Abstract
INTRODUCTION To assess the feasibility of a realistic model for learning oral flaps using 3D printing technology. MATERIALS AND METHODS A mould was designed to reproduce the mandibular gingival mucosa, and a mandibular model was created using a three-dimensional printer for training undergraduate students to perform gingival flaps. After a short interview about its use, the participants were asked to use the simulator and provide feedback using a 5-point Likert questionnaire. RESULTS The 3D-printed oral surgery flap training model was practical and inexpensive. The model was very realistic, educational and useful for hands-on training. CONCLUSIONS 3D printing technology offers new possibilities for training in dental treatments that are currently difficult to replicate. The use of this simulator for oral flap surgery was well-received and considered promising by the participants.

Abstract
PURPOSE The use of 3D-printing in every field of medicine is expanding, notably as an educational tool. The aim of this study was to assess how visuospatial abilities (VSA) of students may impact learning helped with 3D-printed models. METHODS Participants were undergraduate medical school students during their clinical rotation in oral and maxillofacial surgery in two French Universities. Students were included prospectively and consecutively from September 2021 to June 2023. First, a lecture about craniosynostosis was performed with the help of 3D-printed models of craniosynostotic skulls. Then, a mental rotation test (MRT) followed by a multiple-choice questions (MCQs) form about craniosynostosis presentations were submitted to the students. RESULTS Forty undergraduate students were finally included. Median MRT score was 15 (10.75;21) and median score to the MCQs was 13 (11.75;14). There was a significantly weak correlation between the MRT-A score and the score to the MCQs (rs = 0.364; p = 0.022). A simple linear regression was calculated to predict the result to the MCQs on MRT-A score [ (F(1,39) = 281.248; p < 0.0001), with a R2 of 0.878 ]. CONCLUSION This study showed that VSA has an impact on the recognition of complex clinical presentations, i.e. skulls with craniosynostosis. The correlation found between VSA and complex 3D shape recognition after learning aided with 3D-printed model is emphasizing the importance of VSA when using innovative technologies. Thus, VSA training should be envisioned during the curriculum.

Abstract
OBJECTIVES Aim of the present study was to create a pedagogical checklist for implant surgical protocol with an augmented reality (AR) guided freehand surgery to inexperienced surgeons using a head mounted display (HMD) with tracking. METHODS The anatomical model of a patient with two missing mandibular teeth requiring conventional single-tooth implants was selected. The computed tomography (CT) scans were extracted and imported into segmentation and implant planning software. A Patient-specific dental splint through an intermediate strut, supported 3D-printed QR code. A checklist was generated to guide surgical procedure. After tracking, the AR-HMD projects the virtual pre-surgical plan (inferior alveolar nerve (IAN), implant axis, implant location) onto the real 3D-printed anatomical models. The entire drilling sequence was based on the manufacturer's recommendations, on 3D-printed anatomical models. After the implant surgical procedure, CT of the 3D-printed models was performed to compare the actual and simulated implant placements. All procedures in the study were performed in accordance with the Declaration of Helsinki. RESULTS In total, two implants were placed in a 3D-printed anatomical model of a female patient who required implant rehabilitation for dental agenesis at the second mandibular premolar positions (#35 and #45). Superimposition of the actual and simulated implants showed high concordance between them. CONCLUSION AR in education offers crucial surgical information for novice surgeons in real time. However, the benefits provided by AR in clinical and educational implantology must be demonstrated in other studies involving a larger number of patients, surgeons and apprentices.

Abstract
Inferior alveolar nerve (IAN) lateralization (IANL) or transposition (IANT) are both techniques allowing for dental implant placement in posterior atrophic mandibles. The aim of this study was to systematically review the implant survival rate and the complications associated with IAN reposition techniques with simultaneous implant placement in atrophic posterior mandibles. This systematic review was conducted following PRISMA guidelines (Preferred Reporting Items for Systematic review and Meta-Analysis). The review was designed to answer the following PICO question: Is IAN repositioning (I) a safe and efficient technique (O) to treat patient looking for fixed dental rehabilitation of an atrophic posterior mandible (P). Thirty-three articles were reviewed, including a total of 899 patients, and approximately 950 IAN repositioning procedures. Dental implant survival rate ranged between 86.95% and 100% with a mean dental survival rate of 90.16%. Among the 269 patients who underwent IANT, there were 93% immediate neurosensory disturbance, and 15% persistent neurosensory disturbance. Among the 350 patients who underwent IANL, there were 93% immediate neurosensory disturbance, and 6% persistent neurosensory disturbance. IANT and IANL are reliable techniques allowing safe dental implant placement in atrophic posterior mandible with high patient satisfaction. IANL seems to cause less persistent neurosensory disturbances compared to IANT. The level of evidence is poor due to the high number of bias present in the included studies. IAN neurosensory disturbance assessment should be better homogenized in order to increase comparability.

Abstract
Craniofacial fibrous dysplasia (CFD) may be associated with major cosmetic or functional consequences. However, management recommendations for CFD are currently unavailable. Therefore, this systematic literature review aimed to review the existing approaches for CFD management and propose a management algorithm. The focus question was "What are the different options for CFD treatment and their complication rates?" The MEDLINE database was searched, and 33 articles evaluating a total of 1154 patients were reviewed. The bias assessment showed that 20 of the 33 studies had a high or intermediate risk of bias, mainly because of retrospective data collection and small patient numbers. Radical surgery showed a lower recurrence rate than debulking, but its use should be weighed against the morbidity caused by the reconstruction performed in this technique. Orbital decompression using a radical technique or debulking is effective in cases showing exophthalmos or dystopia. Surveillance is a viable option for asymptomatic and/or non-progressive lesions. In cases showing optic nerve compression, prophylactic decompression should be avoided, and decompression should be performed only when patients show diminished visual acuity or visual field defect. Although bisphosphonates have shown efficacy in pain management, their posology requires further discussion. A management algorithm is presented.

Abstract
Guided bone regeneration (GBR) is a validated technique with satisfactory outcomes during 30 years of follow-up. The use of polytetrafluoroethylene (PTFE) membrane for vertical augmentation has been studied extensively. However, studies have reported exposure rates of up to 31%, there is no consensus on the management of postoperative exposure. The objective of this study was to propose a management approach for postoperative exposure of polytetrafluoroethylene (PTFE) membranes in alveolar ridge reconstruction. MATERIAL AND METHOD An electronic search in PubMed Central's and additional electronic databases was performed. The search strategy was limited to human studies, full-text English or French articles published from 1990 until april 2023. The extracted data included defect location, membrane type, biomaterials, time to postoperative exposure, and Fontana classification stage. Protocol bias assessment was performed using an adaptation of the QUADAS-2 tool. This review has been registered on PROSPERO (ID: CRD42023445497). RESULTS A total of 43 articles were found to be eligible, and 11 of these met the predefined inclusion and exclusion criteria. Based on the results of this systematic review, an algorithm for the management of PTFE membrane exposure is proposed. CONCLUSION Postoperative membrane exposure is not a determining factor for the success of bone grafting. In cases with postoperative complications, the majority of cases still achieved adequate implant-prosthetic rehabilitation. Lastly, this series of 11 articles was insufficient to draw conclusions regarding good practice recommendations. A larger series is required to validate the specific management approaches.

Abstract
The aim of this study was to assess the feasibility of complex unicortical calvarial harvesting by using the Cold Ablation Robot-Guided Laser Osteotome (CARLO® primo+). A cadaveric study was performed with a progressive complexity of the bone harvesting. This preliminary study on the cadaveric cranial vault area examined the tracking precision, the strategies, settings and durations of harvesting, the accuracy of the unicortical bone cutting, and the risk of dura exposition. All sampling was realised with no more difficulty than that experienced during the standard procedure. No bicortical cutting occurred during CARLO® primo + robot-guided laser cutting. During the second sampling, dura was partially exposed due to improper angulation of the curved osteotome during harvesting. Complex unicortical calvarial harvesting using robot-guided laser appears to be feasible and safe. In the future, robotic approaches will probably replace current surgical techniques using cutting guides and help reduce intraoperative inaccuracies due to the human factor.

Abstract
INTRODUCTION the aim of this study was to report and assess the management and implant rehabilitation of oligodontia patients since its recognition in 2012 by french authorities in the nomenclature. MATERIAL AND METHODS we conducted a retrospective study in the Maxillofacial Surgery and Stomatology Department of the Lille University Hospital between January 2012 and May 2022. Patients had to present an oligodontia recognized under the ALD31 in adulthood, and to have benefited from a pre-implant/implant surgical treatment in the unit. RESULTS a total of 106 patients were included in the study. The mean number of agenesis was 12 per patient. The most missing teeth are the ones at the end of the series. After a pre-implant surgery phase including orthognathic surgery and/or bone grafting, 97 patients benefited from implant placements. The mean age for this phase was 19.38. A total of 688 implants were placed. The median number of implants placed was 6 per patient and 5 patients presented implant failures after or during the osseointegration phase (16 implants lost). The implant success rate was 97.6%. 78 patients benefited from rehabilitations by fixed implant-supported prostheses and 3 by implant-supported mandibular removable prostheses. DISCUSSION The described care pathway seems to us adapted to the patients followed in our department, with good functional and esthetic results. It would be necessary to evaluate on a national scale to adapt the management process.

This retrospective study included patients who presented with head and neck SFTs. Clinical, radiological, and histological information and data regarding the treatments performed were collected. The risk of locoregional and distant metastases was calculated, and for orbital SFTs a specific classification was used. Overall, 34 patients were included. The majority of the SFTs were found in the oral cavity (n = 10), followed by the neck region (n = 8). The mean time to recurrence was 67.4 months. All patients underwent primary surgical resection. Recurrence was observed in five patients with a low risk of locoregional recurrence and distant metastasis. The treatment of choice is complete resection. Recurrence seems to be highly correlated with positive surgical margins. The safety margin should be increased when removing the lesion, and long-term follow-up should be performed.

Abstract
The current standard approach to treat class II malocclusion is orthodontic preparation followed by a mandibular advancement through bilateral sagittal split osteotomy associated or not with a genioplasty. However, when a malocclusion with an important incisors' axis deviation is associated with a chin malposition, an alternative technique can be considered: simultaneous mandibular anterior segmental osteotomy and genioplasty. This technique is performed without a bony bridge between osteotomies. Care must be taken not to wound the lingual mucosa. If preserved, this technique is safe. The result is stable and predictable.

Abstract
INTRODUCTION The objective of this study was to compare the length ratios obtained on panoramic radiography and computed tomography (CT) to verify whether the former is adequate for diagnosing coronoid process hyperplasia. METHODS A case series of patients with coronoid process hyperplasia was investigated. Length ratios between the coronoid process and condyle were measured on panoramic radiographs by using the Levandoski method and on CT scans by using the methods described by Tavassol et al. and Stopa et al. The mean length ratios obtained using the three measurement methods were compared. RESULTS The mean length ratio measured with the Levandoski method was significantly lower than that measured with the method described by Stopa et al. (1.09 [0.09] vs. 1.21 [0.09]; P = 0.0001) and lower than that measured with the method described by Tavassol et al. (1.09 [0.09] vs. 1.34 [0.44]; P = 0.013). CONCLUSION Panoramic measurement of the coronoid process by using the Levandoski method tended to underestimate the length ratio, emphasizing the importance of using a scanographic measurement method at the slightest doubt to confirm the diagnosis of coronoid process hyperplasia.

Abstract
Temporomandibular disorders (TMD) are complex pathologies responsible for chronic orofacial pain. Intramuscular injection of botulinum toxin A (BoNT/A) has shown effectiveness in knee and shoulder osteoarthritis, as well as in some TMDs such as masticatory myofascial pain, but its use remains controversial. This study aimed to evaluate the effect of intra-articular BoNT/A injection in an animal model of temporomandibular joint osteoarthritis. A rat model of temporomandibular osteoarthritis was used to compare the effects of intra-articular injection of BoNT/A, placebo (saline), and hyaluronic acid (HA). Efficacy was compared by pain assessment (head withdrawal test), histological analysis, and imaging performed in each group at different time points until day 30. Compared with the rats receiving placebo, those receiving intra-articular BoNT/A and HA had a significant decrease in pain at day 14. The analgesic effect of BoNT/A was evident as early as day 7, and lasted until day 21. Histological and radiographic analyses showed decrease in joint inflammation in the BoNT/A and HA groups. The osteoarthritis histological score at day 30 was significantly lower in the BoNT/A group than in the other two groups (p = 0.016). Intra-articular injection of BoNT/A appeared to reduce pain and inflammation in experimentally induced temporomandibular osteoarthritis in rats.

Abstract
Oligodontia is a developmental dental anomaly defined by the absence of 6 or more permanent teeth, excluding the third molars. We performed a review with a systematic approach and proposed a guideline for the choice of the bone augmentation surgery. The different bone augmentation technique terms were searched in the PubMed and Science Direct database. Clinical studies were eligible if they reported on pre-implant surgery in patients with oligodontia. The database search yielded 400 studies after duplicates removed. Thirty studies were finally included, involving 410 patients. Sixty-three sinus lifts were performed in 37 patients with no failure. Thirteen out of 33 patients with iliac bone transplantation and two out of 24 with parietal bone transplantation had resorption, one out of 4 patients who received allogeneic bone block had complete failure. Seventy-eight patients underwent guided bone regeneration, none had bone loss. No failure was found with the alveolar distraction osteogenesis technique. Four out of thirteen patients developed permanent hypoesthesia after inferior alveolar nerve transposition. The cumulative implant survival rate was 94.4% after bone augmentation procedures. Extensive edentulous areas should be grafted with parietal bone, as iliac grafts present a greater risk of resorption. Smaller edentulous areas should be treated by endobuccal harvesting or guided bone regeneration. Osteogenesis distraction and nerve transposition are effective surgeries for medium-to-large mandibular edentulous spaces. The implant survival rate is not significantly different between implants placed in grafted and nongrafted bone, the appropriate choice of bone augmentation technique can reduce the risk of peri‑implant bone resorption.

Abstract
BACKGROUND The objective of this study was to evaluate the mouth opening (MO) in patients with Langenbeck or Jacob diseases after a multimodal treatment combining the coronoidectomy and a self or assisted postoperative rehabilitation. METHODS This observational retrospective study included patients who had clinically impacted MO limitation. All patients underwent unilateral or bilateral coronoidectomy and then physical therapy for at least 3 months. MO measurements were compared between the preoperative time (M0), the immediate postoperative time (M1) and the last follow-up (M2). Other data regarding the surgical procedure and the postoperative rehabilitation were collected. RESULTS Twenty patients were included. The MO was significantly improved from 19.15 ± 7.02 mm at M0 to 38.00 ± 7.62 mm at M1 (p = 0.0002). After a mean follow-up of 21.5 ± 40.5 months, the mean MO was 32.85 ± 5.69 mm (M2). All patients underwent coronoidectomy through an intraoral approach except for one patient who was given a combined extra-oral approach for a recurrent disease. Rehabilitation protocol included assisted physiotherapy and self-rehabilitation in 7 patients as well as just self-rehabilitation in 13 patients. No patient showed worsening or stagnation of MO. CONCLUSIONS The multimodal treatment combining the surgical removal of the coronoid process and an active rehabilitation performed by the patient himself or assisted by a physiotherapist seems effective in Langenbeck or Jacob diseases.

Abstract
OBJECTIVES Main aim of the study was to explore the association between genetic polymorphisms in ACTN3 and bruxism. Secondary objectives included masseter muscle phenotypes assessment between bruxers and non-bruxers and according to genetic polymorphisms in ACTN3. MATERIALS AND METHODS Fifty-four patients undergoing orthognathic surgery for correction of their malocclusion were enrolled. Self-reported bruxism and temporomandibular disorders status were preoperatively recorded. Saliva samples were used for ACTN3 genotyping. Masseter muscle samples were collected bilaterally at the time of orthognathic surgery to explore the muscle fiber characteristics. RESULTS There were significant differences in genotypes for rs1815739 (R577X nonsense) (p = 0.001), rs1671064 (Q523R missense) (p = 0.005), and rs678397 (intronic variant) (p = 0.001) between bruxers and non-bruxers. Patients with self-reported bruxism presented a larger mean fiber area for types IIA (p = 0.035). The mean fiber areas in individuals with the wild-type CC genotype for rs1815739 (R577X) were significantly larger for type IIA fibers (1394.33 μm2 [572.77 μm2 ]) than in those with the TC and TT genotypes (832.61 μm2 [602.43 μm2 ] and 526.58 μm2 [432.21 μm2 ] [p = 0.014]). Similar results for Q523R missense and intronic variants. CONCLUSIONS ACTN3 genotypes influence self-reported bruxism in patients with dentofacial deformity through specific masseter muscle fiber characteristics.

Abstract
OBJECTIVE To compare two agents that can induce a rat model of temporomandibular joint osteoarthritis (TMJOA) by chemical induction: monosodium iodoacetate (MIA) and collagenase type 2 (Col-2). We wished to ascertain the best agent for assessing drug-delivery systems (DDSs). METHOD Male Wistar rats underwent intra-articular injection with MIA or Col-2. They were manipulated for 30 days. The head withdrawal threshold (HWT), immunohistological assessment, and positron emission tomography (PET) were used to evaluate the relevance of our models. RESULTS For both the MIA and Col-2 groups, pain persisted for 30 days after injection. Change in the HWT showed that Col-2 elicited a strong action initially that decreased progressively. MIA had a constant action upon pain behavior. Histology of TMJ tissue from both groups showed progressive degradation of TMJ components. CONCLUSIONS MIA and Col-2 induced orofacial pain by their local chemical action on TMJs. However, based on a prolonged and greater sustained effect on the pain threshold, persistent histological changes, and imaging results, MIA appeared to be more suitable for creation of a rat model of TMJOA for the study of DDSs.

Abstract
INTRODUCTION Although most localized odontogenic infections can be managed successfully without complications, some can cause extensive morbidity through the onset of cervicofacial cellulitis. The management of these more severe infections generally requires emergency treatment, including surgical treatment under general anesthesia, and prolonged length of hospital stay. MATERIAL & METHODS In this work, we assessed the impact of the provision of a hospital-based dental emergency department on the regional incidence of severe odontogenic cellulitis in a socioeconomically precarious region. Monthly case rates of odontogenic cellulitis treated between January 2010 and December 2019 at the hospital-based dental emergency department of Lille Medical University Hospital were collected. RESULTS The mean number of monthly severe odontogenic cellulitis cases treated under general anesthesia was significantly higher before than after the inception of the hospital-based dental emergency service [14.07 (5.83) vs 8.79 (4.42); p<0.0001]. Conversely, the monthly mean number of collected odontogenic cellulitis cases treated under local anesthesia was significantly lower before the emergency service was set up [22.42 (12.73) vs 43.32 (23.41); p<0.0001]. CONCLUSION The provision of a hospital-based dental emergency department resulted in a decrease in severe dental infections in a region with high indices of socioeconomic precarity, morbidity and mortality. Greater accessibility to dental care allows for the rationalization of care through more precocious and fewer burdensome procedures.

Abstract
INTRODUCTION Autogenous bone grafting (ABG)-combined or not with Le Fort I osteotomy (LFIO)-and zygomatic implants (ZI) are two reliable techniques for the fixed rehabilitation of atrophic maxillae. ZI allow a reduced treatment duration with no need to graft, immediate loading and in principle less morbidity. The aim of this retrospective study was to compare these two protocols on oral health-related quality of life (OHRQoL). We also discussed implant and prosthetic survival rates, and biological complications. MATERIAL AND METHODS All patients who benefited from ZI or ABG with conventional implants (CI) for a fixed maxillary rehabilitation, from November 2011 to April 2019, were included: 21 patients in the ABG group and 22 in the ZI group. OHRQoL was evaluated postoperatively by OHIP-14 questionnaire. RESULTS OHIP-14 median scores were respectively 6.5 (interquartile range [IQR] 2.0-13.0) and 6.0 (IQR 3.0-10.0) without significant difference (p = 0.97). Implant/prosthetic survival rates were 97.9%/100% and 97.1%/95.5%. Biological complications rates were 33.3% and 36.4% without significant difference (p = 0.83). DISCUSSION The type of surgery or prosthesis does not seem to affect final OHRQoL, implant and prosthetic survival rates or biological complications rates.

Abstract
PURPOSE Cervical cellulitis is an infrequent but serious infection. The management of the upper airways is difficult, at the actual time of intubation but also regarding the necessity of maintaining mechanical ventilation. The objective of this study is to identify risk factors on admission to the intensive care unit for difficult ventilatory weaning in patients with cervical cellulitis. METHODS Between January 2013 and December 2018, this retrospective observational study was performed in an intensive care unit with 10 beds in a university hospital recognized as a reference center for the management of cellulitis. All intensive care patients receiving mechanical ventilation after surgery for cervical cellulitis were eligible. Difficult ventilatory weaning was defined as mechanical ventilation lasting more than 7 days or failure of extubation as established by the WIND 2017 study. RESULTS We included 120 patients with severe cervical cellulitis. The median age was 43 years. Eighteen patients (16%) presented mediastinal extension. The risk factor for difficult ventilatory weaning (n = 49) in multivariate analysis was a high level of procalcitonin on admission (OR at 1.14[1.005-1.29]; p<0.042) and the protective factor was surgery in an expert center (OR at 0.11[0.026-0.47]; p<0.003). Eight patients required a tracheotomy in our study: 3 patients during surgery and at a later time for the other 5 of our 8 patients. CONCLUSION No intensive care studies have investigated ventilatory weaning risk factors in patients with cervical cellulitis. Yet simple criteria seem to predict this risk. It is now necessary to confirm them by a multicenter prospective study.

Abstract
BACKGROUND Head and neck cancers (HNC) have poor survival prognosis, as tumors are often diagnosed at advanced stages in patients consulting late. The first lockdown linked to the 1st wave of COVID-19 (Coronavirus Disease 2019) disrupted consultation schedules in France. OBJECTIVE The principal aim of the present study was to analyze consultation wait time in HNC during and after lockdown, in our university expert oncology reference center, to disclose any increase in treatment wait time. METHODS A single-center retrospective study included patients with a first diagnosis of HNC. Three groups were distinguished: "lockdown", "post-lockdown", and a "control" group (corresponding to a reference period 1 year earlier). Intervals between first oncologic consultation and multidisciplinary tumor board (FC-MTB) and between MTB and first treatment (MTB-T) were assessed. RESULTS One hundred and seven patients were included in the control group, 60 in the lockdown group and 74 in the post-lockdown group. There was no increase in median FC-MTB interval (respectively 35, 29 and 28 days) between the lockdown and post-lockdown groups compared to the control group (respectively P=0.2298 and P=0.0153). Likewise, there was no increase in MTB-T interval (27, 20 and 26 days respectively) (P=0.4203). CONCLUSION No increase in wait times was observed during the lockdown and post-lockdown periods in our center.

Abstract
Oral mucosal melanoma (OMM) is the subject of few studies, resulting in a lack of understanding. The aim of this study is to review the current literature on OMM. The term searched was "oral mucosal melanoma" between 01/01/2000 and 03/15/2021 in the PubMed Database (MEDLINE). Patients presenting with OMM and treated in our center between January 2009 and January 2020 were included in a case series. Demographics, location, risk factors, genetic mutations, treatment performed, and overall survival (OS) rates were evaluated. The PubMed database search yielded a total of 513 results, thirty-eight articles were finally included, which amounted to 2230 cases of OMM. 13 patients were included in the case series. A male-to-female ratio of 1.28:1.00 was found with a mean age at first diagnosis of 58.2 years old. Hard palate (1060 cases) and then gingiva (794 cases) were the two main locations. No risk factors could be identified. OMM were staged III or IV at diagnosis. Mutations were described as such: KIT in 14.6% of cases, BRAF in 7%, and NRAS in 5.6%. Treatment protocols varied but radical surgery was the cornerstone treatment associated with adjuvant therapies. Immunotherapy has not been evaluated for OMM. OS rates were 43.4% at 3 years, 33.1% at 5 year and 15.4% at 10 years. OMM show distinct features from cutaneous melanoma (CM): typical locations, no identified risk factors, different mutations profile, worse prognosis with advanced stage at diagnosis. Targeted therapies are still underused compared to CM.

Abstract
INTRODUCTION Craniosynostosis is a rare and complex pathology, and visuospatial skills are necessary for a good understanding of the condition. While the use of three-dimensional (3D) models has improved the understanding of complex craniofacial anatomy, no study has evaluated the impact of this teaching support on long-term retention. MATERIALS AND METHODS Our randomized controlled trial was designed to compare the long-term retention of information with 3D-printed models of four types of craniosynostosis versus classic 3D reconstructions displayed in two-dimensional (2D) among undergraduate students. All students benefited from the same standardized course followed by the manipulation of the learning tool associated with the group for 15 minutes. Long-term retention was assessed by the capability to properly recognize different types of craniosynostosis 3 weeks after the course. RESULTS Eighty-five students were enrolled. Previous educational achievements and baseline visuospatial skills were similar between the groups. The bivariate analysis showed the mean score in the 3D and 2D groups were 11.32 (2.89) and 8.08 (2.81), respectively (p < 0.0001). CONCLUSIONS 3D-printed models of structures with spatial complexity such as various craniosynostosis patterns improve significantly medical students' long-term retention, indicating their educational efficacy.

Abstract
Introduction: Central giant cell granuloma (CGCG) of the jaws is not a common lesion. Only five cases are reported in the mandibular condyle. Observation: A 25 year-old male presented with preauricular swelling and a premature occlusal contact on the molars. The lesion had radiological features of aggressiveness and a high metabolic uptake. Initial biopsy was misleading. The lesion was treated surgically by resection. Discussion: Histologically, CGCG are very similar to other giant cell lesions such as GCT (Giant cell Tumor) or BTH (brown tumor of hyperparathyroidism). The standard treatment is surgical either by curettage or resection. Only 6 cases have been described in the literature, including this one. The diagnosis is difficult, relying on a bundle of clinical, radiological and histological arguments. However, radical surgery should be performed to avoid the tumor recurrence. The genetic mutations associated with CGCG (notably TRPV4 and RAS pathway) may explain why this tumor is mostly found in the dental part of the jaws and only rarely in the mandibular condyle.

Abstract
Temporomandibular joint (TMJ) synovial cysts are rare, unlike peripheric locations like the wrist or the knee. They share similar presentations with ganglion cyst, benign and sometimes malignant lesions. Only histopathological analysis confirms diagnosis in some cases, finding a true cyst lined by synoviocytes containing synovial fluid. They seem to be related to an increased articular pressure following trauma. In this study we present two cases of TMJ synovial cyst and a systematic review of the literature. A total of 32 cases were retrieved from published literature in PubMed, Cochrane Library and ClinicalTrials.gov databases using the search terms 'TMJ synovial cyst', 'temporomandibular synovial cyst', 'jaw joint synovial cyst'. Swelling (91.3%) and pain (78.3%) were the most common symptoms. MRI was the most commonly used imaging modality that was found to be beneficial for diagnosis. In almost all cases the cyst was removed under general anesthesia, allowing histopathological examination. Only two patients still had pain after removal of the cyst. No recurrence was observed .

Abstract
BACKGROUND For visually impaired or blind patients, the experience of pregnancy sets them apart from nondisabled people for whom viewing of the first ultrasound has become a social and emotional milestone. OBJECTIVE We proposed the use of 3D-printed models to allow the societal inclusion of visually impaired or blind expectant parents. PATIENT INVOLVEMENT Visually impaired expectant parents were proposed to touch a 3D printed sensory vector of their prenatal classic ultrasonography. METHODS After a classic ultrasound assessment was performed, selected volumes were processed and 3D-printed with acrylonitrile butadiene styrene. Patient satisfaction was recorded after they manipulated the models. RESULTS A total of 42 prenatal 3D prints were for 12 expectant parents, used during 20 ultrasonographic sessions with visually impaired or blind expectant parents. During 13 of them (65%), it was the mother who was affected by a visual loss whereas the father was the parent affected by the disability during 7 sessions (35%). The parent affected by the disability was congenitally blind and Braille-reader in 9 ultrasonography sessions (45%). All expectant visually impaired or blind parents expressed very significant satisfaction with the use of 3D models for inclusive use. DISCUSSION We have shown that acrylonitrile butadiene styrene-printed models improve the sonographic experience of visually impaired or blind expectant parents. They can thereby perform their own mental representation process by extrapolating sensory information obtained from the 3D tactile support. PRACTICAL VALUE These low-cost 3D-printed models improve the inclusion of visually impaired or blind expectant parents, by offering them a sensory vector of information.

Abstract
3D-printing is part of the daily practice of maxillo-facial surgeons, stomatologists and oral surgeons. To date, no French health center is producing in-house medical devices according to the new European standards. Based on all the evidence-based data available, a group of experts from the French Society of Stomatology, Maxillo-Facial Surgery and Oral Surgery (Société Française de Chirurgie Maxillofaciale, Stomatologie et Chirurgie Orale, SFSCMFCO), provide good practice guidelines for in-house 3D-printing in maxillo-facial surgery, stomatology, and oral surgery. Briefly, technical considerations related to printers and CAD software, which were the main challenges in the last ten years, are now nearly trivial questions. The central current issues when planning the implementation of an in-house 3D-printing platform are economic and regulatory. Successful in-house 3D platforms rely on close collaborations between health professionals and engineers, backed by regulatory and logistic specialists. Several large-scale academic projects across France will soon provide definitive answers to governance and economical questions related to the use of in-house 3D printing.

Abstract
OBJECTIVE The purpose of this study was to assess whether common biological factors are correlated with a longer hospital stay. STUDY DESIGN All patients having odontogenic cellulitis, treated from January 2019 to December 2019 at Lille University Hospital, and requiring surgical drainage under general anesthesia, were included, retrospectively. Data, such as length of hospital stay and biological factors, namely, C-reactive protein (CRP) level, Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score, and bacterial samples were collected. RESULTS Significant moderate-strong correlations were found between postoperative length of stay and patients' LRINEC score (rs = 0.556) and presurgical CRP level (rs = 0.579). There was a significant moderate correlation between postoperative length of stay and presurgical procalcitonin level (rs = 0.451), and a weak correlation between postoperative length of stay and presurgical white blood cell count (rs = 0.282). Linear regression verified CRP as an independent predictor of length of hospital stay, showing a significant linear relationship between them (p < 0.0001). A significant regression equation was found (F(1,65) = 27.089; p = 0.0001), with an R2 of 0.294. CONCLUSION In this study, CRP was the key biological predictor of length of hospital stay. STATEMENT OF CLINICAL RELEVANCE The ability to predict length of hospital stay and identify patients requiring intensive care management, using simple and inexpensive biological parameters (such as CRP), will enable more cost-effective care and efficient hospital bed management.

Abstract
INTRODUCTION Mandibular angle fractures are very common and are associated with the highest risk of complications. The aim of this study is to evaluate the correlation between impacted lower third molar and mandibular angle fracture complications. MATERIAL AND METHODS All patients presenting with a mandibular angle fracture and at least 2 months follow up were retrospectively included. The following complications were recorded: post-traumatic malocclusion, mouth opening limitation, inferior alveolar nerve hypoesthesia, infection, delayed union, hardware loosening. The patients were divided in two groups: impacted lower third molar or erupted/absent lower third molar. RESULTS A total of 68 patients were included, lower third molar was impacted in 36 cases and erupted/absent in 32 cases. 40 complications were recorded in 27 patients at 2 months. No statistically significant difference could be found about malocclusion, mouth opening limitation and inferior alveolar nerve hypoesthesia. A lower rate of persistent inferior alveolar nerve hypoesthesia (p = 0.0557) in patients with impacted lower third molar (19.4%) was observed compared to patients without impacted lower third molar (40.6%). There was no occurrence of delayed union and hardware loosening in impacted lower third molar group, whereas 5 delayed unions and 4 hardware loosening were recorded in erupted/absent lower third molar group. Finally, the rate of patients with at least one of the 6 complications is significantly higher in the erupted/absent lower third molar group (17/32, 53.1%) than in the impacted lower third molar group (10/36, 27.8%), p = 0.033. DISCUSSION The risk of overall complication is decreased when lower third molar is impacted in mandibular angle fracture. This supports the idea of a role of the impacted lower third molar in fracture reduction and stability.

Abstract
PURPOSE Nonsurgical treatment of mandibular fractures secondary to medication-related osteonecrosis of the jaw (MRONJ) or osteoradionecrosis (ORN) mostly results in nonunion, whereas nonsurgical fracture treatment of atrophic fractures can achieve favorable results in selected cases. The aim of this study was to compare callus formation in pathological mandibular fractures due to MRONJ, ORN, or extreme mandibular atrophy. METHODS A retrospective cohort study reviewing the medical records of all MRONJ-, ORN-, or atrophy-related fractures treated at the departments of maxillofacial surgery in the Leuven or Lille university hospitals between 2010 and 2019 was undertaken. The primary predictor variable in this study was disease state (MRONJ, ORN, or extreme mandibular atrophy). The primary outcome variable was callus formation after 1 month of follow-up (present, absent). Additional study variables measured included patient age and gender. T-tests, Fisher exact tests, and multiple logistic regression were used for statistical analysis. The significance level was set at P < .05. RESULTS Seventy patients were analyzed (12 MRONJ cases, 54 ORN fractures, 4 atrophic fractures). The callus formation prevalence in nonsurgically approached fractures secondary to ORN and MRONJ after 1 month of follow-up was 3.03% (2/66 cases). In contrast, callus was detected in all patients in the mandibular atrophy-related fracture group. Osteonecrosis was statistically correlated with impaired callus formation (P = .0121). CONCLUSION Whereas one would expect indirect fracture healing and thus callus formation to occur in all non-surgically treated fractures, our data demonstrate its absence in the majority of MRONJ- and ORN-related fractures. Multiple plausible explanations for this phenomenon were identified: periosteal damage with loss of callus-forming cells, compromised vasculature, and bacterial colonization.

Abstract
INTRODUCTION Maxillofacial reconstruction with bony free flap is a classical technique. However, pedicle ossification after such reconstruction is a misunderstood complication that is rarely reported in the literature. It is usually manifested as trismus, neck pain, and hard swelling, but it is predominantly asymptomatic and, thus, mainly incidentally discovered at a later stage. The aim of our study is to propose a classification for pedicle ossification based on both radiological features and vascular calcification progression. We also describe a case of metachronous ossification after two fibula free flap procedures. MATERIAL & METHODS Our observational study includes all patients from our unit who underwent maxillofacial reconstruction with bony free flap from 2003 to 2018. We collected all cases of pedicle ossifications identified during the follow-up and described the radiological status of each one to categorise them in different groups and propose a classification scheme for the same. RESULTS Radiological and histological analysis showed a progressive three-step evolution of pedicle ossification, starting from the media, progressing into the lumen, and then reaching completion in the extravascular region. The final stage was observed in all symptomatic patients. CONCLUSION Pedicle ossification is a progressive process that passes through three successive histological stages that may be associated with factors such as smooth muscle cell phenotype modification [1]. This complication may lead to more severe clinical symptoms and may require surgery for removal of the calcification.

Abstract
INTRODUCTION The aim of this study is to assess a pioneering technique for atrophic premaxilla restoration. The objective is to reposition an implant reconstruction zone into a position both anatomically and physiologically suitable for occlusal function. Indeed, unlike the other few articles published on the correctional osteotomy of the implant in an inadequate situation, we have planned here an initially «unsuitable» insertion in order to benefit of the available bone mass. MATERIAL AND METHOD 3 patients aged 14-20 years old (1 woman and 2 men) were operated on at the maxillo-facial department of Lille 2 University Hospital for partial implant-prosthetic rehabilitation on atrophic maxillary and/or mandibular sector. 13 implants were seated (85% in the maxilla) in the native bone then moved subsequently by segmental osteotomy. RESULTS The patients were assessed both clinically and radiologically according to the functional and aesthetic criteria of implant-prosthetic restoration. Functionally, a biomechanically favourable implant/number of teeth ratio (80%) was achieved, with consistent occlusal relationships (centric positioning of the midline point and absence of crossbite) in 100% of cases. Aesthetically, the screw access hole is systematically non-apparent (100%) but has a prosthetically substituted reduced gingivo-alveolar architecture. DISCUSSION These observations suggest that implant repositioning with segmental osteotomy allows for atrophic premaxilla restoration in implanted bone volume whatever the initial angulation. Peri-implant aesthetic difficulties are not specific to the technique suggested here but are quite common to all premaxilla reconstruction techniques. Lastly, this group of three patients is not enough to be conclusive, and a larger group would be necessary to validate this type of management.

Abstract
PURPOSE Development of minimally invasive therapies for temporomandibular joint osteoarthritis (TMJOA) has focused on drug intra-articular injections to avoid the systemic adverse effects experienced when these substances are administered orally. Therefore, we performed a systematic review to answer the question "Which method of induction of a TMJOA-related pain model in rats leads to prolonged painful symptoms, allowing the best assessment of a sustained drug delivery system?" MATERIALS AND METHODS Following the PRISMA guidelines, we searched MEDLINE for papers published from 1994 to July 2020 on a TMJ arthritis model using rats. We identified the means of pain induction and of nociception assessment. We assessed protocol bias using an adaptation of the QUADAS-2 tool. Animal selection, the reference standard method of pain assessment, applicability of a statistical assessment, and flow and timing were assessed. RESULTS Of the 59 full papers we reviewed, 41 performed no pain assessment after the first 7 days following induction of the TMJ-related pain model. We eventually identified 18 long-term TMJOA-related pain models. Pain was induced by injection of toxic substances, most commonly Freund's complete adjuvant (50 μg per 50 μl), formalin at various concentrations, or monosodium iodoacetate (0,5 mg per 50 μl), into the TMJ, or by physical methods. Few studies reported data on pain after 21 days of follow-up. Heterogeneity of induction methods, pain assessment methods, and flow and timing biases precluded a meta-analysis. CONCLUSIONS Given that pain is 1 of the main symptoms of TMJOA, experimental study protocols should include long-term pain assessment.

Abstract
During the 2020 coronavirus pandemic, a lockdown was imposed in France during the first wave. An apparent decrease in incidence of cellulitis of odontogenic origin was noticed then. This study aimed to compare the incidence of cellulitis during this extraordinary period with the same period in 2018 and 2019, based on retrospective multicentric data. All maxillofacial surgery departments in French public hospitals were contacted. Responders were asked to include all patients admitted for the surgical drainage of a head and neck abscess of odontogenic origin during the first 2020 lockdown period, and in a similar time frame in 2018 and 2019 (control group), based on screening the French diagnostic and therapeutic classification of medical acts. We report a 44% significant nationwide decrease in the incidence of admissions for cellulitis. There were 187 patients in 2020 for 334 and 333 patients in 2018/2019 respectively. The reasons to explain this finding are hypothetical (organizational reasons leading to earlier management, patients' fear to seek for medical management, usual excess in surgical indications or concomitant decrease of non-steroidal anti-inflammatory drugs delivery). Whatever the explanation, it would be of great interest to find it out in order to improve the prevention of cellulitis.

Abstract
PURPOSE Many technologies are emerging in the medical field. Having an overview of the technological arsenal available to train new surgeons seems very interesting to guide subsequent surgical training protocols. METHODS This article is a systematic approach reviewing new technologies in surgical training, in particular in oral and maxillofacial surgery. This review explores what new technologies can do compared to traditional methods in the field of surgical education. A structured literature search of PubMed was performed in adherence to PRISMA guidelines. The articles were selected when they fell within predefined inclusion criteria while respecting the key objectives of this systematic review. We looked at medical students and more specifically in surgery and analysed whether exposure to new technologies improved their surgical skills compared to traditional methods. Each technology is reviewed by highlighting its advantages and disadvantages and studying the feasibility of integration into current practice. RESULTS The results are encouraging. Indeed, all of these technologies make it possible to reduce the learning time, the operating times, the operating complications and increase the enthusiasm of the students compared to more conventional methods. The start-up cost, the complexity to develop new models, and the openness of mind necessary for the integration of these technologies are all obstacles to immediate development. The main limitations of this review are that many of the studies have been carried out on small numbers, they are not interested in acquiring knowledge or skills over the long term and obviously there is a publication bias. CONCLUSION Surgical education methods will probably change in the years to come, integrating these new technologies into the curriculum seems essential so as not to remain on the side. This first part therefore reviews, open field camera, telemedicine and 3D printing. This systematic review is registered on PROSPERO.

Abstract
OBJECTIVES There are few published studies evaluating the quality and outcome of multidisciplinary tumor board (MDTB) decisions. The aim of the present study was to evaluate adherence to MDTB recommendations in head and neck cancer and to document reasons in case of discordance. MATERIAL AND METHODS We included all patients with newly diagnosed head and neck cancer presented in our MDTB meetings between January 1st and December 31st, 2018, whatever the tumor site, histology type and TNM classification. MDTB recommendations were compared to actual treatment. Discordance was defined as treatment partially or entirely different from the treatment decision recorded in the MDTB minutes. RESULTS Board decisions were made for 344 new patients. Complete treatment concordance rate was 91.6% (315/344 patients), with deviation in 29 patients. Reasons for deviation were complications of treatment in 10 cases, patient refusal in 8, and physician's decision in 4 cases. Five patients died before therapy initiation. Mean interval from board discussion to treatment was 21 days, and depended on type of treatment (range, 1 to 74 days). CONCLUSION This study shows the importance of evaluating concordance between the protocol proposed in the MDTB and the treatment actually received, to identify factors for deviation and remedy them when possible.

Abstract
Benign and malign tumors can affect the temporomandibular joint (TMJ) as any other articulation. Nevertheless, TMJ tumors are rare and mostly benign. Their clinical expression is varied including symptomatology similar to TMJ dysfunctional disorders, otologic or neurologic pathologies. In some cases, they remain totally asymptomatic. Hence, diagnosis is difficult since the symptomatology can be misleading with TMJ dysfunctional disorders or otologic disorders wrongly diagnosed. There is thus frequently a long delay between symptoms onset and diagnosis. The great variety of TMJ lesions explains the wide range of possible treatment modalities, mostly based on surgery. We provide here a review of the lesions originating from the TMJ. Tumoral or cystic mandibular lesion affecting the TMJ through local extension will not be discussed. Osteoma, osteoid osteoma, osteoblastoma, chondroma, osteochondroma, chondroblastoma, tenosynovial giant cell tumors, giant cell lesions, non-ossifying fibroma, hemangioma, lipoma or Langerhans cell histiocytosis are all possible diagnosis among the benign tumors found in the TMJ. Pseudotumors include synovial chondromatosis and aneurysmal bone cyst. Finally, malign tumors of the TMJ include mainly sarcomas (osteosarcoma, chondrosarcoma, synovial sarcoma, Ewing sarcoma, and fibrosarcoma), but also multiple myeloma and secondary metastases. We will review the clinical, radiological and histological aspects of each of these lesions. The treatment and the recurrence risk will also be discussed.

Abstract
INTRODUCTION Cancer patients are particularly at risk for drug interactions. However, in oncology, this risk has not been studied in depth in France. The main objective of this study was to describe the proportion of drug interactions in patients with lung or digestive cancer. METHODS The drug prescriptions of 93 patients were analyzed from may 27th, 2019 to July 07th, 2019 using two software programs (Thériaque™ and DDI Predictor™) in oncology patients hospitalized in our comprehensive cancer center. RESULTS Of the 88 patients included in the study, 544 drug interactions were identified, in 66 patients (75.0%, 95% CI: 64.6-83.6). For 20/88 patients (22.7% CI: 14.5-32.9) a non-recommended combination or a theoretical contraindication was reported. Etoposide was the anticancer molecule most involved in combinations that are contraindicated or not recommended. No combinations defined as not recommended or contraindicated were observed in any of the 49 patients treated with chemotherapy during their hospitalization. The most common toxicities were alertness and metabolic disorders, including hyperkalemia. The use of three or more drugs was a risk factor for drug interactions (83 vs. 23%, P<0.001). CONCLUSION Drug interactions remain a major concern in cancer hospitalized patients. It is important to continue and strengthen the collaboration between physicians and pharmacists in order to better prevent their occurrence.

Abstract
Sickle cell disease (SCD) is a hemoglobin disorder characterized by the presence of abnormal haemoglobin. The deformed cells cause the blood to be more viscid, leading to vaso occlusive crises (VOC). We report an osteonecrosis of the jaw resulting of a VOC in a patient with sickle cell disease. Dental infections, particularly apical cysts, appear to be local factors favouring mandibular infarcts associated with sickle cell disease.

Abstract
There are numerous applications in craniofacial surgery with orbital volume (OV) modification. The careful management of the OV is fundamental to obtain good esthetic and functional results in orbital surgery. With the growth of computer-aided design - computer-aided manufacturing (CAD-CAM) technologies, patient-specific implants and custom-made reconstruction are being used increasingly. The precise measurement of the OV before surgery is becoming a necessity for craniofacial surgeons. There is no consensus on orbital volume measurements (OVMs). Manual segmentation of computed tomography (CT) images is the most used method to determine the OV, but it is time-consuming and very sensitive to operator errors. Here, we describe the various methods of orbital volumetry validated in the literature that can be used by surgeons in preoperative planning of orbital surgery. We also describe the leading software employed for these methods and discuss clinical use (posttraumatic enophthalmos prediction and orbital reconstruction) in which OVMs are important.

Abstract
The purpose of this technical note is to illustrate a simple and economical preoperative method for preshaping a reconstructive titanium plate in a fibula free flap (FFF) by using 3D printing of a virtually reconstructed mandible haptic model. The whole process consisted in creating a 3D model of the patient's mandible based on a CT-scan using a combination of free software (3Dslicer and ITK-snap), and simulating the surgical osteotomies and reconstruction, and print it as a guide for bending a reconstruction titanium plate. Reconstruction is performed using virtual cubes (1 to 3 cubes, according the number of FFF osteotomies). This virtual lab work is performed using 3D Builder® (Microsoft, Redmond) software. This technique allows obtaining an optimal plate application on the bony fragments. It facilitates reconstructive surgery with good functional (putting the patient back in an optimal dental occlusion based on the native maxilla) and aesthetic results. This technical note presents a simple and economical preoperative fabrication of a reconstructive plate through freeware and a low-cost 3D printer accessible to all surgeons.

Abstract
Craniofacial asymmetry, mandibular condylar modeling and temporomandibular joint disorders are common comorbidities of skeletally disproportionate malocclusions, but etiology of occurrence together is poorly understood. We compared asymmetry, condyle modeling stability and temporomandibular health in a cohort of 128 patients having orthodontics and orthognathic surgery to correct dentofacial deformity malocclusions. We also compared ACTN3 and ENPP1 genotypes for association to clinical conditions. Pre-surgical posterior-anterior cephalometric and panometric radiographic analyses; jaw pain and function questionnaire and clinical examination of TMD; and SNP-genotype analysis from saliva samples were compared to assess interrelationships. Almost half had asymmetries in need of surgical correction, which could be subdivided into four distinct morphological patterns. Asymmetric condyle modeling between sides was significantly greater in craniofacial asymmetry, but most commonly had an unanticipated pattern. Often, longer or larger condyles occurred on the shorter mandibular ramus side. Subjects with longer ramus but dimensionally smaller condyles were more likely to have self-reported TMD symptoms (p = 0.023) and significantly greater clinical diagnosis of TMD (p = 0 .000001), with masticatory myalgia most prominent. Genotyping found two significant genotype associations for ACTN3 rs1671064 (Q523R missense) p = 0.02; rs678397 (intronic SNP) p = 0.04 and one significant allele association rs1815739 (R577X nonsense) p = 0.00. Skeletal asymmetry, unusual condyle modeling and TMD are common and interrelated components of many dentofacial deformities. Imbalanced musculoskeletal functional adaptations and genetic or epigenetic influences contribute to the etiology, and require further investigation.
