[Secondary reconstruction of the forehead defects].

The forehead is the protective helmet of the brain, if we refer to the etymology of the word calvaria. Destroyed, it must be rebuilt; priority is given to its bone infrastructure, even though we can live without it, as long as the other tissues (skin, muscle, aponeurosis, meninge) are intact. Complex surgical project which will be mentioned when the multiplicity of techniques described demonstrates their imperfection and until now the best restoration of a missing tissue requires its replacement by the same tissue.

Reconsideration of the alar base cinch suture technique involving the perinasal musculature: an in-depth review.

Orthognathic surgery affects both function and aesthetics. An important aesthetic complication is the nasal alteration that can result from Le Fort I osteotomy. A common method for countering this complication is the alar base cinch suture technique.

Impact of the COVID-19 Pandemic on Head and Neck Cancer Management: The Experience of the Maxillo-Facial Surgery Department of a French Regional Referral Center in a High-Incidence Area.

Cancer patients are at a high risk of complications in cases of infection, and head and neck cancers (HNC) are no exception. Since late 2019, SARS-CoV-2 has caused a global health crisis, with high rates and severe forms of the disease in cancer patients. Hospitalization, surgery and radiotherapy were rapidly described as increasing the risk of infection.

Evaluation of a Granular Bone Substitute for Bone Regeneration Using an Optimized In Vivo Alveolar Cleft Model.

Alveolar cleft is a common congenital deformity that requires surgical intervention, notably using autologous bone grafts in young children. Bone substitutes, in combination with mesenchymal stem cells (MSCs), have shown promise in the repair of these defects. This study aimed to evaluate the regenerative capabilities of a granular bone substitute using an optimized alveolar cleft model.

The Facial Graft: A Graft of Emotions? (About the Reanimation of the Facial Allotransplantation).

Although there have been numerous scientific papers reporting on composite allotransplantation of the face, few have been about assessment and evolution of the functional benefit for patients in terms of soft tissue mobility, movement coordination, and face expressions, even fewer on the choice of the surgical procedures to restore motricity. On some videos and interviews, it is possible to analyze significative motricity. Of course that has been voluntary motricity, not emotional motricity.

DeepSmile: Anomaly Detection Software for Facial Movement Assessment.

Facial movements are crucial for human interaction because they provide relevant information on verbal and non-verbal communication and social interactions. From a clinical point of view, the analysis of facial movements is important for diagnosis, follow-up, drug therapy, and surgical treatment. Current methods of assessing facial palsy are either (i) objective but inaccurate, (ii) subjective and, thus, depending on the clinician's level of experience, or (iii) based on static data.

Quantified analysis of facial movement: A reference for clinical applications.

Most techniques for evaluating unilateral impairments in facial movement yield subjective measurements. The objective of the present study was to define a reference dataset and develop a visualization tool for clinical assessments. In this prospective study, a motion capture system was used to quantify facial movements in 30 healthy adults and 2 patients.

Fast 3D Face Reconstruction from a Single Image Using Different Deep Learning Approaches for Facial Palsy Patients.

The 3D reconstruction of an accurate face model is essential for delivering reliable feedback for clinical decision support. Medical imaging and specific depth sensors are accurate but not suitable for an easy-to-use and portable tool. The recent development of deep learning (DL) models opens new challenges for 3D shape reconstruction from a single image.

Evaluation of Proton MR Spectroscopy for the Study of the Tongue Tissue in Healthy Subjects and Patients With Tongue Squamous Cell Carcinoma: Preliminary Findings.

Purpose: To noninvasively assess spectroscopic and metabolic profiles of healthy tongue tissue and in an exploratory objective in nontreated and treated patients with tongue squamous cell carcinoma (SCC).

Methods: Fourteen healthy subjects (HSs), one patient with nontreated tongue SCC (NT-SCC), and two patients with treated tongue SCC (T-SCC) underwent MRI and single-voxel proton magnetic resonance spectroscopy (H-MRS) evaluations (3 and 1.5T).

Masseteric nerve position on the "temporomandibular joint-chin tip" artificial axis: an anatomical study.

Purpose: The use of the masseteric nerve develops in the surgery of facial paralysis rehabilitation. The objective of this study was to determine the topography of the masseteric nerve and to deduce and predict a precise and reproducible anatomical cluster to facilitate its clinical identification during V-VII neurotization surgery.

Method: For the purpose of this work, a cadaveric study was performed on 31 hemi-faces.

Mass Spectrometry-Based Differentiation of Oral Tongue Squamous Cell Carcinoma and Nontumor Regions With the SpiderMass Technology.

Oral cavity cancers are the 15th most common cancer with more than 350,000 new cases and ~178,000 deaths each year. Among them, squamous cell carcinoma (SCC) accounts for more than 90% of tumors located in the oral cavity and on oropharynx. For the oral cavity SCC, the surgical resection remains the primary course of treatment.

Efficiency of advanced-PRF usage in the treatment of alveolar cleft with iliac bone graft: A retrospective study.

The aim of this study was to evaluate the efficiency of a new alveolar bone grafting protocol using advanced-PRF (a-PRF) by comparing the volumes of newly formed bone after a bone graft combining autogenous iliac crest bone with either PRF or a-PRF. Patients presenting with unilateral or a bilateral alveolar cleft were included retrospectively in two groups: one group was grafted using cancellous iliac crest bone with PRF (PRF group), whereas for the other group the same procedure was followed using a-PRF (a-PRF group). CBCT scans were performed 3 months preoperatively and 6 months postoperatively.

[Odyssey of the iliac. "Mandibular reconstruction by bone free flaps"].

The authors proposed here a retrospective analysis of a surgical procedure they performed for long time. It allows to put into questions some established principles, to find some unkwown datas which could be important to predict complications. It is also interesting to discuss about the use of indication and choice of the flaps along years of reconstructive surgery history in the way to improve protocoles and management of those large reconstruction.

Kinect-driven Patient-specific Head, Skull, and Muscle Network Modelling for Facial Palsy Patients.

Background And Objective: Facial palsy negatively affects both professional and personal life qualities of involved patients. Classical facial rehabilitation strategies can recover facial mimics into their normal and symmetrical movements and appearances. However, there is a lack of objective, quantitative, and in-vivo facial texture and muscle activation bio-feedbacks for personalizing rehabilitation programs and diagnosing recovering progresses.

Impact of the COVID-19 lockdown on the epidemiology of maxillofacial trauma activity: a French multicentre comparative study.

The coronavirus disease 2019 (COVID-19) outbreak has had a major impact on medical and surgical activities. A decline in facial trauma incidence was noticed during the lockdown period. The aim of this study was to evaluate the decline in maxillofacial trauma in France during this particular period.

Thrombotic Complications in Venous Malformations: Are There Differences Between Facial and Other Localizations?

Venous thrombosis (VT) is a frequent complication in venous malformations (VM) in relation with blood stasis and localized intravascular coagulopathy (LIC). Our aim was to describe the clinical characteristics and the treatment of patients with facial and non facial VM with VT. We implemented an observational retrospective study of patients with VM followed between 2002 and 2017.

Second metatarsal free transfer in total temporomandibular joint reconstruction for ankylosis in a child: 10-year follow-up.

The management of temporomandibular joint (TMJ) ankylosis requires complete removal of the ankylosed block and the prevention of recurrence. For this purpose, the ramus-condyle unit can be reconstructed with a second metatarsal free flap. This article reports the use of this flap in a young patient treated for left TMJ ankylosis, post costochondral graft for the treatment of hemifacial microsomia.

Use of an occlusal splint and intraoperative imaging with an intraoral approach in the management of mandibular subcondylar fractures.

Introduction: To evaluate the feasibility of safely managing subcondylar fractures using an original surgical procedure combining an intraoral approach, the use of a custom-made occlusal overlay splint, and intraoperative imaging.

Materials And Methods: Condylar fragment was freed from surrounding soft tissues, was laterally exposed to the ramus, and a miniplate was fixed in place for osteosynthesis. An overlay splint maintaining the dental occlusion was used to facilitate reduction and stabilization during fixation.

Genomics and precision surgery for head and neck squamous cell carcinoma.

The identification of the biological determinants that shape the response of tumors to medical therapies offers perspectives for better patient stratification and therapeutic targeting. Here, we discuss how genomics could help to improve the surgical treatment of head and neck squamous cell carcinoma (HNSCC). We examine the potential use of genomic analyses for: i) refining and standardizing the indications for surgery, ii) the choice of surgical procedure, and iii) the follow-up of patients with resected tumors.
