Background/Objectives: Misdiagnosing skin disorders leads to the administration of wrong treatments, sometimes with life-impacting consequences. Deep learning algorithms are becoming more and more used for diagnosis. While many skin cancer/lesion image classification studies focus on datasets containing dermatoscopic images and do not include keloi...

Medication-related osteonecrosis of the jaw (MRONJ) is a complication caused by anti-resorptive agents and anti-angiogenesis drugs. Since we wanted to write a protocol for a randomized clinical trial (RCT), we reviewed the literature for the essential information needed to estimate the size of the active patient population and measure the effects o...

Objectives: The purpose of this pilot porcine study was to explore and illustrate the surgical application of human amniotic membrane (hAM) in an ex vivo model of medication-related osteonecrosis of the jaw (MRONJ). Material and methods: Five oral and maxillofacial surgeons participated to this study. MRONJ was simulated on porcine mandible specime...

This study aimed to demonstrate an association between the occurrence of surgical site infection (SSI) after orthognathic surgery and penicillin allergy and to assess whether other factors could be associated with the occurrence of SSI. A 10-year monocentric retrospective study was conducted to identify possible risk factors for SSI in orthognathic...

Medication-related osteonecrosis of the jaw (MRONJ) is a complication of certain pharmacological treatments such as bisphosphonates, denosumab, and angiogenesis inhibitors. There are currently no guidelines on its management, particularly in advanced stages. The human amniotic membrane (hAM) has low immunogenicity and exerts anti-inflammatory, anti...

Due to its intrinsic properties, there has been growing interest in human amniotic membrane (hAM) in recent years particularly for the treatment of ocular surface disorders and for wound healing. Herein, we investigate the potential use of hAM and amnion-chorion membrane (ACM) in oral surgery. Based on our analysis of the literature, it appears tha...

Aim To evaluate the impact of intraoperative cone beam computed tomography (CBCT) assessment for the surgical management of zygomatic bone fracture (ZF). Methods A prospective study was conducted on patients operated on for unilateral ZF during a two-year period. Repositioning of the fractured zygoma was assessed intraoperatively by measuring the...

The aim of this study was to evaluate the diagnostic accuracy of mobile cone beam computed tomography (MCBCT) versus multi-detector computed tomography (MDCT) in orbital floor fractures. Twenty-four fresh cadaver heads were used, and one orbital floor was fractured for each head by transconjunctival approach. MDCT and MCBCT were performed on each o...

Intraoperative imaging is increasingly used by surgeons and has become an integral part of many surgical procedures. This study was performed to provide an overview of the current literature on the intraoperative use of cone beam computed tomography (CBCT) imaging in maxillofacial surgery. A bibliographic search of PubMed was conducted in March 202...

Mycoplasma pneumoniae induced rash and mucositis (MIRM) is a distinct entity of erythema multiforma spectrum. Observation: we report a case of a 19-year-old man hospitalised for multiple mucosal eruptions and hyperthermia for three days, in context of a pro-T lymphoblastic leukemia in complete cytological and molecular remission. Discussion: MIRM i...

Introduction: 3D-printing seems to have more and more applications in maxillofacial surgery (MFS), particularly since the release on the market of general use 3D-printers several years ago. The aim of our study was to answer 4 questions: 1. Who uses 3D printing in MFS and is it routine or not? 2. What are the main clinical indications for 3D-print...

Introduction: Wisdom teeth extraction is a common procedure, generally considered as safe by patients. However, complications are possible, especially periodontal ones. The aim of this study was to evaluate the frequency and the consequences of periodontal complications at the level the 2nd molars after extraction of the wisdom teeth. Material an...

L’arthrocentèse de l’articulation temporomandibulaire associée à un lavage intra-articulaire et, plus récemment, à l’injection intra-articulaire d’un agent pharmacologique a été développée à partir des années 1990 et est largement utilisée de nos jours pour le traitement des dysfonctions temporomandibulaires (DTM). Le but de notre travail était de...

Introduction: Craniosynostoses affecting the forehead sutures can not only cause brain damage, but can also have an esthetic impact, because of the associated orbito-naso-frontal deformations. Reshaping the orbito-naso-frontal bandeau (ONFB) is difficult to appreciate perioperatively and should ideally be customized to each child. The aim of this...

Introduction: Craniosynostoses are cranio-facial malformations affecting about 1/2100 newborns in France. The involvement of anterior sutures (coronal and metopic) leads to orbito-frontal deformities. The treatment calls upon surgery the goal being, on an esthetic point of view, to restore a normal anatomy. The purpose of our work was to establish...

Résumé Introduction L’ankylose temporo-mandibulaire osseuse est responsable, lorsqu’elle survient dans l’enfance, de déformations maxillo-faciales complexes, notamment d’un manque de croissance mandibulaire. Nous présentons un cas d’ankylose temporo-mandibulaire associée à une asymétrie mandibulaire sévère traitée par distraction mandibulaire prem...

L’utilisation de membranes en chirurgie pré-implantaire s’intègre dans le concept de régénération osseuse guidée (ROG), l’une des techniques classiques d’augmentation osseuse. La membrane en ROG a deux fonctions essentielles : un rôle mécanique de maintien de l’espace de régénération et un rôle physique de barrière cellulaire. Le but est de favoris...

The use of membranes in pre-implantation surgery is part of the guided bone regeneration (GBR) concept, one of the usual bone augmentation techniques. Membranes for GBR procedures have two main uses: a mechanical function to maintain bone regeneration space and a physical function as cellular barrier. The goal is to promote colonization of the rege...

Introduction Hyalinizing clear cell carcinoma (HCCC) of minor salivary glands (MSG) is a rare low-grade malignant neoplasm accounting for less than 1% of all salivary gland tumors. It usually affects the palate and the base of the tongue, and more rarely the parotid gland. We report a very rare maxillary localization. Case report A 48-year-old mal...

Introduction: False aneurysms of the superficial temporal artery (STA) are rare and usually occur after a direct trauma to one of its branches. It is characterized by the local rupture of the artery wall. The diagnosis is made by clinical history and clinical examination. The treatment is surgery.

Unlike severe head injuries upon which much attention is focused, mild or moderate brain injuries are not or not well known and often neglected in maxillofacial surgery. Nevertheless, they are frequent in our routine facial traumatology activity. Studying the epidemiological data shows that mild brain injuries account for 64 to 94% of all head inju...

Physicians are often asked to draft a descriptive medical certificate for victims of traumatic maxillofacial injuries. Among other requisites, this certificate must mention the subject's total work disability. If the injury results from intentional or unintentional assault and battery, the duration of the work disability will determine the competen...

Contrairement aux traumatisés crâniens graves qui sont au centre de toutes les attentions, les traumatisés crâniens légers (TCL) ou modérés (TCM) ne sont pas ou peu connus voire négligés en chirurgie maxillo-faciale. Pourtant, la traumatologie faciale représente au moins le tiers de l’activité opératoire d’un service hospitalier.L’étude des données...
