophil count ( P =0.95), lymphocyte count ( P =0.23), or absolute neutrophil/lymphocyte count ratio ( P =0.09). In this study, it was found that only gender and the number of procedures performed significantly predicted postoperative complications, while preoperative nutritional laboratory values did not. Further study with a larger cohort of patients is likely required.

Ebker M, Goedecke M, Wollersheim T, Heiland M, Ebker T. Maxillomandibular advancement is a safe procedure in patients with obstructive sleep apnoea. Results of a retrospective study. Br J Oral Maxillofac Surg 2023; 61:491-496. [PMID: 37517940 DOI: 10.1016/j.bjoms.2023.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 06/18/2023] [Accepted: 07/06/2023] [Indexed: 08/01/2023]
Abstract
Obstructive sleep apnoea (OSA) is a syndrome with a high burden on public health. Maxillomandibular advancement (MMA) has proven to be a highly effective treatment option. This retrospective analysis evaluated the safety of maxillomandibular advancement with rotation in patients with OSA. A total of 63 patients with OSA were included in this study. Surgical treatment by maxillomandibular advancement was virtually planned based on preoperative cone beam computed tomography (CBCT). A 3D printed guide and a customised implant were used for surgical transfer. The safety of MMA was evaluated based on the necessity of postoperative intermediate care unit (IMCU) stay, duration of stay in hospital, and recording of medical complications. A total of 63.5% of the OSA patients treated by MMA (n = 40/63) were postoperatively transferred from the recovery room directly to the regular ward, while 36.5% of the patients (n = 23/63) stayed on IMCU for at least one night. On average, the length of hospitalisation was four days after surgery. One patient from the ward group and one patient from the IMCU group developed a major complication according to Clavian-Dindo classification grade IV. MMA is a safe surgical procedure. The necessity for postoperative monitoring in an IMCU setting should be based on an individual risk evaluation. However, since major complications can occur, MMA should be performed as an inpatient procedure in a hospital with available intensive medicine care. This study underlines the safety of MMA in OSA patients.

Bouchard C, Sanscartier PK. Nonunion in Orthognathic Surgery: A Case-Series of 15 Patients. J Oral Maxillofac Surg 2023:S0278-2391(23)00396-8. [PMID: 37220869 DOI: 10.1016/j.joms.2023.04.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 04/22/2023] [Accepted: 04/27/2023] [Indexed: 05/25/2023]
Abstract
BACKGROUND Bone nonunion is extensively studied in the orthopedic literature, but the knowledge in oral and maxillofacial surgery, specifically orthognathic surgery, is scarce. Since this complication has a significant negative impact on postoperative management of patients, more studies are needed. PURPOSE To report the characteristics of patients presenting with bone nonunion after orthognathic surgery. STUDY DESIGN, SETTING, SAMPLE This is a retrospective case-series study on subjects who underwent orthognathic surgery between 2011 and 2021 and developed nonunion. Inclusion criteria were mobility at the site of the osteotomy and the need for a second surgical intervention. Exclusion criteria were an incomplete medical chart; the absence of nonunion upon surgical exploration, or radiological evidence of nonunion; cleft lip/palate; or syndromic patients. MAIN OUTCOME VARIABLE The outcome variable was bone healing after nonunion care. COVARIATES Demographics (age, sex), medical/dental comorbidities, type of surgery (type of fixation, bone grafts, Botox injection), amplitude of movements, nonunion treatment. ANALYSES Descriptive statistics were computed for each study variable. RESULTS The sample was composed of 15 patients (11 females, mean age 40.4 years old) with nonunion (maxilla: 8 cases, mandible: 7 cases) out of 2036 patients who underwent orthognathic surgery during the period studied (incidence 0.74%). Nine (60%) were bruxers, three were smokers (20%) and one had diabetes. Mean forward movement of the maxilla was 6.55 mm (4-9 mm) and 7.71 mm (4.8-12 mm) for the mandible. All patients but one (who refused surgery) were treated by curettage of fibrous tissue and new hardware placement. In addition, 11 received a bone graft, and 4 had Botox injections. All osteotomies healed after the second surgical intervention. CONCLUSION Curettage with or without grafting appears to be a good strategy for the cure of nonunion. Bruxism may be a risk factor (60% of patients were bruxers in this study).

Causes of Reoperation Consultation and Clinical Review of Actual Reoperation After Previous Orthognathic Surgery. J Craniofac Surg 2023:00001665-990000000-00627. [PMID: 36922388 DOI: 10.1097/scs.0000000000009271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 12/11/2022] [Indexed: 03/18/2023] Open
Abstract
OBJECTIVE To investigate the causes of reoperation consultation, and the actual percentage and procedures of reoperation after previous orthognathic surgery. METHODS The samples consisted of 30 patients who visited our clinic for reoperation consultation from October 2015 to September 2021 (6 males and 24 females; mean age at reoperation consultation, 28.4 y). Patient's causes of reoperation consultation were divided into "esthetic dissatisfaction," "airway changes," "temporomandibular disorders," "uncomfortable occlusion," and "other complications". In terms of esthetic dissatisfaction, the more detailed esthetic problem was evaluated by the clinical chart, facial photographs, and radiographs. In patients who actually underwent reoperation, the actual percentage and procedures of reoperation were investigated. RESULTS The most prevalent causes for reoperation consultation were "esthetic dissatisfaction" (n = 21, 70.0%), followed by "airway changes" (n = 11, 36.7%), "uncomfortable occlusion" (n = 8, 26.7%), "other complications" (n = 5, 16.7%), and "temporomandibular disorder" (n = 4, 13.3%). Less than half of patients actually underwent reoperation (n = 13, 43.3%). Actual reoperation procedures included minor revision surgery, reconstruction surgery, or complete reoperation according to the patient's need. In case of complete reoperation, more accurate and predictable results were obtained by using virtual surgical planning, customized surgical guides, titanium surgical plates made with computer-aided design and computer-aided manufacturing technique, and a 3-dimensional printing method. CONCLUSION It is important to communicate with patients about expectations for facial esthetic improvement by orthognathic surgery for obtaining the patient's postoperative satisfaction.

Early Outcomes and Risk Factors in Orthognathic Surgery for Mandibular and Maxillary Hypo- and Hyperplasia: A 13-Year Analysis of a Multi-Institutional Database. J Clin Med 2023; 12:jcm12041444. [PMID: 36835979 PMCID: PMC9965345 DOI: 10.3390/jcm12041444] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 01/29/2023] [Accepted: 02/09/2023] [Indexed: 02/16/2023] Open
Abstract
BACKGROUND Orthognathic surgery (OS) is a frequently performed procedure for the correction of dentofacial deformities and malocclusion. Research on OS is mostly limited to single-surgeon experience or single-institutional reports. We, therefore, retrospectively analyzed a multi-institutional database to investigate outcomes of OS and identify risk factors for peri- and postoperative complications. METHODS We reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2008-2020) to identify patients who underwent OS for mandibular and maxillary hypo- and hyperplasia. The postoperative outcomes of interest included 30-day surgical and medical complications, reoperation, readmission, and mortality. We also evaluated risk factors for complications. RESULTS The study population included 674 patients, 48% of whom underwent single jaw surgery, 40% double jaw surgery, and 5.5% triple jaw surgery. The average age was 29 ± 11 years, with an equal gender distribution (females: n = 336; 50%, males: n = 338; 50%). Adverse events were relatively rare, with a total of 29 (4.3%) complications reported. The most common surgical complication was superficial incisional infection (n = 14; 2.1%). While the multivariable analysis revealed isolated single lower jaw surgery (p = 0.03) to be independently associated with surgical complication occurrence, it also identified an association between the outpatient setting and the frequency of surgical complications (p = 0.03) and readmissions (p = 0.02). In addition, Asian ethnicity was identified as a risk factor for bleeding (p = 0.003) and readmission (p = 0.0009). CONCLUSION Based on the information recorded by the ACS-NSQIP database, our analysis underscored the positive (short-term) safety profile of OS. We found OS of the mandible to be associated with higher complication rates. The calculated risk role of OS in the outpatient setting warrants further investigation. A significant correlation between Asian OS patients and postoperative adverse events was found. Implementation of these novel risk factors into the surgical workflow may help facial surgeons refine their patient selection and improve patient outcomes. Future studies are needed to investigate the causal relationships of the observed statistical correlations.

Abstract
Objective To systematically review the literature and assess the effectiveness of perioperative systemic and nonsystemic therapies in reducing edema after orthognathic surgery. Study Design Four databases (PubMed, Web of Science, Bireme, and Scopus) were searched. Only randomized clinical trials were included and assessed using the RoB 2.0 software (Cochrane Collaboration, London, UK). Studies were grouped into time of assessment and systemic/nonsystemic therapy. Results Eighteen studies were included in this review (8 in the meta-analysis, n = 349). The qualitative assessment of systemic (enzyme therapy, dexamethasone, betamethasone, and Venoplant) and nonsystemic therapies (thermotherapy and K-Taping) appear to reduce edema. Manual lymphatic drainage (MLD) after 72 hours (CI: -1.03 to 2.31; P = .45), and 30 days (CI: -1.53 to 0.49; P = .49), and laser after 24 hours (CI: -1.36 to 1.48; P = .93), 72 hours (CI: -4.81 to 2.92; P = .63), 30 days (CI: -3.44 to 0.99; P = .28), and 90 days (CI: -1.83 to 0.96; P = .54) showed no significance. Thermotherapy reduced edema after 48 hours (CI: -48.47 to -13.31; P = .0006) and 30 days (CI: -14.73 to -1.98; P = .01). Conclusion The Grading of Recommendations, Assessment, Development and Evaluations tool showed moderate evidence for thermotherapy (significant reduction of edema), whereas the MLD and laser results were rated as high certainty of evidence (no reduction of edema).

Abstract
INTRODUCTION Facial transplantation has emerged as a viable option in treating devastating facial injuries.Despite the high healing rate of Le Fort III and bilateral sagittal split osteotomies (BSSO) in nontransplant patients, few studies have reported assessment of maxillary and mandibular healing in face transplant patients compared with nontransplant patients. The aim of this study was to examine differences in bone healing in our patients. PATIENTS AND METHODS A retrospective chart review was conducted of facial allotransplantation patients at the Cleveland Clinic from December 2008 to inception. Demographics such as age, date of birth, and sex were recorded. Additional variables included procedures, revisions, reoperations, medications, and bone stability and healing. Computed tomography (CT) images assessed the alignment of skeletal components, bony union quality, and stability of fixation. RESULTS Three patients were included: 2 had Le Fort III segment transplantation, and 1 had transplantation of both a Le Fort III segment and mandibular BSSO. The Le Fort III segment in all patients exhibited mobility and fibrous union at the Le Fort III osteotomy on CT. In contrast, the BSSO healed uneventfully after transplantation and revision surgery, with bony union confirmed by both CT and histology of the fixation area between the donor and recipient mandible bilaterally. No patients with midfacial fibrous union required revision of the nonunion as they were clinically asymptomatic. CONCLUSION Le Fort osteotomy demonstrates inferior healing in facial transplantation compared with the nontransplant population. In contrast, the successful healing in the mandible is likely owing to the high density of rich cancellous bone.

Abstract
PURPOSE This study aimed to evaluate the risk factors for surgical site infection (SSI) after orthognathic surgery, focusing on the duration of prophylactic antibiotic administration in Japan. STUDY DESIGN The study included 181 patients who underwent orthognathic surgery at the Department of Oral and Maxillofacial Surgery of Yamagata University Hospital between 2012 and 2021. The clinical parameters of SSI were retrospectively investigated using patient charts. Logistic regression analysis was used to estimate the odds ratios (ORs) with 95% confidence intervals (CIs) for risk factors for SSI after orthognathic surgery. RESULTS Nineteen patients (10.5%) were complicated with SSI. Male sex (OR, 3.638; 95% CI, 1.316-10.058) and an antibiotic prophylaxis duration ≤3 days (OR, 12.718; 95% CI, 1.639-98.673) were independent risk factors for SSI after orthognathic surgery. CONCLUSION Extended-term antibiotic prophylaxis was more effective for prevention of SSI after orthognathic surgery than short-term in this study.

Determining Morbidity of Adding Genioplasty to Bimaxillary Orthognathic Surgery. Aesthetic Plast Surg 2022; 47:1104-1110.

Abstract
BACKGROUND Patients with dentofacial anomalies may undergo orthognathic surgery to address functional and aesthetic concerns. Past works have evaluated determinants affecting length of stay (LOS) in patients undergoing upper and/or lower jaw surgery alone. No studies have assessed the addition of genioplasty to double-jaw (Lefort I, bilateral sagittal split osteotomy (BSSO))) surgery and its effect on LOS and other outcomes. This study investigates whether the addition of genioplasty incurs additional morbidity to patients undergoing complex orthognathic surgery. METHODS This was a retrospective cohort study of patients undergoing orthognathic surgery at Yale-New Haven Hospital. Clinical and demographic information were compared across the "double"- and "triple"-jaw cohorts with t tests and Chi-squared analyses. Multivariable linear and logistic regression analyses were utilized to assess the impact of genioplasty when controlling for baseline patient differences. RESULTS A total of 27 patients received Lefort I and BSSO (double-jaw), and 224 received Lefort I, BSSO, and genioplasty (triple-jaw). Six (22.2%) double-jaw patients were segmental and fifty-eight (25.9%) triple-jaw patients were segmental (p > 0.05), during the study period. Triple-jaw surgery was associated with increased operative time (+ 41.1 min, p < 0.01). There was no increase in LOS, postoperative nausea and vomiting, opioid use, hematoma, or infection (p > 0.05). CONCLUSIONS This study attempted to determine if triple-jaw surgery could influence patients' LOS and other surgical outcomes compared to double-jaw surgery. Only the operative time was significantly affected. This indicates that incorporation of a genioplasty can provide aesthetic benefit without incurring significant additional morbidity to the patient.

Abstract
Background: Bimaxillary orthognathic surgery bears the risk of severe postoperative airway complications. There are no clear recommendations for immediate postoperative follow-up and monitoring. Objective: to identify potential risk factors for prolonged mechanical ventilation and delayed extubation in patients undergoing bimaxillary orthognathic surgery. Methods: The data of all consecutive patients undergoing bimaxillary surgery between May 2012 and October 2019 were analyzed in a single-center retrospective cohort study. The clinical data were evaluated regarding baseline characteristics and potential factors linked with delayed extubation. Results: A total of 195 patients were included; 54.9% were female, and the median age was 23 years (IQR 5). The median body mass index was 23.1 (IQR 8). Nine patients (4.6%) were of American Society of Anesthesiologists Physical Status Classification System III or higher. The median duration of mechanical ventilation in the intensive care unit was 280 min (IQR, 526 min). Multivariable analysis revealed that premedication with benzodiazepines (odds ratio (OR) 2.60, 95% confidence interval (0.99; 6.81)), the male sex (OR 2.43, 95% confidence interval (1.10; 5.36)), and the duration of surgery (OR 1.54, 95% confidence interval (1.07; 2.23)) were associated with prolonged mechanical ventilation. By contrast, total intravenous anesthesia was associated with shorter ventilation time (OR 0.19, 95% confidence interval (0.09; 0.43)). Conclusion: premedication with benzodiazepines, the male sex, and the duration of surgery might be considered to be independent risk factors for delayed extubation in patients undergoing bimaxillary surgery.

Abstract
Background: The present study aims to compare the accuracy of jaw repositioning in bimaxillary orthognathic surgery using digital surgical planning in cleft lip and palate patients and in non-syndromic skeletal class III patients in order to investigate if orthognathic surgery achieves different results in the first group of patients. Method: This study included 32 class III adult patients divided into 2 groups: cleft lip and palate (A, n = 16) and non-cleft (B, n = 16). For each patient, a 2D pre-surgical visual treatment objective was performed by the surgeon to predict hard tissue changes, and the surgical outcome was compared with that planned by using cephalometric measurement (ANB, SNA, SNB, Ar-Go-Me, S-Ar-Go). The statistical analysis showed equivalence between obtained and planned results for each measurement both in group A and in group B, but the difference between the planned and the obtained result was smaller in group B regarding ANB angle. Conclusions: Digital surgical planning ensures better predictability of the surgical results and higher accuracy of surgery in complex patients, such as those with cleft lip and palate.

Abstract
Orthognathic surgery is generally a safe and predictable procedure. Major postoperative complications are rare and often non-life threatening. An example of a rare complication associated with the LeFort I osteotomy is avascular necrosis of the maxilla (ANM). While cases of ANM have been described in the literature, the majority involves only a portion or segment of the maxillary complex and is commonly treated with conservative measures such as strict oral hygiene, hyperbaric oxygen therapy and local debridement. Occasionally, larger segments of osteonecrosis may require extensive reconstruction such as bone grafting with local soft tissue flaps. Here, we present a patient that underwent a single-stage microvascular free tissue reconstruction with concomitant placement of dental implants and a patient-specific implant (PSI) for post-orthognathic ANM.

Maxillofac Plast Reconstr Surg 2022; 44:7. [PMID: 35212834 PMCID: PMC8881570 DOI: 10.1186/s40902-022-00336-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 02/07/2022] [Indexed: 11/28/2022] Open
Abstract
Background Excessive bleeding is a major intraoperative risk associated with orthognathic surgery. This study aimed to investigate the factors involved in massive bleeding during orthognathic surgeries so that safe surgeries can be performed. Patients (n=213) diagnosed with jaw deformities and treated with bimaxillary orthognathic surgery (Le Fort I osteotomy and bilateral sagittal split ramus osteotomy) in the Department of Oral and Maxillofacial Surgery at the Suidobashi Hospital, Tokyo Dental College between January 2014 and December 2016 were included. Using the patients’ medical and operative records, the number of cases according to sex, age at the time of surgery, body mass index (BMI), circulating blood volume, diagnosis of maxillary deformity, direction of maxillary movement, operative duration, incidence of bad split, injury of nasal mucosa, and blood type were analyzed. Results The results revealed that BMI, circulating blood volume, nasal mucosal injury, and operative time were associated with the risk of intraoperative massive bleeding in orthognathic surgeries. Chi-square tests and binomial logistic regression analyses showed significant differences in BMI, circulating blood volume, direction of maxillary movement, operative duration, and injury to the nasal mucosa. Operative duration emerged as the most important risk factor. Furthermore, a >4-mm upward migration of the posterior nasal spine predicted the risk of massive bleeding in orthognathic surgery. Conclusions The upward movement of the maxilla should be recognized during the preoperative planning stage as a risk factor for intraoperative bleeding, and avoiding damage to the nasal mucosa should be considered a requirement for surgeons to prevent massive bleeding during surgery.

Abstract
PURPOSE The surgical condylar displacement often resulted in relapse and serious symptoms of temporomandibular joint disorders (TMD) after orthognathic surgery. To minimize the displacement, numerous techniques have been proposed. To verify their accuracy in positioning and effectiveness in preventing postoperative TMD and relapse, we reviewed the literature related to intraoperative condylar positioning techniques on the mandible in this study. METHODS The literature on condylar positioning techniques was reviewed with 2 charts, including the non-computer-assisted and the computer-assisted positioning methods. The pre- and postoperative alterations of condyles, the postoperative temporomandibular joint (TMJ) function, and surgical relapse were analyzed regarding the techniques. The clinical usage and characteristics were reviewed as well. RESULTS A total of 22 articles, including 907 patients, have been reported since 2001. Nearly all methods reach a considerable positioning accuracy within the range of 1-2 mm and 1-2° from the preoperative position. We ranked the accuracy of the methods from high to low: CAD/CAM CPDs>CAD/CAM titanium plate positioning>manual positioning>computer-assisted navigation systems>imaging positioning systems. Most skeletal class II and class III patients achieved great occlusion and had no TMJ dysfunction or relapse after condylar positioning. CONCLUSION Both the non-computer-assisted and computer-assisted condylar positioning techniques reach considerable accuracy in locating the preoperative condyle position and preventing TMJ dysfunction and surgical relapse. Different levels of surgeons and cases can benefit from multiple suggested positioning methods. Further research with large samples and long-term follow-up is worth looking forward to upgrading the current methods, improving the clinical utility, and developing new positioning techniques.

Abstract
ABSTRACT Bilateral sagittal split osteotomy is a routine procedure with predictable andwell-known complications. The authors report a thitherto unreported complication of bilateral sagittal split osteotomy presenting as a postoperative sialocele of submandibular salivary gland tissue in the floor of the mouth. The sialocele was probably caused by overinstrumentation and injury to sublingual salivary tissues or Wharton's duct during bicortical drilling or screw fixation. This iatrogenic sialocele was managed conservatively with multiple aspiration and compression dressings. Although rare and unreported so far this complication may be included in the preoperative consent process.

Abstract
This article aimed to review adverse events and complications to orthognathic surgery based upon 10 years. This study was a retrospective investigation between 2009 and 2018. Independent variables such as sex, age, pre-operative conditions, diagnosis, type of surgery, bleeding volume, surgery duration, and hospitalization were recorded. The data regarding orthognathic surgery adverse events and complications were evaluated and statistically analyzed with a significance level of p < 0.05. A total of 891 patients were included in this study (male 39.1%, female 60.9%) with a mean age of 26.4 ± 6.09 years. A neurosensory disturbance was found as immediate post-operative sequelae as 93.5%. The four most frequent complications had a relapse (6.4%), post-operative TMD (5.7%), unfavorable osteotomy (5.5%), and infection (4.9%), which seem to be more common in males. An average blood loss was 497 ± 371 ml and the average operative time was 401 ± 109.3 min. Complication rates were statistically affected by bleeding volume (p-value = 0.01), operative time (p-value = 0.03), and type of skeletal deformity (p-value = 0.01). Although numerous complications were recorded, no fatal complications were experienced. Bleeding time, operative time, and skeletal classification have significant influence on orthognathic surgery complications. However, a multitude of factors could be modified to reduce the complication rate and improve the result of the treatment. One of the most significant factors was the operative time.

Abstract
This study investigated the relationship between the thickness of the ramus and skeletal patterns using cone-beam computed tomography (CBCT) for sagittal split ramus osteotomy. Ninety participants were categorized into three skeletal patterns (Class I, Class II, and Class III). The first vertical slice (slice 0) was observed in the intact mandibular canal, and then moved forward to 40 mm (slice 21) with a 2 mm interval. The thickness of buccal bone marrow (B value) was measured. A B value of ≤0.8 mm was considered to be the major risk factor causing the occurrence of postoperative lower lip paresthesia. There were 461 sides with a B value of ≤0.8 mm. There was a significant difference in the skeletal patterns [Class III (198 sides: 15.7%) > Class I (159 sides: 12.6%) > Class II (104 sides: 8.3%)]. Class II participants had significantly larger B values (2.14 to 3.76 mm) and a lower occurrence rate (≤0.8 mm) than those of Class III participants (1.5 to 3 mm) in front of the mandibular foramen (from 6 mm to 20 mm). Class III participants had significantly shorter buccal bone marrow distance and a higher occurrence rate of B values (≤0.8 mm) than Class II.

Abstract
The goal of this study was to evaluate the incidence of postoperative wound infection and timing of mandibular third molar removal in bilateral sagittal split osteotomy (BSSO). This wis a prospective, single-blinded, randomized, split-mouth clinical trial. All patients were divided into two groups: Group I, where pre-operative removal of the third molars were done 6 months prior to BSSO and Group II, where intra-operative removal of contralateral third molars were done for the same patients during the osteotomy. The primary outcome variable studied was postoperative infection rate and the secondary outcome variable was bad split during BSSO. Among the seventy five patients (150 sites), one site in group II developed infection whereas none of the sites in group I developed infection (p = 1.000). No sites had bad split in both the groups. The results from the present study show that there is no difference between the presence or absence of mandibular third molars on post-operative wound infection following bilateral sagittal split osteotomy, and the authors hence suggest removing third molars during BSSO for patient comfort.

Abstract
PURPOSE Maxillomandibular advancement (MMA) is an accepted treatment modality for obstructive sleep apnea. The purpose of this study was to evaluate the incidence of complications requiring an intensive care unit (ICU) level of care and the necessity of routine overnight ICU airway monitoring after MMA. PATIENTS AND METHODS This was a retrospective cohort study of patients undergoing MMA at Massachusetts General Hospital from 2003 to 2020. The primary predictor variable was postoperative admission to the ICU versus post anesthesia care unit (PACU) or ward. The primary outcome variable was grade IV or V complications as scored using the Clavien-Dindo classification system. The secondary outcome variables included postoperative SpO2 nadir and length of hospital stay. Descriptive and bivariate statistics were computed to measure the association between complications and predictor variables. RESULTS The study sample consisted of 104 patients (74.0% male, mean age 37.6 ± 12.1 years), 61 of whom were admitted to the ICU (58.7%). During the initial 24 hours of airway monitoring, the mean SpO2 nadir was 93.7 ± 2.59% for patients admitted to the ICU compared with 94.0 ± 6.56% for patients admitted to the PACU or ward (P = .862). Patients experienced 2 grade IV complications (1.92%) and no grade V complications, with no statistical association between complications and postoperative admission location (P = 1.000). Age (P = .002) and operative time (P = .046) were the only variables statistically associated with grade IV or V complications. There was no difference in length of hospital stay between patients admitted to the ICU (2.64 ± 1.37 days) versus PACU or ward (2.58 ± 1.62 days). CONCLUSIONS The incidence of complications requiring ICU-level care after MMA for obstructive sleep apnea is low. Additional studies are warranted to guide development of feasible, cost-effective perioperative protocols for patients undergoing MMA.

Abstract
The aim of this study was to investigate whether the bone marrow space volume of the mandible affects blood loss during bilateral sagittal split osteotomy (BSSO). Sixteen patients who underwent BSSO in our hospital were included in this study. Bone marrow space volume of the mandible was measured by analyzing images from computed tomography. Blood loss during BSSO was measured by weighing gauze, measuring suctioned blood, and adjusting for the volume of irrigation solution used during BSSO. Mean blood loss during BSSO for the 16 patients was 200.5 ml, and patients were divided into: Group I, with less than mean blood loss; and Group II, with greater than mean blood loss. Total bone marrow space volume was significantly greater in Group II (12,450.7 ± 2644.3 mm3) than in Group I (9130.3 ± 3005.8 mm3; P<0.05). A correlation between bone marrow space volume and blood loss during BSSO was suggested, and these results are beneficial for surgeons planning and preparing the orthognathic surgery.

Abstract
ABSTRACT Anterior maxillary osteotomy is a traditional operation in the treatment of maxillary protrusion. Varies fields about operation have been changed or improved in those years to avoid different kinds of complications. In our study, the authors would present 1 kind of improved anterior maxillary osteotomy surgical method. The study was conducted at the Department of Oral and Maxillofacial Surgery, Guanghua School of Stomatology, Hospital of Stomatology, Guangzhou, Guangdong province. Patients are divided into improved group and general group. Patients after surgery were claimed to have regular return visits. Occlusion, tooth vitalities, postoperative complications would be well evaluated. The operative time, blood losses, complications showed no different at maxillary operation. Our procedure could give much better and direct sight of anterior maxillary bone, and the simplified osteotomy lines could help maxilla move, reduce the times spent on hard tissue cut off or grind. The modified procedure can meet clinical command, improve dentofacial deformities, and gives convenience to surgeon.

Abstract
PURPOSE Perioperative outcomes following cleft orthognathic surgery are not well established. The purpose of this study was to compare the incidence of orthognathic specific complications (OSCs) in patients with and without cleft lip and/or palate. METHODS The American College of Surgeons National Surgical Quality Improvement Program adult and pediatric databases were used to enroll patients undergoing orthognathic surgery. The primary predictor variable was a prior diagnosis of cleft lip and/or palate: cleft versus noncleft. The primary outcome variable was OSCs (yes/no) within 30 days of the index operation. Descriptive, bivariate, and multiple logistic regression statistics were computed to measure the association between cleft status and OSCs. RESULTS The study sample was composed of 1,149 subjects: 98 in the cleft group and 1,051 in the noncleft group. The incidence of OSCs was 6.1 and 4.7% for the cleft and noncleft groups, respectively (P = .461). After adjusting for age, cleft status, bone grafting, segmentation of the maxilla, and history of bleeding disorder, classification as American Society of Anesthesiologists (ASA) III (P = .002, odds ratio [OR] = 3.92, 95% confidence interval [CI] 1.63-9.40), ASA IV (P = .039, OR = 9.47, 95% CI 1.12-80.4), and isolated mandibular osteotomies (P = .006, OR = 3.23, 95% CI 1.40-7.48) were independent predictors of OSCs. Length of stay was 1.66 ± 1.14 days compared to 1.37 ± 3.74 days for the cleft and noncleft groups, respectively (P = .443). CONCLUSIONS There was no significant difference in the incidence of perioperative OSCs and length of hospital stay between cleft and noncleft patients. Cleft status was not an independent predictor of OSCs; instead, greater ASA classification and isolated mandibular osteotomies were the only predisposing factors. Patients with clefts undergoing orthognathic surgery do not have an increased risk of short-term OSCs within the limitations of this study.

Abstract
PURPOSE Patients with significant dentofacial deformities undergoing aesthetic and functional orthognathic surgery may often require genioplasty to advance the position of the pogonion relative to B point. No study to date has evaluated nationally registered data pertaining to addition of osseous genioplasty to bimaxillary orthognathic surgery and its associated clinical outcomes. METHODS Data was extracted from the National Surgical Quality Improvement Program from 2010 to 2018 using current procedural terminology codes pertaining to Le Fort I osteotomy (LF), bilateral sagittal split osteotomy (BSSO), and osseous genioplasty (G) and divided into 2 cohorts: bimaxillary orthognathic surgery with and without osseous genioplasty. Thirty-day postoperative outcomes inherently recorded within National Surgical Quality Improvement Program were identified and recorded. Chi-squared analysis and unpaired 2-tail t tests were performed between the cohorts and their respective outcomes to determine significant relationships with significance set as P < 0.05. RESULTS There were 373 patients double- or triple-jaw patients identified from the years 2010 to 2018. The most common recorded indication for LF/BSSO was maxillary hypoplasia (27.3%) and mandibular hypoplasia (6.8%). The most common indications for LF/BSSO/G were maxillary hypoplasia (16.1%) and maxillary asymmetry (16.1%). In comparison to LF/BBSO only, LF/BSSO/GP was not associated with any differences in the rate of surgical (0.0% versus 0.31%, P = 0.72) or medical complications (0.0% versus 0.63%, P = 0.60), in addition to unplanned readmissions (0.0% versus 1.56% versus P = 0.41) or reoperations (0.0% versus 1.25%, P = 0.46). However, osseous genioplasty addition was associated with increased overall operating time (271.77 versus 231.75 minutes, P = 0.04). CONCLUSIONS Osseous genioplasty does not alter short-term, 30-day complication rate when performed with bimaxillary orthognathic surgery. As reoperation rates remained relatively unchanged, it can be inferred that immediate adverse events or patient dissatisfaction were not apparent within 30 days. Although mean operating time is slightly longer, cardiopulmonary resuscitation without medical comorbidity was achieved at the conclusion of the procedure.

Abstract
OBJECTIVE To provide information about complication rates and the risk factors for complications with mandibulectomy and maxillectomy procedures in dogs. ANIMALS 459 client-owned dogs that underwent a mandibulectomy or maxillectomy between January 1, 2007, and January 1, 2018. PROCEDURES Inclusion criteria included a complete medical record that contained an anesthesia record, surgical report, available histopathology results, and results of CBC and serum biochemical analysis before surgery. A minimum follow-up of 90 days after surgery was required. RESULTS 271 complications occurred in 171 of 459 (37.3%) dogs. Eighteen complications were not given a severity description. Of the remaining 253 complications, most were considered minor (157/253 [62.1%]). Multivariable logistic regression analysis revealed that only increased surgical time had a significant (OR, 1.36; 95% CI, 1.12 to 1.54) association with the occurrence of ≥ 1 complication. For each additional hour of surgery, the odds of complications increased by 36%. Preoperative radiation therapy or chemotherapy increased the odds of incisional dehiscence or oral fistula formation (OR, 3.0; 95% CI, 1.3 to 7.2). Additionally, undergoing maxillectomy, compared with mandibulectomy, increased the odds of incisional dehiscence or oral fistula formation (OR, 1.8; 95% CI, 1.1 to 3.1). Two hundred forty-four of 271 (90.0%) complications occurred in the perioperative period (0 to 3 months after surgery). CONCLUSIONS AND CLINICAL RELEVANCE Compared with mandibulectomy, performing maxillectomy increased the risk for incisional dehiscence or oral fistula formation. Mandibulectomy and maxillectomy had a moderate risk for a complication.

Abstract
Objectives The aim of this study was to determine Relapse and TMD as postoperative complication in skeletal class III patients undergoing bimaxillary orthognathic surgery. Materials and methods Data was obtained by database searching using The Cochrane Central Register of Controlled Trials (central), PUBMED, SCOPUS, EMBASE, Google scholar, National Medical library, New Delhi. The titles and abstracts of the electronic search results were screened and evaluated by two observers for eligibility according to the inclusion and exclusion criteria. Results 5261 articles were retrieved for the review. Among these, 3474 duplicate articles were removed. 418 studies were selected based on the eligibility criteria. For the present review, 30 articles were included after elimination according to the inclusion criteria. The Prisma diagram flowchart demonstrates our selection scheme. Quality assessment criteria to evaluate the studies were decided by two review authors in accordance with CONSORT guidelines. Each study was assessed using the evaluation method described in the Cochrane Handbook for Systematic Reviews. Among the 30 studies included in the review, marked degree of relapse in the mandible was noted from 3 months - 1 year postoperatively in 8 studies, 5 studies reported both TMD prevalence and relapse, whereas only 4 studies reported TMD disorder alone. Conclusion Complications of relapse and TMD are associated with bimaxillary orthognathic surgery procedures. More RCTs and CCTs are needed in this regard to get better quality evidence. This review was registered with PROSPERO: CRD42020211342.

Abstract
The aim of this study was to evaluate the position of the mandibular canal (MC) before and after bilateral sagittal split ramus osteotomy (BSSRO) using cone-beam computed tomography (CT), and to compare the position of the MC in Class II and Class III patients in the preoperative period. Patients were divided into two groups: Class II (n = 38) and Class III (n = 41). Measurements of the superior, inferior, buccal, and lingual distances of the MC in relation to the cortical bone were taken at three levels in the proximal segment of the mandible. Results were analysed using the Kruskal-Wallis test (p < 0.05). In the Class II group the superior distance of the MC at levels 2 and 3, and the inferior distance at level 3 significantly decreased after BSSRO. In the Class III group, no significant differences were found at any level, and the inferior distances at all levels were smaller preoperatively than those in the Class II group. In the Class II group the position of the MC altered in relation to superior and inferior cortical bone after BSSRO. However, the position of the MC remained stable in the Class III group. Our results also suggest a deeper cut in inferior cortical bone in Class III patients.

Abstract
This retrospective study was performed to report the peri- and postoperative complications encountered by patients who underwent Le Fort I osteotomy, as well as predictor variables affecting the risk of complications. Patients who underwent only Le Fort I osteotomy were included in the study. Information on peri- and postoperative complications were collected from the patient data records. The effects of certain predictor variables on complication rates were also studied. Twenty-four per cent of the patients suffered from complications, six (6.1%) of whom were reoperated. Most of the complications were minor and transient. Compared with one-piece osteotomy, segmental osteotomy was a significant risk factor predisposing patients to postoperative complications (p = 0.04619). Additionally, the use of patient-specific implants seemed to increase the risk of both perioperative and postoperative complications (p = 0.0248). Currently, the conventional plate fixation method is the primary method in Le Fort I osteotomies. Careful patient selection, surgical planning, and selection of surgical technique seem to be the most important factors in reducing the complication risk. Special attention should be paid with segmental osteotomy surgery.

Abstract
The retrospective cohort study aimed to assess the incidence and characteristics of these complications in patients who underwent orthognathic procedures. Data on the intraoperative and the postoperative complications were extracted from the patients' medical files. Procedures were further subdivided into single-jaw procedures and bimaxillary procedures. A total of 209 orthognathic procedures were carried out in 190 patients. 184 (88%) were performed to treat angle class III malocclusion, while 25 (12%) aimed to treat class II malocclusion. A total of 94 complication events were observed (44.9% of 209 procedures). 22 of them occurred in single-jaw procedures (28.2% of 78 single jaw operations), and 72 occurred in bimaxillary procedures (55% of 131 bimaxillary operations). When compared regarding the type of complication, complication rates were comparable between the study groups with the exception of late-stage malocclusion. A significant difference (p-value = 0.028) in malocclusion incidences between the bimaxillary and single-jaw groups were observed (9 events, 4.3% and zero events, 0%, respectively). The majority of the complications during and following orthognathic surgical procedures are temporary or minor and require little or no treatment at all.

Abstract
BACKGROUND Facial asymmetry from unilateral condylar hyperplasia (UCH) may be definitively treated in the presence of active disease (with high condylectomy and concurrent orthognathic surgery) or after waiting for disease inactivity (orthognathic surgery alone). There is currently no consensus on the standard of care. In this study, we sought to compare functional and esthetic outcomes, as well as treatment duration, between these 2 management options. METHODS Patients who underwent treatment for UCH were identified through retrospective review. Pre- and postoperative 3-dimensional (3D) images were obtained. Short- and long-term operative outcomes of those treated during the active (group 1) were compared to those treated in the inactive phase (group 2). Total treatment time, operative time, and length of hospital stay were evaluated. Facial asymmetry was also assessed by laypersons using a Likert scale. RESULTS Fifteen patients (mean 25.6 years, range 14-56) were included: 6 in group 1 and 9 in group 2. All surgical outcomes were statistically independent of procedure type. Treatment time was significantly longer in the group 2 (P = 0.03). Both groups demonstrated significant improvement in facial asymmetry scores postoperatively with no significant difference in pre- or postoperative asymmetry between groups (P = 0.64). CONCLUSIONS In patients with active UCH, high condylectomy and orthognathic surgery is a procedure that restores facial symmetry and improves jaw function while halting mandibular growth. Good esthetic and functional outcomes, as well as reduced treatment time and disease burden, support the use of this treatment option for this population.

Sagittal Split Ramus Osteotomy in the Shortest Buccal Bone Marrow Distances of the Mandible on the Coronal Plane. BIOMED RESEARCH INTERNATIONAL 2021; 2021:5586498. [PMID: 33791365 PMCID: PMC7997755 DOI: 10.1155/2021/5586498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 03/02/2021] [Accepted: 03/08/2021] [Indexed: 11/17/2022]
Abstract
Purpose This study investigated the relationship between the shortest buccal bone marrow of the ramus and skeletal patterns. Materials and Methods Using cone-beam computed tomography data (specifically, the A point-nasion-B point (ANB) angle), we divided patients into three groups as follows: skeletal class I (0° < ANB < 4°), class II (ANB: ≥4°), and class III (ANB: ≤0°). Sixteen vertical sections in the coronal plane were taken starting from slice 0 (original intact mandibular canal) anteriorly at 2 mm intervals to slice 15 (30 mm). The thickness of the mandible (M) and shortest buccal bone marrow (SBM) were measured. The data of SBM were divided into two groups (SBM ≥ 1 mm and SBM < 1 mm). For each skeletal pattern, an SBM value < 1 mm was considered to indicate a high possibility of postoperative nerve paresthesia and bad split. Results The three skeletal pattern groups also did not significantly differ in their M values for all sections. The mean SBM values of class III (0.91–2.11 mm) at 6–16 mm anterior to the mandibular foramen were significantly smaller than those of class II (1.53–3.17 mm). Comparing the occurrence ratio of SBM < 1 mm, the highest and lowest probabilities in class III (55% and 21.7%, respectively) were significantly larger at 6–20 mm anterior to the mandibular foramen than those in class II (28.3% and 5%, respectively). Conclusion Class III had a significantly shorter SBM distance and higher SBM occurrence probability than class II at the mandibular ramus region, implying that class III participants are more likely than class II participants to have nerve paresthesia and bad split after sagittal split ramus osteotomy.

Abstract
Previously, in the case of malocclusion owing to skeletal discrepancy in adults, the amount of tooth movement was limited since there was no reliable skeletal anchorage device. The only way to treat this case was by repositioning the maxilla and mandible via orthognathic surgery, but most patients are reluctant to undergo surgery owing to the risk and expenses incurred. However, with the current introduction and use of miniscrews as temporary anchorage devices, the entire dental arch can be relocated to a target position without surgery, thus broadening the scope of non-surgical orthodontic treatment compared to the past. For a non-surgical approach to improve skeletal discrepancy, anteroposterior, vertical and transverse displacements of the dental arch are necessary. In this case, the localization of the centre of resistance of the whole arch must precede the appliance design with an appropriate biomechanical design. Especially, in the transverse dimension, the envelope of discrepancy is reportedly narrow, and the tooth movement must accompany the orthopaedic correction involving the midpalatal suture expansion. Recently, in adults with transverse maxillomandibular discrepancy, miniscrew-assisted rapid palatal expansion (MARPE) can be performed. Moreover, compared to surgically assisted rapid palatal expansion, MARPE reduces the cost to the patient and achieves clinically acceptable stable maxillary expansion. In this article, we will discuss the role of total arch movement and MARPE in widening the scope of non-surgical orthodontic treatment, despite the inherent limitations of miniscrews' mechanical aspects.

Abstract
Background: Technological progress has led to the transition to digital methods to perform surgical planning and to obtain surgical splints with CAD/CAM technologies. The present study aimed to compare the accuracy of jaw repositioning in bimaxillary orthognathic surgery using traditional and digital surgical planning in skeletal class III patients. Methods: This study included 60 skeletal class III patients divided into two groups based on the method used to perform surgical planning: traditional (T, n = 30) and digital (D, n = 30). For each patient, a 2D presurgical Visual Treatment Objective (VTO) was prepared and the outcome of the surgery was compared with that planned by using determined cephalometric measurements (ANB, SNA, SNB, Ar-Go-Me, S-Ar-Go). Statistical analysis showed that the measurements planned and those obtained after surgery were equivalent in Group D. For Group T, the analysis showed equivalence only for one of the considered measurements (ANB). By comparing the results of the two groups, Group D presented a lower level of error than Group T. Conclusions: Digital surgical planning performed significantly better in terms of accuracy of jaw repositioning than the traditional protocol.

Abstract
OBJECTIVE The aim of this study was to assess the quality of online information for patients on orthognathic surgery. MATERIALS AND METHODS A selection of search terms specific for orthognathic surgery was chosen and 150 websites were identified using the Internet search engines Google, Yahoo and Bing. Irrelevant websites were excluded. The remaining websites were assessed with a modified Ensuring Quality Information for Patients (EQIP) tool. EQIP evaluates the quality of medical patient information by measuring the three key aspects of content, structure, and identification data. RESULTS 48 relevant websites were identified. EQIP values ranged between 2 and 28 (median 13.65). While 37 of the 48 websites described details of the surgical procedures, only 13 mentioned possible risks and complications of the surgery. No differences were found between the websites of private practices, dentists and public hospitals, universities, or others (p = 0.66). Websites found by Google had a significantly lower EQIP score compared with Yahoo and Bing (11.12 vs. 16.60 for Yahoo and 16.23 for Bing; p = 0.012). The better the rank of the website, the higher the EQIP score (r = -0.411, p = 0.004). CONCLUSIONS The results of this study reflected a large variation of quality of information on orthognathic surgery on the Internet. Therefore, surgeons must be aware that they might be confronted with unrealistic expectations of patients, who may underestimate the potential risks and drawbacks of orthognathic surgery.
