    Abstract Objective: Evaluate the two-dimensional (2D) ultrasound (US) grid and multidisciplinary consultation (maxillofacial surgeon-sonographer) during prenatal US imaging to improve the sensitivity of prenatal description for cleft lip (CL) with or without alveolar cleft (CLA) or +/- cleft palate (CLP).
    Design: Retrospective study of children with CL/P in a tertiary children's Hospital.
    Setting: Single-center cohort study conducted in a tertiary pediatric Hospital.
    Patients/participants: Fifty-nine cases of prenatally diagnosed CL +/-CA or CP between January 2009 and December 2017 were analyzed.
    Main outcome measures: The correlation was analyzed between prenatal US and postnatal data with regard to eight 2D US criteria (upper lip, alveolar ridge, median maxillary bud, homolateral nostril subsidence, deviated nasal septum, hard palate, tongue movement, nasal cushion flux) in order to propose them in a grid, as well as the presence of the maxillofacial surgeon during the US examination.
    Results: Among the 38 cases included, the results were considered satisfied for 87%. Sixty five percent of the US criteria were described when the final diagnosis was correct (5.2 criteria) versus (vs) 45% (3.6 criteria); [OR = 2.28; IC95% (1.10-4.75)
    Conclusion: This US grid with eight criteria has considerably contributed to a more precise prenatal description. In addition, the systematic multidisciplinary consultation seemed to optimize it and lead to better prenatal information on pathology and postnatal surgical techniques.

    Abstract The Posterior vertical excess (PVE) associates a symmetric ramus and condyle elongation to an Angle Class III malocclusion. This dento-skeletal discrepancy can be isolated or associated to a condyle hyperplasia or a transverse overgrowth of the mandible due to macroglossia. We present the technique and the postoperative results of bilateral condylectomy applied for the surgical correction of PVE. Bilateral condylectomy represents an alternative to the bimaxillary surgery and adds to the therapeutic arsenal for the correction of Angle Class III malocclusion.

    Abstract Objectives: Among the existing techniques for the correction of mandibular posterior vertical insufficiency (PVI), the intra-oral ramus vertical lengthening osteotomy (IORVLO) can be proposed as it allows simultaneous correction of mandibular height and retrusion. This study assessed the 3D morpho-anatomical changes of the ramus-condyle unit and occlusal stability after IORVLO.
    Materials and methods: This retrospective analysis compared immediate and 1-year post-operative 3D CBCT reconstructions. The analysis focused on the condylar height (primary endpoint) and on the changes in condylar (condylar diameter, condylar axis angle) and mandibular (ramus height, Frankfort-mandibular plane angle, gonion position, intergonial distance, angular remodeling) parameters. Additionally, this analysis investigated the maxillary markers and occlusal stability.
    Results: On the 38 condyles studied in 21 included patients (mean age 23.7 ± 3.9 years), a condylar height (CH) loss of 0.66 mm (p < 0,03) was observed, with no correlation with the degree of ramus lengthening (mean 13.3 ± 0.76 mm). Only one patient presented an occlusal relapse of Class II, but a 3.4 mm (28%) condylar diameter loss and a 33% condylar volume reduction with loss of 1 mm and 3.4 mm in CH and condyle diameter, respectively. A mean 3.56 mm (p < 0.001) decrease in ramus height was noted, mainly due to bone resorption in the mandibular angles.
    Conclusion: This study confirms the overall stability obtained with IORVLO for the correction of PVI.
    Clinical relevance: This study aims to precise indication of IORVLO, and to validate the clinical and anatomical stability of results.

    Abstract Introduction: Recent microsurgical reconstruction techniques benefit from the use of skin and perforator flaps that spare the donor sites. Studies on these skin flaps in rat models are numerous but there is currently no reference regarding the position of the perforators, their caliber, and the length of the vascular pedicles.
    Methods: We performed an anatomical study on 10 Wistar rats and 140 vessels: cranial epigastric (CE), superficial inferior epigastric (SIE), lateral thoracic (LT), posterior thigh (PT), deep iliac circumflex (DCI) and posterior intercostal (PIC) vessels. The evaluation criteria were the external caliber, the length of the pedicle, and the position of the vessels reported on the skin surface.
    Results: Data from the six perforator vascular pedicles are reported, with figures illustrating the orthonormal reference frame, the representation of the vessel's position, the cloud of points corresponding to the various measurements, and the average representation of the collected data. The analysis of the literature does not find similar studies; the different vascular pedicles are discussed as well as the limitations of our study: evaluation of cadaver specimen, presence of the very mobile panniculus carnosus, other perforator vessels not evaluated as well as the precise definition of perforating vessels.
    Conclusions: Our work describes the vascular calibers, pedicle lengths, and location of birth and arrival at the skin of the perforator vessels PT, DCI, PIC, LT, SIE, and CE in rat animal models. This work, without an equivalent in the literature, lays the foundation for future studies about flap perfusion, microsurgery, and super microsurgery learning.

    Abstract This systematic review aimed to evaluate the dental prosthetic rehabilitation (DPR) in patients after jaw reconstruction with fibula free flap. Four databases were searched from January 2000 to January 2023. Of the 2507 studies identified, 36 observational studies were included. Cancer was the most common surgical indications for jawbone resection with 58.3 % of cases followed by benign tumours which representing 24 %. The DPR rate was estimated at 51.6 % across the studies (ranging from 38 % to 55 % depending on the benign or malignant nature of the tumors). Implant-supported prostheses represented 58.9 % of cases of which 66.9 % were fixed and 33.1 % were implant-stabilized overdentures. Virtual surgical planning (VSP) was used in 20 % of studies and aimed to improve the position of the grafted fibula, quality, and aesthetics of DPR and to decrease ischemia and the operating time. One in two authors performed DPR 12 months after jaw reconstruction. If implant survival rate reached 93 % in non-irradiated fibula, it fell to 38 %, 55 %, and 77 % if implantation occurred in the 12, 17, and 24 months after radiotherapy, respectively. Various parameters should be better investigated in further studies including the typology of the prostheses (implant-supported vs removable), the use of VSP, and the optimal time for DPR taking into account the characteristics of the tumor, the size of bone defect, and the need for external irradiation therapy.

    Abstract Introduction: Orbital floor fractures (OFF) are common facial trauma injuries, and there are no official guidelines for their medical and surgical management. The aim of this study was to provide an overview of the management of OFF in France.
    Materials and methods: An online questionnaire was sent to 144 surgeons at the 88 French centers involved in the management of OFF (2019 data from the National Health Insurance Body). The questions related to the preoperative clinical and radiographic examinations, the criteria for surgical indication, the materials used, and the elements of the postoperative period.
    Results: Ultimately, 42 questionnaires were analyzed (32 from oral and maxillofacial surgeons (OMFS), 8 from ophthalmologists, and 2 from ENT or plastic surgeons). For 69% of the surgeons, a systematic ophthalmological examination was carried out, 3-7 days after the trauma, and based on a Lancaster test or visual acuity (97.6% and 83.3% of the responders, respectively). The most important criteria for the therapeutic decision were diplopia or oculomotor disorder that persisted for more than 7 days (76.2%), clinical enophthalmos (54.8%), a large fracture (52.4%), and ptosis of the orbital content on CT scan (38.1%). The mean surgical delay was 7-15 days for 54.8% of the responders. Resorbing sheets were the preferred materials to repair small fractures, while larger fractures required alloplastic implants (titanium mesh).
    Conclusion: This survey confirms the diversity of practices in France regarding the management of OFF. Further studies are needed before guidelines can be developed.

    Abstract Introduction: We hypothesize that the removal of mandibular third molars (M3) 6 months prior to a bilateral sagittal split osteotomy (BSSO) could allow the displacement of the inferior alveolar nerve (IAN) in a favorable lingual position. This study aimed to radiographically compare the position of IAN before and after M3 removal in patients with Class II malocclusion.
    Materials and method: The CBCT images of 30 randomly selected patients (mean age 15.5 years, 19 females and 11 males) were segmented regarding the mandibular bone and the IAN canal. Mandibles were then superimposed and compared using 3D slicer (www.slicer.org). An orthonormal system was constructed, and the coordinates of IAN were assessed in the x- (horizontal axis), y- (depth axis), and z- (vertical axis) directions.
    Results: The mean changes in x- and z-values were 0.37 %, -0.09 % for the right IAN, 0.07 %, and -0.10 % for the left IAN, respectively. Y-axis was the dimension the most impacted by the M3 removal with a mean variation of -11.96 % for the right IAN, and 0.45 % for the left nerve (p
    Conclusion: This study confirms the absence of influence of mandibular third molar removal on the inferior alveolar nerve route prior to BSSO.

    Abstract Introduction: Functional genioplasty aims to achieve lip competence at rest and reduces lip pressure against the mandibular incisors. The purpose of this study was to describe the radiographic changes in alveolar bone of the mandibular incisors after functional genioplasty.
    Materials and methods: Cone beam CT images from 36 patients were compared between immediate (T0) and delayed postoperative period (T1). The mean time to complete the second imaging was 10.9 ± 4.7 months. Dental and bone parameters were assessed: the vestibular bone height (BH), the bone thickness (BT) with regard to the apex of the central incisor (BT2) and at equidistance between the cementoenamel junction and the dental apex (BT1). The existence of fenestrations, the apical-root resorption and the incisor-mandibular plane angle (IMPA) were also collected.
    Results: No significant change occurred in the BH. BT was improved of a mean 47.9% and 53.6% at the BT1 level on #31 and #41, respectively (p
    Conclusion: Functional genioplasty favours the alveolar bone formation of the mandibular central incisors, probably by direct bone grafting, but also by the relaxation of the perioral and chin musculature.

    Abstract Introduction: Craniofacial microsomia (CFM) and camel-hump condylo-mandibular dysplasia (CMD) are developmental disorders affecting the mandible that share common clinical features. This study aimed to investigate and compare the dental anomalies (DA) between the two entities for differential diagnosis and to propose appropriate treatment.
    Methods: This retrospective cross-sectional study was based on panoramic radiographs of patients diagnosed with CFM or CMD. DA were evaluated using the classification reported by Bilge. Delayed tooth eruption on the affected side was noted based on a comparison with the contralateral side. Nolla's stages of tooth calcification were used to assess dental development.
    Results: A total of 103 patients were included, 80 subjects (77.7 %) in CFM group and 23 patients (22.3 %) in CMD group. The prevalence of DA among CFM and CMD-affected patients were 80.0 % and 95.7 %, respectively. Tooth ectopia, tooth impaction, dental development delay, and delayed tooth eruption on the affected side exhibited a significant association with the two craniofacial malformations. The overall affected teeth (molars, premolars, canines) differed between the two craniofacial malformations. Dental abnormalities such as oligodontia, hyperdontia, dentin dysplasia, and anomalies of shape were seen only in subjects affected by CFM.
    Conclusion: DA were widely observed in patients with CFM and CMD. The global distribution of affected teeth differed between the two conditions and some DA were detected only in CFM patients. When clinical diagnosis remains uncertain, some specific radiological characteristics of DA can be used to differentiate CFM from CMD.
