[PMID: 38643964 DOI: 10.1016/j.joms.2024.03.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 03/27/2024] [Accepted: 03/28/2024] [Indexed: 04/23/2024]
Abstract
BACKGROUND The existing data on the link between body mass index (BMI), operative characteristics, and surgical outcomes across orthognathic surgery are limited. PURPOSE The purpose was to measure the association between BMI and early postoperative outcomes in orthognathic surgery. STUDY DESIGN, SETTING, AND SAMPLE This is a retrospective cohort study of patients (n = 118) aged > 14 years undergoing bimaxillary orthognathic surgery between 2015 and 2018 by a single surgeon within the Kaiser Permanente Northern California-integrated healthcare system. Patients undergoing unilateral or additional procedures, history of prior orthognathic surgery, or pre-existing pain conditions were excluded. PREDICTOR VARIABLE The predictor variable was BMI measured as a continuous (kg/m2) and categorical variable (underweight/normal, overweight, obese). MAIN OUTCOME VARIABLE(S) The primary outcome variables were additional postoperative antibiotics, increased postoperative visits, wound dehiscence, and wound infection. The secondary outcome variables were total operative and anesthesia time. COVARIATES The demographic covariates included age, sex, and race/ethnicity. The clinical covariates included history of obstructive sleep apnea, Mallampati score, tobacco use, American Society of Anesthesia classification, thyromental distance, history of difficult intubation, and Angle's classification. ANALYSES Bivariate and multivariate analyses were performed to measure the associations between BMI and the primary and secondary outcomes. Multivariable logistic regression analyses were used to measure associations between BMI and the postoperative outcomes. Statistical significance was defined as P < .05. RESULTS The study sample was composed of 118 subjects with a mean age of 26.91 years (standard deviation 9.43). Forty-seven percent (n = 55) were male, and the mean BMI was 25.13 (standard deviation 5.19). BMI category was significantly associated with age, with increasing age associated with higher BMI category (P = .02). According to the bivariate and multivariable logistic regression analyses, controlling for age, race/ethnicity, BMI, and total operative time, increased total operative time was associated with additional postoperative antibiotics (odds ratio = 1.03, 95% confidence interval: 1.01, 1.05), and increased postoperative appointments (odds ratio = 1.02, 95% confidence interval: 1.01, 1.04). No significant association between BMI and other clinical or operative characteristics was seen aside from American Society of Anesthesia classification. CONCLUSION AND RELEVANCE Elevated BMI was not associated with worsened operative characteristics or postoperative outcomes. This supports the suitability of orthognathic surgery in a BMI-diverse population.

Grillo R, Borba AM, da Silva YS, Brozoski MA, Miloro M, Naclério-Homem MDG. Exploring the relationship between the number of systematic reviews and quality of evidence: an orthognathic surgery-based study. Oral Surg Oral Med Oral Pathol Oral Radiol 2024; 137:101-112. [PMID: 38155010 DOI: 10.1016/j.oooo.2023.07.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 07/10/2023] [Accepted: 07/24/2023] [Indexed: 12/30/2023]
Abstract
OBJECTIVE We analyzed the quality and quantity of systematic reviews (SRs) of orthognathic surgery, the most frequently published topic in maxillofacial surgery. STUDY DESIGN We searched the PubMed database for SRs of orthognathic surgery with no restriction on the language of publication date. We assessed the certainty of evidence presented according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol and the Leiden Manifesto using the Grading of Recommendations Assessment, Development, and Evaluation approach. We analyzed the data using descriptive statistics, Pearson´s correlation test, and linear regression. RESULTS Of the 171 SRs evaluated, approximately one fifth presented evidence with a high level of certainty. The number of orthognathic surgery SRs has been increasing, and many SRs were published after very similar topics had already been published. There is no relationship between the impact factor and the certainty of evidence. CONCLUSIONS An excessive number of SRs of orthognathic surgery are published, and many SRs are superfluous, simply reporting previous findings. Clinicians should not base treatment decisions solely on the evidence presented in SRs, and journal editors and reviewers should evaluate these SRs more critically, particularly when they address topics that have already been covered in the literature.

Abstract
BACKGROUND Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). METHODS Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidence-based review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. RESULTS The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. CONCLUSION This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.

National Trends in Orthognathic Surgery: A Multi-Institutional Analysis of 6640 Patients. J Craniofac Surg 2023:00001665-990000000-00562. [PMID: 36804875 DOI: 10.1097/scs.0000000000009188] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Accepted: 10/09/2022] [Indexed: 02/22/2023] Open
Abstract
BACKGROUND LeFort I osteotomy (LF1) and bilateral sagittal split osteotomy (BSSO) have unique operative challenges and inherent anatomic considerations that predispose to certain adverse outcomes, yet their respective complication profiles continue to be debated given conflicting results from single-center investigations. The purpose of this study is to perform a multi-institutional analysis of complications, socioeconomic trends, and financial charges associated with orthognathic surgery. METHODS A retrospective cohort study was conducted of orthognathic procedures performed in the United States from 2010 through 2020 using the Pediatric Health Information System. Patients younger than 12 years of age were excluded. Medical complications, surgical complications, and admission costs were compared across procedures. Socioeconomic determinants and trends across regions of the country were also analyzed. RESULTS During the study interval, 6640 patients underwent orthognathic surgery, including LF1 (59.2%, n=3928), BSSO (14.4%, n=959), and double-jaw surgery (26.4%, n=1753). Patients undergoing LF1 were more likely to experience overall complications (P<0.001), infections (P<0.001), and blood transfusions (P<0.001) than those undergoing BSSO. High-volume hospitals were more likely to perform double-jaw procedures than other hospitals (P<0.001), yet high-volume hospitals were less likely to have surgical complications (P=0.014). Patient admission charges related to orthognathic operations at high-volume hospitals were less than other hospitals (P<0.001). Household income was higher for orthognathic procedures performed at high-volume hospitals (P<0.001). White patients were 1.5 times more likely to choose a farther, higher volume hospital for orthognathic surgery than the one locally available (P=0.041). CONCLUSIONS LeFort I osteotomy procedures had higher infection and transfusion rates than BSSO procedures. High-volume hospitals were more likely to perform double-jaw procedures, yet high-volume hospitals had fewer complications and decreased admission charges. Future study will be needed to further elucidate case-mix index details and socioeconomic determinants of health contributing to these disparities.

Abstract
INTRODUCTION This study compared the airway changes of patients with obstructive sleep apnea (OSA) after maxillomandibular advancement (MMA) with or without genial tubercle advancement (GTA) using cone-beam computed tomography. METHODS The authors retrospectively studied 26 patients with moderate to severe OSA who underwent MMA with or without GTA. Airway changes were determined from preoperative and postoperative 3-dimensional reconstructed cone-beam computed tomography images. The Wilcoxon signed rank test, Mann-Whitney U tests, and Spearman correlation coefficients were used in data analysis. RESULTS Airway was changed in all dimensions significantly after MMA with or without GTA. There was no significant difference in horizontal surgical changes between MMA and MMA with the GTA group. The mean increase in total airway volume was 66.8% for MMA alone and 74.7% for MMA with GTA (P = 0.39). Patients who underwent MMA had a larger percentage change of segmented upper airway volume than patients with MMA and GTA (106.6% vs 85.3%; P = 0.65). The group with MMA and GTA had a greater percentage change of segmented lower airway volume than the MMA alone group (80.1% vs 56.3%; P = 0.42). CONCLUSIONS Differences in airway changes between MMA alone and MMA with GTA were not statistically significant. Performing the GTA concomitantly with MMA may not cause greater improvement in the pharyngeal airway in patients with OSA compared with MMA alone.

Risk Factors for Prolonged Mechanical Ventilation and Delayed Extubation Following Bimaxillary Orthognathic Surgery: A Single-Center Retrospective Cohort Study. J Clin Med 2022; 11:jcm11133829. [PMID: 35807112 PMCID: PMC9267492 DOI: 10.3390/jcm11133829] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 06/30/2022] [Accepted: 06/30/2022] [Indexed: 11/16/2022] Open
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.

Post-Operative Patients’ Satisfaction and Quality of Life Assessment in Adult Patients with Obstructive Sleep Apnea Syndrome (OSAS). INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19106273. [PMID: 35627810 PMCID: PMC9141812 DOI: 10.3390/ijerph19106273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 05/18/2022] [Accepted: 05/19/2022] [Indexed: 01/27/2023]
Abstract
Background: The treatment for severe OSAS includes maxillomandibular advancement surgical option in selected cases. The aim of this study was to evaluate the post-operative impact of bimaxillary surgery on satisfaction and consequently the quality of life of these patients. Methods: This study included 18 patients with severe OSAS who received maxillomandibular advancement surgery. Patients were divided into Group A (operated by CAD/CAM) and Group B (conventional surgery). The impact of bimaxillary surgery on satisfaction and quality of life of these patients was evaluated by utilizing post-operative life quality and Rustemeyer’s patient-satisfaction-based survey. Results: A total of 18 adult OSAS patients (Group A: 11 patients, Group B: 7 patients) with a mean age of 44.39 years (SD ± 9.43) were included. Mean follow-up period was 32.64 months (SD ± 21.91). No intra-operative complications were seen in any patients. Post-operative complication was seen in one patient and the mandible did not integrate. According to the results, overall post-operative satisfaction score was 79.72% (SD ± 9.96). There was no significant difference among those in Group A and Group B. Conclusion: Maxillomandibular advancement surgery seems to be beneficial in terms of patients’ satisfaction in severe adult OSAS patients and can be considered as a valuable option in selected cases.

Abstract
Lack of evidence exists related to the three-dimensional (3D) pharyngeal airway space (PAS) changes at follow-up after isolated bilateral sagittal split osteotomy (BSSO) advancement surgery. The present study assessed the 3D PAS changes following isolated mandibular advancement at a follow-up period of 1 year. A total of 120 patients (40 males, 80 females, mean age: 26.0 ± 12.2) who underwent BSSO advancement surgery were recruited. Cone-beam computed tomography (CBCT) scans were acquired preoperatively (T0), immediately following surgery (T1), and at 1 year of follow-up (T2). The volume, surface area, and minimal cross-sectional area (mCSA) of the airway were assessed. The total airway showed a 38% increase in volume and 13% increase in surface area from T0 to T1, where the oropharyngeal region showed the maximum immediate change. At T1−T2 follow-up, both volumetric and surface area showed a relapse of less than 7% for all sub-regions. The mCSA showed a significant increase of 71% from T0 to T1 (p < 0.0001), whereas a non-significant relapse was observed at T1−T2 (p = 0.1252). The PAS remained stable at a follow-up period of 1 year. In conclusion, BSSO advancement surgery could be regarded as a stable procedure for widening of the PAS with maintenance of positive space at follow-up.

Abstract
PURPOSE This study aimed to evaluate the sequential changes in the pharyngeal airway dimensions after mandibular setback surgery and to verify its correlation with postsurgical mandibular stability in patients with mandibular prognathism. PATIENTS AND METHODS This retrospective study included 28 patients with mandibular prognathism who underwent surgical orthodontic treatment and isolated mandibular setback surgery. Patients who had cone-beam computed tomography before surgery, immediately after surgery, at short-term follow-up (11.8 ± 5.1 months), and long-term follow-up (43.0 ± 13.1 months) were included. Airway dimensions, including distance, minimum cross-sectional area, and airway volume, were measured to evaluate the changes following mandibular setback surgery. With the measurements of postsurgical mandibular relapse, the relationship between sequential changes in airway dimensions and the mandible was verified using correlation analysis. RESULTS Airway dimensions decreased immediately after mandibular setback surgery. The decreased airway dimensions recovered during short-term follow-up and maintained to the long-term follow-up. The mandible was set back 7.7 ± 5.1 mm at pogonion immediately after surgery. Postsurgical skeletal relapse was 1.1 mm at pogonion during short-term follow-up. During long-term follow-up, the mandible moved 0.4 mm anteriorly, which was about 50% of the changes during short-term follow-up. Statistically significant correlations were found between the sequential changes in airway dimensions and the postsurgical skeletal relapse. CONCLUSION The decreased airway dimensions following mandibular setback surgery recovered during short-term follow-up and maintained to the long-term follow-up. Dimensional recovery of the pharyngeal airway was correlated with postsurgical skeletal relapse during the 1-year follow-up period.

Abstract
Interdisciplinary treatment for patients with Treacher Collins syndrome is challenging because of the rarity of the condition and the wide variety of phenotypic expression. A 23-year-old male was diagnosed with Treacher Collins syndrome with a history of severe obstructive sleep apnea. He presented with a Pruzansky-Kaban classification grade I mandible, skeletal type II pattern with a hyperdivergent mandibular plane, severe convex profile, and Class II malocclusion with a missing mandibular incisor. Improvement of facial esthetics was achieved by a combination of orthodontics, mandibular distraction osteogenesis, and 2-jaw maxillomandibular advancement surgery. Presurgical orthodontic treatment involved permanent tooth extraction to relieve severe crowding, and Class III mechanics were employed to increase overjet. Correction of mandibular hypoplasia by increasing ramal height and the mandibular length was done by intraoral mandibular distraction osteogenesis. Counterclockwise rotation of the mandibular plane angle and a Class III occlusion with negative overjet were achieved after mandibular distraction osteogenesis. A postdistraction posterior open bite was maintained with a biteplane during the consolidation period. Subsequently, 2-jaw orthognathic surgery was performed. LeFort I osteotomy was done for maxillary advancement to correct an anterior crossbite, eliminate canting, and reestablish occlusal contact at the mandibular occlusal plane. Bilateral sagittal split ramus osteotomy was done to correct the residual mandibular deviation. A genioplasty was also performed to improve chin projection. Postoperatively, the oropharyngeal airway was enlarged. The patient's facial profile and obstructive sleep apnea problem were improved as a result of advancement and counterclockwise rotation of the maxillomandibular complex.

Abstract
PURPOSE Evaluate the impact of counterclockwise rotation of the occlusal plane (CCWROP) on pharynx morphology and polysomnography in maxillomandibular advancement (MMA) surgery to treat obstructive sleep apnea (OSA) patients. METHODS Prospective clinical trial of patients with OSA treated by MMA. Computed tomography and polysomnography were performed pre- and postoperatively and the parameters were compared. The surgery classified the patients into two groups: with (R) and without (NR) CCWROP. RESULTS The study sample comprised 38 individuals: R (n = 19) and NR (n = 19). An anterior mandible advancement of 0.71 mm was identified for each degree of CCWROP (p < 0.001). As for polysomnography, the apnea-hypopnea index was reduced by 80% and 62% in R and NR, showing final values of 6.8 and 13.0, respectively. The apnea index changed equally in both groups. Reduction of 68 and 26% in the hypopnea index was observed for R and NR, respectively, with no statistically significant difference. Total volume increased by 45% in R and 30% in NR. Retropalatal and retrolingual volumes increased by 49% and 4% in R and 43% and 15% in NR, respectively. The minimum axial area increased by 92% in the retropalatal region and 97% in the retrolingual region in R, whereas these increases were of 76% and 31% in NR, respectively. CONCLUSION Anterior mandibular advancement of 0.71 mm for each degree of CCWROP is of great importance for surgical planning. As a result of this resource, individuals in R presented better results than those in NR in all parameters assessed, especially regarding the retrolingual region.

Abstract
This study aimed to analyze pharyngeal airflow characteristics and their relationship with the skeletal movement of the maxilla and mandible after bimaxillary orthognathic surgery in patients with skeletal class III (mandibular prognathism) malocclusion. Cone-beam computed tomography (CBCT) was conducted before surgery (T0), immediately after surgery (T1), and at least six months after surgery (T2). Digital imaging and communications in medicine files were transferred to InVivo (Anatomage) software to measure the skeletal changes after surgery. The changes in the maxillary and mandibular position, tongue position, and hyoid bone position were analyzed. Patient-specific models were reconstructed using 3D-Doctor software. The models after converting to the stereolithography (STL) file for Ansys integrated computer engineering and manufacturing code for computational fluid dynamics (ICEM CFD), commercial software were used for calculating the geometry, pressure drop and adjusted pressure coefficient value. The total volume of the upper airway including nasal cavity was reduced by 23% immediately after surgery and recovered to 92.2% of the initial volume six months after surgery. The airflow computation analysis showed a decrease in the pressure drop values immediately after surgery and six months after surgery. The adjusted pressure coefficients were slightly different but the change was statistically insignificant. The airflow characteristics computed using the computational fluid dynamics were correlated to the surgical changes. The surgical changes can affect the aerodynamics of the pharyngeal airway. In clinical practice, this knowledge is useful for developing a suitable orthognathic surgery treatment plan.

Abstract
The purpose of this retrospective study was to evaluate the correlation of maxillomandibular advancement (MMA) and airway volume changes in patients with obstructive sleep apnea (OSA), and to determine the surgical skeletal movements necessary to achieve an increase in total airway volume (TAV) of ≥70%. Thirty patients with OSA treated by MMA were evaluated. Pre- and postoperative cone beam computed tomography images were used to determine the horizontal distance and angular changes in surgical parameters and linear, area, and volumetric airway parameters. Postoperatively, the horizontal distance of surgical parameters (A-point, UI, B-point, pogonion, and menton) and craniofacial angulation (SNA and SNB) increased significantly, similar to total surface area, TAV, and minimum cross-sectional area of the airway (p<0.0001). The total airway length decreased significantly (p<0.0001). The mean increase in TAV was 67.2%. There were positive correlations between linear surgical changes and the percentage change in TAV. All surgical parameters were predictive of a change in TAV ≥70%. The optimal surgical change was 6mm for A-point, 7.9mm for UI, 7.6mm for B-point, 11.2mm for pogonion, and 10mm for menton. In conclusion, maxillary advancement of less than 10mm was adequate in this study to obtain an increase in the TAV of at least 70%.

An Evaluation Using the STOP-BANG Questionnaire. J Oral Maxillofac Surg 2020; 78:2061-2069. [PMID: 32763149 DOI: 10.1016/j.joms.2020.07.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 06/15/2020] [Accepted: 07/01/2020] [Indexed: 01/08/2023]
Abstract
PURPOSE The aim of this study was to assess the impact of isolated mandibular setback surgery on the risk of obstructive sleep apnea (OSA), using the STOP-BANG questionnaire (SBQ). PATIENTS AND METHODS The authors implemented a double-blinded prospective quasi-experimental study. All healthy patients with skeletal Class III deformity older than 18 years were included in this study. They were candidates for isolated mandibular setback surgery. The SBQ was completed by the pulmonologist, 1 week preoperatively (T0), and 1 and 6 months postoperatively (T1 and T2, respectively). The mandibular setback displacement was the study intervention. The risk of OSA on the basis of the SBQ was the outcome variable. Descriptive and bivariate statistics were computed and the significance level was set at .05. RESULTS The sample comprised 30 patients (15 females, 15 males) with the average age of 25.77 ± 4.76. The mean score of SBQ at T0 was 1.37 ± 0.85, which increased to 2.33 ± 1.52 at T1 interval. However, it decreased significantly to 1.47 ± 1.17 at T2 interval (P < .001). T0-T1 and T0-T2 score differences were observed to be higher in the group with a mandibular setback repositioning greater than or equal to 5 mm (P < .005). CONCLUSIONS An isolated mandibular setback surgery less than 5 mm does not increase the risk for OSA in a young healthy nonsmoker Class III patient, according to the SBQ. Moreover, there was a significant increase in the risk for OSA when the setback was greater than or equal to 5 mm, measured at the mandibular incisor edge. Therefore, clinicians should be careful and discuss this potential increased risk with the patients, when this movement is required by the treatment plan. Further clinical trials are needed to support the relevancy.

Abstract
PURPOSE OF REVIEW The aim of this article is to review the recent literature on orthognathic surgery for treatment of malocclusion and obstructive sleep apnea (OSA). The discussion outlines the refinements of the procedure and advances in technology. RECENT FINDINGS Maxillomandibular advancement (MMA) may be performed for complex malocclusion and OSA. Although orthodontic management followed by MMA has been the gold standard in managing complex cases, the surgery first approach for treatment of malocclusion has increased in popularity because of decreased treatment time and improved patient quality of life. MMA continues to be the gold-standard for treatment of refractory sleep apnea. Technological advancements, including 3D printing and virtual surgical planning, have enhanced the patient experience and provided more efficiency to this surgery. SUMMARY First introduced in the 19th century, orthognathic surgery has continuously been refined. Over the last few decades, there has been increasing support for a surgery first approach in the treatment of malocclusion. MMA has revolutionized the surgical treatment of OSA and provides the best opportunity for success or cure in patients with complex obstructive patterns. Technology has enhanced the surgical process and created more efficiency for the surgeon and patient. VIDEO ABSTRACT: http://links.lww.com/COOH/A40.

Abstract
INTRODUCTION Orthognathic surgery plays an important role in restoring aesthetic facial contour, correcting dental malocclusion, and the surgical treatment of obstructive sleep apnea. However, the rate of complications following bimaxillary as compared with single-jaw orthognathic surgery remains unclear. The authors therefore sought to evaluate complication rates following bimaxillary as compared with single-jaw orthognathic surgery MATERIALS AND METHODS:: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify comparison groups. Preoperative characteristics and postoperative outcomes were compared between groups. The listed procedures have different operating times and characteristics with longer time expected in the bimaxillary osteotomies group. Regression analyses were performed to control for potential confounders. RESULTS The 3 groups of interest included patients who underwent mandibular osteotomies (n = 126), LeFort I osteotomy (n = 194), and bimaxillary osteotomies (n = 190). These procedures have different operating times, with a longer time expected with bimaxillary osteotomies. Patients undergoing bimaxillary osteotomies had significantly higher rates of early wound complications, overall complications, longer mean operative time, and mean hospital length of stay. Performing bimaxillary osteotomies in the outpatient setting was an independent risk factor for wound complications (OR = 12.58; 95% CI: 1.66-95.20; P = 0.01), while an ASA class of 3 or more was an independent risk factor for overall complications (OR = 3.61; 95% CI: 1.02-12.75; P = 0.04) and longer hospital length of stay (β = 4.96; 95% CI: 2.64 - 7.29; P < 0.001). CONCLUSIONS Surgery in the outpatient setting as well as patient American Society of Anesthesiology physical status class 3 or higher were independent factors for postoperative adverse events in patients undergoing bimaxillary surgery. Our findings highlight the importance of addressing modifiable risk factors preoperatively and the need for closer postoperative monitoring in this patient population for optimal outcomes.

Abstract
CAD/CAM Revolution in Craniofacial Reconstruction Abstract. The face is an important part of the personality and at the same time fulfils a variety of tasks. Aesthetics and function form a unique unit. The formation of the field of oral and maxillofacial surgery began in the first decades of the last century. It includes the prevention, diagnosis, therapy and rehabilitation of diseases, injuries, malformations and changes of the complex structures of the face, oral cavity, jaw and teeth. In the meantime, oral and maxillofacial surgery has arrived in the 21st century. Today's oral and maxillofacial surgery is a link between medicine and dentistry and a protagonist in the implementation of digital workflows in clinical care. Individual solutions with patient-specific implants are the rule, computer-assisted techniques support the surgeon in the planning and performing of surgical procedures. This article intends to give you an insight into how our patients benefit from advanced technologies.
