AN UPDATED OVERVIEW OF ORTHOGNATHIC SURGERY PRACTICES IN FRANCE.

Introduction: Orthognathic surgery is a fundamental component of a maxillofacial surgeon's practice. In France, 510 specialists actively practice oral and maxillofacial surgery. In OMFs, despite the existence of evidence-based recommendation that address diagnosis, treatment planning, and operating methods, each surgeon/institution has developed an individual approach towards clinical management.

Assessing Dental Implant Success: A Systematic Review and Meta-Analysis of Primary Versus Secondary Implantation in Free Bone Flap Reconstruction for Malignant Tumors.

Background: Dental implantation of bone reconstructions in oncologic situations improves patients' orofacial function and quality of life. There are currently no recommendations on the timing of implantation.

Methods: This systematic review with meta-analysis aimed to compare primary and secondary dental implantation of free bone flaps in reconstructions for malignant tumors of the oral cavity.

Ossifying fibroma and juvenile ossifying fibroma: A systematic review on clinical and radiological parameters, treatment modalities and recurrence.

Ossifying fibroma (OF) is a rare benign fibro-osseous neoplasm developing mostly in maxillo-facial bones. OF is divided in cemento-ossifying fibroma (COF), juvenile trabecular ossifying fibroma (JTOF) and psammomatoid ossifying fibroma (PSOF). The aim of this systematic review was to synthetize the existing literature on OF, investigating the clinical and radiological parameters related to the different forms of the disease, and to compare the treatment modalities according to their associated recurrence rate.

Measurement of Cumulative Drug Exposure from Clinical Data Warehouse.

Polypharmacy (PP) and hyperpolypharmacy (HPP), are prevalent among cancer patients and are associated with an increased risk of drug-drug interactions (DDI) and potentially inappropriate medications (PIM). This study aimed to characterize PP, HPP, DDI, and PIM in patients with hematological malignancies hospitalized for hematopoietic stem cell transplantation (HSCT) by introducing a novel metric: cumulative drug exposure. Clinical data warehouse (CDW) records were employed to develop algorithms that quantified patients' cumulative exposure to these prescribing determinants during hospitalization.

Virtual surgical planning in orthognathic surgery: A prospective evaluation of postoperative accuracy.

Low dose of propyl-pyrazole-triol, an agonist of estrogen receptor alpha, administration stimulates the Coolidge effect in fadrozole-treated male rats.

Estrogen receptor (ER) α is involved in male sexual function. Here, we aim to investigate how ERα activation influences sexual satiety and the Coolidge effect (i.e.

Application of bilateral condylectomy as an alternative surgical treatment for Class III malocclusion with posterior vertical excess, a technical note.

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.

3D analysis of condylar and mandibular remodeling one year after intra-oral ramus vertical lengthening osteotomy.

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.

Evaluation of the efficacy of a custom-made monoblock mandibular advancement device in treatment of obstructive sleep apnea hypopnea syndrome.

Introduction: Mandibular advancement devices (MAD) are an alternative to continuous positive airway pressure for the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS). We aimed to evaluate the efficiency of a custom-made monoblock MAD for the treatment of OSAHS.

Materials And Methods: We carried out a monocentric retrospective observational study including patients with OSAHS (mild, moderate or severe) or isolated ronchopathy from January 2005 to March 2023.

Prosthetic rehabilitation in patients with jaw reconstruction by fibula free flap: A systematic review.

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.

Radiological evaluation of inferior alveolar nerve displacement after removal of impacted mandibular third molars prior to sagittal split osteotomy.

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.

AI-based diagnosis in mandibulofacial dysostosis with microcephaly using external ear shapes.

Introduction: Mandibulo-Facial Dysostosis with Microcephaly (MFDM) is a rare disease with a broad spectrum of symptoms, characterized by zygomatic and mandibular hypoplasia, microcephaly, and ear abnormalities. Here, we aimed at describing the external ear phenotype of MFDM patients, and train an Artificial Intelligence (AI)-based model to differentiate MFDM ears from non-syndromic control ears (binary classification), and from ears of the main differential diagnoses of this condition (multi-class classification): Treacher Collins (TC), Nager (NAFD) and CHARGE syndromes.

Methods: The training set contained 1,592 ear photographs, corresponding to 550 patients.

Stability of Le Fort 1 osteotomy in patients with bilateral cleft lip and palate: A retrospective study of 71 patients.

Background: Imaging of the salivary ductal system is relevant prior to an endoscopic or a surgical procedure. Various imaging modalities can be used for this purpose. The aim of this study was to compare the diagnostic capability of three-dimensional (3D)-cone-beam computed tomography (CBCT) sialography versus magnetic resonance (MR) sialography in non-tumorous salivary pathologies.

Leveraging Clinical Data Warehouses to Measure Impact of Update Prescription Guidelines of Polyvalent Immunoglobulins in 2018 in France.

In France and in other countries, we observed a significant growth in human polyvalent immunoglobulins (PvIg) usage. PvIg is manufactured from plasma collected from numeral donors, and its production is complex. Supply tensions have been observed for several years, and it is necessary to limit their consumption.

Long-term vertical stability of horseshoe osteotomy for the correction of large vertical excess of the maxilla, a retrospective assessment in 15 patients.

Introduction: Vertical stability after a Le Fort I (LF1) osteotomy with substantial upward movement can be compromised by the position and the volume of the inferior turbinate. A horseshoe (HS) osteotomy represents then an alternative as it preserves the hard palate and the intranasal volume. The aim of this study was to assess the vertical stability of the maxilla after HS osteotomy.

Rat Perforator and Skin Vessels Vascular Mapping: An Original Anatomical Study About 140 Vessels and Literature Review.

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.
