With the use of cone beam computed tomography, intraoral scanning and 3D stereophotogrammetry, a virtual 3D head model of a patient can be reconstructed with image fusion. In this way, the malposition, deficiency and other anomalies at the level of bone, dentition and soft tissue can be quantified objectively. The desired position of the dentition, occlusion and soft tissue in the facial profile can be virtually drawn in and used as a guideline for treatment planning. Based on the principle of backward planning, it is possible to determine what repositioning of the jaw is required, where there is a need for bone augmentation and how many dental implants are necessary to obtain the desired treatment outcome. From this perspective, 3D treatment planning has become a treatment standard for the 4 clinical pillars supporting oral and maxillofacial surgery, specifically orthognathic surgery, implantology, craniofacial surgery and head & neck oncology. 3D planning has influenced today's workflow, planning of complex surgery and contributed to useful further innovations and efficient healthcare.

Proceedings of the OMS COVID-19 Response Conference.

The coronavirus disease 2019 (COVID-19) pandemic has affected the world in unprecedented ways. It is clear that this pandemic, unlike any public health challenge in recent memory, has the potential to fundamentally alter the delivery of many healthcare services, including the practice of oral and maxillofacial surgery. In response to this global health crisis, the Oral and Maxillofacial Surgery (OMS) COVID-19 Response Conference was held virtually on April 9, 2020, organized by oral and maxillofacial surgeons (OMSs) and administrators from multiple institutions to provide a forum for OMSs to discuss how COVID-19 has affected the specialty. As evidence-based information on COVID-19 continues to emerge, the present report serves as a method to disseminate the current opinions and management strategies from a variety of experts in OMS.

Early Effects of COVID-19 on Oral and Maxillofacial Surgery Residency Training-Results From a National Survey.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has had an immense impact on the healthcare industry. Oral and maxillofacial surgery (OMS) clinical practice uniquely exposes providers to COVID-19. The purpose of the present study was to understand the effect of the COVID-19 pandemic on OMS residency training programs (OMSRTPs): 1) training and education; 2) availability and use of personal protective equipment (PPE); 3) experience with, and use of, screening and viral testing; 4) resident experience; and 5) program director (PD) experience and observations of the immediate and future effects on OMSRTPs. MATERIALS AND METHODS: OMS residents and PDs in OMSRTPs in the United States were invited to participate in the present cross-sectional study from April 1, 2020 to May 1, 2020. A 51-question survey was used to evaluate the effects of COVID-19 on OMSRTPs and to assess the 5 specific aims of the present study. RESULTS: A total of 160 residents and 13 PDs participated in the survey, representing 83% of US states or territories with OMSRTPs. Almost all residents (96.5%) reported modifications to their training program, and 14% had been reassigned to off-service clinical rotations (eg, medicine, intensive care unit). The use of an N95 respirator mask plus standard PPE precautions during aerosol-generating procedures varied by procedure location, with 36.8% reporting limited access to these respirators. Widespread screening practices were in use, with 83.6% using laboratory-based viral testing. Residents scheduled to graduate in 2022 were most concerned with the completion of the graduation requirements and with decreased operative experience. Most residents (94.2%) had moved to web-based didactics, and a plurality (47%) had found increased value in the didactics. CONCLUSIONS: Sweeping alterations to OMS clinical practice have occurred for those in OMSRTPs during the COVID-19 pandemic. Although the overall OMSRTP response has been favorable, residents' concerns regarding the ubiquitous availability of appropriate PPE, operative experience, and completion of graduation requirements requires further deliberation.

[Contribution of 3D technology for maxillofacial surgery]. / Apport de la technologie 3D en chirurgie maxillo-faciale.

In recent years, 3D design and printing technology has been successfully used in maxillofacial bone reconstruction procedures. We had the opportunity to observe its benefits in the manufacture of custom facial implants. The production is so precise that perfect anatomical congruence and biocompatibility are possible. Within the plastic and maxillofacial surgery department of the University Hospital of Liège, we had the opportunity to perform two operations requiring facial skeleton redefinition implants. The purpose of this article is to highlight the current possibilities of facial prostheses via new 3D techno¬logies, but also the advantages and possible complications of this type of surgery.

Depuis quelques années, la technologie dite «conception et impression 3D¼ s'utilise avec succès dans les interventions de reconstruction osseuse maxillo-faciale. Nous en avons apprécié les bénéfices dans la confection d'implants faciaux sur mesure. La finesse de leur réalisation permet d'obtenir une parfaite congruence anatomique avec la meilleure biocompatibilité. Au sein du service de Chirurgie plastique et maxillo-faciale du CHU de Liège, nous avons effectué deux interventions avec implants 3D redéfinissant le squelette facial. Le but de cet article est de mettre en évidence les possibilités actuelles des implants faciaux via les nouvelles technologies 3D, mais également les avantages et les complications éventuelles de ce type de chirurgie.

The Past, Present, and Future of Dentoalveolar Surgery in China.

Dentoalveolar surgery, formerly known as dental surgery or oral surgery, is one of the basic branches of oral and maxillofacial surgery. While it has a long history; however, there are great differences in its evolution globally. This article presents a brief review on the development of dentoalveolar surgery internationally. Furthermore, a systematic review on its development in China, is detailed in 6 stages. However, while its development in China since 2005 has been most profound, improvements are still needed in treatment concepts, instruments, treatment processes, attention to high-risk populations and cooperation with other dental/medical disciplines. Future projections based on present standards of care are also presented.

The regenerative medicine in oral and maxillofacial surgery: the most important innovations in the clinical application of mesenchymal stem cells.

Regenerative medicine is an emerging field of biotechnology that combines various aspects of medicine, cell and molecular biology, materials science and bioengineering in order to regenerate, repair or replace tissues. The oral surgery and maxillofacial surgery have a role in the treatment of traumatic or degenerative diseases that lead to a tissue loss: frequently, to rehabilitate these minuses, you should use techniques that have been improved over time. Since 1990, we started with the use of growth factors and platelet concentrates in oral and maxillofacial surgery; in the following period we start to use biomaterials, as well as several type of scaffolds and autologous tissues. The frontier of regenerative medicine nowadays is represented by the mesenchymal stem cells (MSCs): overcoming the ethical problems thanks to the use of mesenchymal stem cells from adult patient, and with the increasingly sophisticated technology to support their manipulation, MSCs are undoubtedly the future of medicine regenerative and they are showing perspectives unimaginable just a few years ago. Most recent studies are aimed to tissues regeneration using MSCs taken from sites that are even more accessible and rich in stem cells: the oral cavity turned out to be an important source of MSCs with the advantage to be easily accessible to the surgeon, thus avoiding to increase the morbidity of the patient. The future is the regeneration of whole organs or biological systems consisting of many different tissues, starting from an initial stem cell line, perhaps using innovative scaffolds together with the nano-engineering of biological tissues.

The American Society of Maxillofacial Surgery Preceptorship Program: A Product of the 2013 American Society of Maxillofacial Surgery Executive Board Strategy Session and Survey.

One of the main goals of the American Society of Maxillofacial Surgery (ASMS) is to develop educational programs that increase expertise in maxillofacial surgery. We describe the outline of the new ASMS Preceptorship Program, a collective effort by ASMS members to increase access to all areas of maxillofacial surgery. Furthermore, we discuss the original survey pertinent to the development of this program, the results of the survey, and specifics regarding the structure of the program. We hope for the preceptorship program to be an excellent resource for members to mentor one another, develop intellectual and academic curiosity, provide avenues for collaboration, and further the ASMS's role in shaping maxillofacial surgery into the future.

Priorities for the education of members of the American Society of Maxillofacial Surgery.

We present the complete results of our 2013 survey of the members of the American Society of Maxillofacial Surgery (ASMS). We surveyed all 799 members of the Society from around the world regarding educational themes and modalities they wish to add to future ASMS educational programs. We also asked our members about surgical modalities and care paths in which they have the most expertise. The objective of the survey was to provide data that can be used to improve the education and training of the ASMS members. The results suggest that some widely taught topics perhaps should be taught less, whereas coverage of other topics should be increased.

Maxillofacial Surgery in Ukraine During a War: Challenges and Perspectives-A National Survey.

INTRODUCTION: The invasion of Ukraine by Russian troops on February 24, 2022, and the beginning of the full-scale war had huge humanitarian consequences. The major challenges facing the Ukrainian health care system included the disruption of medical infrastructure and logistics, the termination of the supply of expendable materials, significant migration, and a dramatic increase in high-velocity blast and gunshot injuries among combatants and civilians.The aim of the present study was to analyze the challenges and solutions in patient care faced by the Ukrainian system of maxillofacial surgery during the war in different regions of the country. MATERIALS AND METHODS: A cross-sectional study was designed and implemented as an online survey to collect national data concerning maxillofacial surgeons' experiences and professional activities. The study was initiated and supported by Bogomolets National Medical University (Kyiv, Ukraine), the Ukrainian representative of AO CMF (Arbeitsgemeinschaft für Osteosynthesefragen Craniomaxillofacial Surgery) and the University of Helsinki (Finland).The questionnaire was developed by specialists in maxillofacial surgery and sociologists and contained 65 close-ended questions. Surgeons who had not worked in this specialty in inpatient departments of hospitals since at least the beginning of the full-scale war were excluded from the study. We received and analyzed 97 responses that met the abovementioned criteria. The geography of respondents covered all the regions and the main cities of Ukraine, expect for the occupied territories. RESULTS: After a year of warfare, the percentage of surgeons who treated patients with blast and gunshot injuries increased from 43.4% to 86.6%. This percentage was higher in military hospitals and in regions located in the vicinity of the front line. We found that, during the war, 78.6% of respondents performed osteosynthesis in cases of high-velocity multifragmented facial bone fractures (in such cases, 58.3% of them strictly followed AO CMF recommendations, while 41.7% performed the fixation based on available hardware, existing technical possibilities and their own preferences). We found that 70.2% of respondents had the opportunity to apply Computer-Aided Design/Computer-Aided Manufacture technology and patient-specific implants for the treatment of gunshot injuries, 38.1% reported that their hospitals were able to perform microsurgical reconstructions for facial defects, 79.4% of respondents reported that their departments received humanitarian aid and support from volunteer organizations (either Ukrainian or international), which significantly facilitated the treatment process. CONCLUSIONS: According to this nationwide survey of Ukrainian maxillofacial surgeons during a year of the full-scale war, 86.6% of respondents were involved in the treatment of gunshot and ballistic injuries in civilians and combatants. The main problems reported by the respondents were (1) a lack of experience and knowledge related to the treatment of severe wounds, especially by secondary reconstruction, and (2) a deficit of resources (equipment, materials, and medications) under conditions of disrupted logistics and changes in the numbers and nosological distribution of patients. There were the opportunity to transfer the patients to European clinics (29.9%), online consultations (45.4%), collaboration with foreign surgeons who come to Ukraine asvolunteers (32%).

Knowledge mapping and research trends of distraction osteogenesis in oral and maxillofacial surgery.

BACKGROUND: Distraction osteogenesis (DO) has found extensive use in oral and maxillofacial surgery for correcting maxillofacial deformities due to its numerous advantages. However, comprehensive scientific and visual analyses of this field on a global scale are rare. Therefore, this study aims to provide a summary of the global trends and current status of DO in oral and maxillofacial surgery. METHOD: Publications concerning DO in oral and maxillofacial surgery were comprehensively searched and selected from the Web of Science Core Collection(WOSCC) database. We evaluated the annual contributions from institutions, journals, countries, and authors using bibliometric analysis software. RESULTS: A total of 541 publications were included in this study. The USA played a predominant role in this field, leading in both publication volume and international collaboration. Harvard University and the University of Hong Kong secured the top position in total publications, while the University of Texas System topped the list in total citations within this field. The Journal of Oral and Maxillofacial Surgery emerged as the primary contributing journal, and Cheung LX emerged as the primary contributing author in the field of distraction osteogenesis (DO) in oral and maxillofacial surgery. Keywords such as 'orthognathic surgery,' 'reconstruction,' and 'osteogenesis' are anticipated to be prominent topics in future research. CONCLUSION: Between 1995 and 2023, there has been rapid growth in the total number of publications within the field of distraction osteogenesis (DO) in oral and maxillofacial surgery. The USA stands out as the predominant country in this field. Surgeries, orthognathic surgery, and osteogenesis have emerged as prominent topics. The findings of our study offer valuable insights for scholars seeking to identify research hotspots and chart the developmental direction of DO in oral and maxillofacial surgery.

[Methods of tissue engineering of bone tissue in maxillofacial surgery].

For the last decade many experimental and clinical data about the study and application of regenerative medicine methods in the maxillofacial surgery were accumulated. For better bone regeneration mesenchymal stem cells are often used. Considering the general wariness of researchers in some aspects of cell therapy, methods of study of mesenchymal stem cells and the technologies of its clinical application are constantly being upgraded. This review will consider methods of tissue engineering used to regenerate bone tissue defects in maxillofacial surgery.

Trends and attitudes regarding head and neck oncologic surgery: a survey of United States oral and maxillofacial surgery programs.

PURPOSE: The purposes of this study were to: 1) estimate the prevalence and trends of American oral and maxillofacial surgery (OMS) programs in recruiting head and neck oncologic surgery (HNOS) -trained faculty, performing HNOS oncologic procedures and microvascular reconstruction, and presenting HNOS research at academic meetings; 2) estimate whether HNOS and microvascular reconstruction involvement varies among programs with or without a program director or chair trained in HNOS; 3) estimate whether HNOS involvement varies among those OMS programs that regularly attend and do not attend tumor board; 4) estimate whether HNOS involvement varies among those programs that have and have not presented HNOS research at an academic meeting; 5) estimate whether HNOS involvement varies among doctor of medicine-integrated and 4-year OMS programs. MATERIALS AND METHODS: Investigators developed and distributed a survey to all US OMS program directors and/or chair composed of questions regarding faculty prevalence and recruitment, frequency and trends in cases, and the priority of applicants for residency with regard to HNOS. There were 18 close-ended questions, and one open-ended question. Responses were recorded in categorical, Likert, ordinal, and numerical format. Bivariate associations were calculated using Fisher exact test and logistic regression. RESULTS: Sixty-three of 101 surveys were returned (62.3%). Ten program directors or chair completed a fellowship in HNOS (15.9%). Programs with an HNOS-trained program director or chair were more likely to have another HNOS-trained faculty member (P = .01), performed more malignant tumor resections (P < .001), neck dissections (P < .001), and microvascular free-flap reconstructions (P = .02) than programs without program directors or chair trained in HNOS. Programs that regularly attended tumor board performed an increasing number of malignant tumor resections (P = .008); and neck dissections (P = .003) than programs that did not regularly attend their institution's tumor board. Presentations of HNOS-related research at national meetings did not differ between doctor of medicine-integrated and 4-year OMS programs (P = .7). There was no difference in the prevalence of HNOS-trained program directors and chair between doctor of medicine-integrated and 4-year programs (P = .7). CONCLUSIONS: This study's data and comments suggest that programs involved in HNOS have a strong involvement in expanded scope OMS and related academic activities.

[Histological investigations in ambulatory oral surgery practice]. / Szövettani vizsgálatok az ambuláns szájsebészeti gyakorlatban.

In the practice of oral surgery correspondence with the pathologist is required in order to identify the lesions in question by histologic examination. By current legal regulations the histological evaluation of removed tissues is mandatory. In the presentation the authors process the data obtained in their Department since 2008. Coincidence of the clinical and histological diagnosis is analysed statistically such is the occurrence of various types of oral mucosa lesions and cysts. In cases of presumed malignancy the biopsies were carried out in a department with adequate oncological background. In indications of autoimmun deseases mainly in cases of Sjögren's syndrome the Department has been requested to carry out minor salivary gland biopsies. Statistical analysis of the findings of the minor salivary gland biopsies will also be discussed. The histological diagnoses have been provided by Prof. Zsuzsanna Suba MD, DMD, PhD of the Semmelweis University, Department of Oral and Maxillofacial Surgery, Oral Pathology Unit. In order of prevalence the most common histologically verified lesions were: radicular cyst, fibromas and granulation tissue. In 84.5% of the cases the histological findings confirmed the clinical diagnoses. In 44,5% of the cases Sjögren's syndrome was verified by the minor salivary gland biopsy. Although in most cases the histological examination supported the clinical diagnoses, close cooperation of the oral surgeon and pathologist is essential.

[A clinical study of dental surgery in anticoagulated patients]. / Antikoaguláns kezelésben részesülo betegek szájsebészeti ellátásának klinikai vizsgálata.

It is a worldwide trend that oral surgeons do not stop patients' anticoagulant therapy, but they leave the INR in the therapeutic range (INR: 2.0-3.0). The reason is that stopping drugs carries a higher risk of embolism, and thrombosis. The purpose of the present study is to reproduce these international guidelines in a Hungarian setting. On the day of surgery a lab test is performed immediately before the operation. These tests include coagulation data. A control (INR < 1.89) and an experimental group (INR: 2.0-3.0) were formed. Clinical complications, especially bleeding and thromboembolic complications were monitored. Based on the data and types of surgery no significant differences were found between the two groups. In conclusion it can be stated that it would be advisable to implement international guidelines and recommendations because there is a higher risk for anticoagulated patients if their therapy is stopped as if their INR is left in the therapeutic range. Of course appropriate wound care and bleeding control are necessary.
