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

Objectives: The development of 3D computer-assisted technologies over the past years has led to vast improvements in orthognathic surgery. The aim of the present study was to evaluate differences in maxillary position between 3D virtual surgical planning (VSP) and surgical results.

Materials And Methods: We assessed data from 25 patients who underwent bimaxillary non-segmented orthognathic surgery with 3D VSP.

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.

Outpatient orthognathic surgery: a prospective study of predictive factors for the length of hospital stays.

Objectives: Transitioning from non-outpatient orthognathic surgery to outpatient surgery is a new challenge, and it is essential to target the eligible population as precisely as possible. Several authors describe series of outpatient orthognathic surgery but do not include the reasons for their success or failure. The main aim of this study was to identify the factors significantly associated with "successful" outpatient orthognathic treatment.

Mandibular Titanium Miniplates Change the Biomechanical Behaviour of the Mandible in the Case of Facial Trauma: A Three-Dimensional Finite Element Analysis.

Our study aimed to compare the biomechanical behaviour of mandibles with or without titanium miniplates when subjected to an impact after bone healing using a finite element model (FEM) of the human mandible. We simulated mandibular trauma on an FEM of a human mandible carrying or not two parasymphyseal miniplates and applying a concentrated force of 2000 N to four different areas, including the insertion area, the area straddling the edge of the miniplates and the adjacent bone, at a distance from the miniplates on the symphysis, and on the basilar border of the mandible below the miniplates. Then, we compared the Von Mises stress distributions between the two models.

Photography in orthognathic surgery: A standardized protocol and storage legal implications.

Medical photography is an essential tool in orthognathic surgery to facilitate diagnosis, preoperative planning, and follow-up. Photographic documentation has clinical, research, teaching and legal applications. An accurate diagnostic approach and surgical planning of dentofacial deformity requires the ability to work with reproducible and measurable photographic images.

Botulinum toxin type A for the treatment of excessive gingival display - A systematic review.

Gummy smile has traditionally been treated with invasive or demanding surgical and orthodontic techniques. Several studies have shown that targeted injection of the upper lip elevator muscles with botulinum toxin is an effective treatment for this condition. However, no standardized injection protocol with reproducible results has yet been published.

Artificial intelligence for oral and maxillo-facial surgery: A narrative review.

Artificial Intelligence (AI) is a set of technologies that simulate human cognition in order to address a specific problem. The improvement in computing speed, the exponential production and the routine collection of data have led to the rapid development of AI in the health sector. In this review, we propose to provide surgeons with the essential technical elements to help them understand the possibilities offered by AI and to review the current applications of AI for oral and maxillofacial surgery (OMFS).

Sleep disturbances in early clinical stages of psychotic and bipolar disorders: A meta-analysis.

Objective: To provide a qualitative view and quantitative measure of sleep disturbances across and between early stages - clinical ultra high-risk and first episode - of psychotic and bipolar disorders.

Methods: Electronic databases (PubMed, Cochrane, Embase, PsychINFO) were searched up to March 2021 for studies comparing sleep measures between individuals with an early stage and controls. Standard mean deviations (Cohen's effect sizes) were calculated for all comparisons and pooled with random-effects models.

Wearable cardioverter-defibrillator in patients with a transient risk of sudden cardiac death: the WEARIT-France cohort study.

Aims: We aimed to provide contemporary real-world data on wearable cardioverter-defibrillator (WCD) use, not only in terms of effectiveness and safety but also compliance and acceptability.

Methods And Results: Across 88 French centres, the WEARIT-France study enrolled retrospectively patients who used the WCD between May 2014 and December 2016, and prospectively all patients equipped for WCD therapy between January 2017 and March 2018. All patients received systematic education session through a standardized programme across France at the time of initiation of WCD therapy and were systematically enrolled in the LifeVest Network remote services.

Conditions for the Implementation of a Patient Education Program Dedicated to Cancer Patients Treated by Oral Anticancer Therapy.

Introduction: A patient education program has been developed in the field of cancer for supporting cancer patients undergoing oral anticancer therapies. Its implementation was tested in 3 different settings. The objectives of this study were to 1) identify barriers and facilitators for implementing the patient education program, 2) identify practices encouraging or hindering implementation and 3) produce recommendations for its dissemination.

Simultaneous assessment of microcalcifications and morphological criteria of vulnerability in carotid artery plaque using hybrid F-NaF PET/MRI.

Background: Previous studies have suggested the role of microcalcifications in plaque vulnerability. This exploratory study sought to assess the potential of hybrid positron-emission tomography (PET)/magnetic resonance imaging (MRI) using F-sodium fluoride (F-NaF) to check simultaneously F-NaF uptake, a marker of microcalcifications, and morphological criteria of vulnerability.

Methods And Results: We included 12 patients with either recently symptomatic or asymptomatic carotid stenosis.

Onychomycosis and AIDS. Clinical and laboratory findings in 62 patients.

The results of a study on onychomycosis in AIDS related complex and AIDS patients presenting for dermatology consultation at an infectious diseases department are reported. The clinical results showed that most patients presented a proximal white superficial onychomycosis. The association with a clinical interdigital involvement was rare, but the association with a mycotic plantar keratoderma was more frequent.
