Project description:BackgroundThe pandemic has challenged educational institutions to catalyze digitalization and rapidly develop online teaching formats. The aim of the study was to evaluate the teaching offered for oral and maxillofacial surgery at our university during the pandemic and to investigate the students' perceptions of the current situation.MethodsA 38-item questionnaire with five sections (demographic information, lectures, internships, e-learning, and pandemic-related solutions/effects) was created online. Most questions were answered on a 10-point Likert scale, with 1 indicating "fully agree/positive" and 10 indicating "totally disagree/negative." The remaining questions were either answered with yes/no, percent value, or open-ended text responses. All 3rd-5th year dental students were invited to voluntarily participate and were sent a link by email in a general mail shot.ResultsA total of 63.7% of the participants had no prior experience with online courses before the pandemic. The students stated that the change from face-to-face to online teaching worked very well in the last two semesters (mean = 2.73, standard deviation = 2.05). Overall, the pandemic had a rather positive influence on the acquisition of theoretical skills and a negative influence on the acquisition of practical skills (p < 0.0001). The evaluation showed that, compared to other dental clinics at our university, the department for oral and maxillofacial surgery was well prepared for the pandemic.ConclusionDigitalization of oral and maxillofacial surgery teaching in dental education is possible but depends on the institution's preparatory work and technological possibilities. The students declared a high acceptance of digital learning formats and indicated an increased motivation to learn due to e-learning. The pandemic's influence on the students' education was rated ambivalent.

Project description:PurposeThe 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 methodsOMS 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.ResultsA 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.ConclusionsSweeping 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.

Project description:ObjectiveTo assess the effect of virtual reality training on an actual laparoscopic operation.DesignProspective randomised controlled and blinded trial.SettingSeven gynaecological departments in the Zeeland region of Denmark.Participants24 first and second year registrars specialising in gynaecology and obstetrics.InterventionsProficiency based virtual reality simulator training in laparoscopic salpingectomy and standard clinical education (controls).Main outcome measureThe main outcome measure was technical performance assessed by two independent observers blinded to trainee and training status using a previously validated general and task specific rating scale. The secondary outcome measure was operation time in minutes.ResultsThe simulator trained group (n=11) reached a median total score of 33 points (interquartile range 32-36 points), equivalent to the experience gained after 20-50 laparoscopic procedures, whereas the control group (n=10) reached a median total score of 23 (22-27) points, equivalent to the experience gained from fewer than five procedures (P<0.001). The median total operation time in the simulator trained group was 12 minutes (interquartile range 10-14 minutes) and in the control group was 24 (20-29) minutes (P<0.001). The observers' inter-rater agreement was 0.79.ConclusionSkills in laparoscopic surgery can be increased in a clinically relevant manner using proficiency based virtual reality simulator training. The performance level of novices was increased to that of intermediately experienced laparoscopists and operation time was halved. Simulator training should be considered before trainees carry out laparoscopic procedures.Trial registrationClinicalTrials.gov NCT00311792.

Project description:BackgroundThe COVID-19 pandemic challenges our ability to provide surgical education, as our ability to gather and train together has been restricted due to safety concerns. However, the importance of quality surgical education has remained. High-fidelity simulation platforms have been developed that merge virtual reality video streams to allow for remote instruction and collaboration. This study sought to validate the use of a merged virtual reality (MVR) platform for the instruction and assessment of the fundamentals of laparoscopic surgery (FLS) skills.MethodsThis was a prospective randomized controlled non-inferiority study. Thirty participants were randomized between three groups: The standard group received in-person instruction and expert feedback, the experimental group received identical training via the MVR platform, and the control group practiced on their own, but received no feedback. All participants were pre-tested for baseline performance at the beginning of the study. Change in performance was evaluated immediately after training and one month later for retention. Ordinary one-way analysis of variance was used to evaluate the effects of time, group, and time-on-group.ResultsThe pre-test confirmed baseline homogeneity between the groups. MVR was non-inferior to standard in-person training for total FLS times on either the post-test (p = 0.632) or the retention test (p = 0.829). Performance was also identical between MVR and standard training groups for each of the individual FLS tasks. Each group improved significantly in nearly all tasks after practice; however, the standard and MVR training groups both improved significantly more than controls for the ligating loop, extracorporeal suturing, intracorporeal suturing, and total FLS task training but did not reach statistical significance for peg transfer and pattern cut tasks.ConclusionThis randomized, controlled trial has demonstrated the use of an MVR platform as non-inferior to in-person instruction for the FLS program, forming the foundation for future work on remote instruction and collaboration.

Project description:BackgroundVirtual reality (VR) training is widely used for surgical training, supported by comprehensive, high-quality validation. Technological advances have enabled the development of procedural-based VR training. This study assesses the effectiveness of procedural VR compared to basic skills VR in minimally invasive surgery.Methods26 novice participants were randomised to either procedural VR (n = 13) or basic VR simulation (n = 13). Both cohorts completed a structured training programme. Simulator metric data were used to plot learning curves. All participants then performed parts of a robotic radical prostatectomy (RARP) on a fresh frozen cadaver. Performances were compared against a cohort of 9 control participants without any training experience. Performances were video recorded and assessed blindly using GEARS post hoc.ResultsLearning curve analysis demonstrated improvements in technical skill for both training modalities although procedural training was associated with greater training effects. Any VR training resulted in significantly higher GEARS scores than no training (GEARS score 11.3 ± 0.58 vs. 8.8 ± 2.9, p = 0.002). Procedural VR training was found to be more effective than both basic VR training and no training (GEARS 11.9 ± 2.9 vs. 10.7 ± 2.8 vs. 8.8 ± 1.4, respectively, p = 0.03).ConclusionsThis trial has shown that a structured programme of procedural VR simulation is effective for robotic training with technical skills successfully transferred to a clinical task in cadavers. Further work to evaluate the role of procedural-based VR for more advanced surgical skills training is required.

Project description:The aim was to understand dental students' experiences with oral and maxillofacial surgery (OMS) teaching, their confidence levels in performing routine dento-alveolar operations, and the relationship between the students' confidence level and the number of teeth extracted during the clinical practice.The survey questionnaire was distributed to 32 students at Aljouf University College of Dentistry, Saudi Arabia during their fourth and fifth year in 2015. Respondents were asked to rate 19 items, which represent a student's confidence in performing routine surgical interventions, using a four-point Likert scale (1=very little confidence, 4=very confident). A multivariate regression was computed between average confidence and the variables: weekly hours devoted to studying oral and maxillofacial surgery, college grade point average, and the total number of teeth extracted.The response rate was 100%. Students revealed the highest level of confidence in giving local anesthesia (96.9%), understanding extraction indications (93.8%), and performing simple extractions (90.6%). Less confidence was shown with handling difficult extractions (50.0%), extracting molars with separation (50.0%) or extracting third molars (56.3%). The average confidence in performing surgical procedures was 2.88 (SD=0.55), ranging from 1.79 to 3.89. A given student's confidence increased with an increase in the total number of teeth extracted (P=0.003).It reveals a significant impact of undergraduate clinical training on students' confidence in performing oral and maxillofacial surgery clinical procedures: The more clinical experience the students had, the more confidence they reported.

Project description:Post graduate learning and assessment is an important responsibility of an academic oral and maxillofacial surgeon. The current method of assessment for post graduate training include formative evaluation in the form of seminars, case presentations, log books and infrequently conducted end of year theory exams. End of the course theory and practical examination is a summative evaluation which awards the degree to the student based on grades obtained. Oral and maxillofacial surgery is mainly a skill based specialty and deliberate practice enhances skill. But the traditional system of assessment of post graduates emphasizes their performance on the summative exam which fails to evaluate the integral picture of the student throughout the course. Emphasis on competency and holistic growth of the post graduate student during training in recent years has lead to research and evaluation of assessment methods to quantify students' progress during training. Portfolio method of assessment has been proposed as a potentially functional method for post graduate evaluation. It is defined as a collection of papers and other forms of evidence that learning has taken place. It allows the collation and integration of evidence on competence and performance from different sources to gain a comprehensive picture of everyday practice. The benefits of portfolio assessment in health professions education are twofold: it's potential to assess performance and its potential to assess outcomes, such as attitudes and professionalism that are difficult to assess using traditional instruments. This paper is an endeavor for the development of portfolio method of assessment for post graduate student in oral and maxillofacial surgery.

Project description:Octacalcium phosphate and its collagen composite have been recognized as bone substitute materials possessing osteoconductivity and biodegradation properties. We evaluated the effectiveness of octacalcium phosphate and its collagen composite used for bone augmentation in major oral and maxillofacial surgeries in a clinical trial. Octacalcium phosphate and its collagen composite were used in cases of sinus floor elevation in 1- and 2-stage, socket preservation, cyst, and alveolar cleft procedures. A total of 60 patients were evaluated for effectiveness after the implantation of octacalcium phosphate and its collagen composite. Although sinus floor elevation in 1-stage, cyst, and alveolar cleft cases met the criteria for the judgment of success, sinus floor elevation in 2-stage and socket preservation groups did not meet the criteria in the initial evaluation. However, an additional evaluation for reconfirmation revealed the effectiveness of octacalcium phosphate and its collagen composite in those groups, and all evaluation results ultimately indicated the success of this clinical trial. Therefore, this clinical trial suggested that application of octacalcium phosphate and its collagen composite for oral and maxillofacial surgery was safe and effective and that octacalcium phosphate and its collagen composite could be a bone substitute candidate instead of autologous bone.

Project description:Airway management for patients with recent oral facial injuries is always a challenge for the anesthetist. We describe how the glidescope (GLS) and fiber-optic (FOB) can be effectively combined in three patients undergoing oral maxillofacial surgeries after sustaining multiple facial fractures from trauma to allow less traumatic intubation, an option to visualize on either monitor and faster intubating time (mean 1 min 14 s for our cases) compared to the use of either one alone. Although it allows for better visualization of the vocal cords, it requires 2 trained anaesthetists to perform and this would need to be considered when using this technique.

Project description:INTRODUCTION: Virtual reality (VR) simulators have been developed to train basic endoscopic surgical skills outside of the operating room. An important issue is how to create optimal conditions for integration of these types of simulators into the surgical training curriculum. The willingness of surgical residents to train these skills on a voluntary basis was surveyed. METHODS: Twenty-one surgical residents were given unrestricted access to a VR simulator for a period of four months. After this period, a competitive element was introduced to enhance individual training time spent on the simulator. The overall end-scores for individual residents were announced periodically to the full surgical department, and the winner was awarded a prize. RESULTS: In the first four months of study, only two of the 21 residents (10%) trained on the simulator, for a total time span of 163 minutes. After introducing the competitive element the number of trainees increased to seven residents (33%). The amount of training time spent on the simulator increased to 738 minutes. CONCLUSIONS: Free unlimited access to a VR simulator for training basic endoscopic skills, without any form of obligation or assessment, did not motivate surgical residents to use the simulator. Introducing a competitive element for enhancing training time had only a marginal effect. The acquisition of expensive devices to train basic psychomotor skills for endoscopic surgery is probably only effective when it is an integrated and mandatory part of the surgical curriculum.
