In-house 3D printing: Why, when, and how? Overview of the national French good practice guidelines for in-house 3D-printing in maxillo-facial surgery, stomatology, and oral surgery.

3D-printing is part of the daily practice of maxillo-facial surgeons, stomatologists and oral surgeons. To date, no French health center is producing in-house medical devices according to the new European standards. Based on all the evidence-based data available, a group of experts from the French Society of Stomatology, Maxillo-Facial Surgery and Oral Surgery (Société Française de Chirurgie Maxillofaciale, Stomatologie et Chirurgie Orale, SFSCMFCO), provide good practice guidelines for in-house 3D-printing in maxillo-facial surgery, stomatology, and oral surgery.

Neurodevelopmental outcome at 24 months of healthy infants at birth with an umbilical artery blood pH ≤ 7 and/or hyperlactacidemia ≥ 7 mmol/L.

Objective: The incidence of acidosis in term and healthy newborns and the consequences for their neurodevelopment are poorly understood. The aim of our study was to assess neurodevelopmental outcomes at 24 months of age via a parental questionnaire (ASQ, Ages and Stages Questionnaires) for a sample of infants born at term with an umbilical arterial blood pH ≤ 7 or/and hyperlactacidemia ≥ 7 mmol/L. In addition, we compared these groups' neurodevelopmental outcomes with a control group.

Bilateral sagittal split osteotomy training on mandibular 3-dimensional printed models for maxillofacial surgical residents.

Complications with bilateral sagittal split osteotomy (BSSO) can sometimes result from surgical inexperience. Our aim was to present a 3-dimensional printed mandibular model for BSSO training in a maxillofacial surgical education programme. A polymethacrylate mandibular model obtained from mandibular cone-beam computed tomographic (CT) images was designed and printed for use in training.

Conception and use of a custom-made facial mask for pressure therapy in complex facial wounds.

Pressure therapy (PT) is commonly used to manage hypertrophic scars. It is often based on the use of elastic pressure garments, which are poorly suited for a facial localization. We describe the conception, fabrication, and use of a custom-made PT facial mask for primary prevention of hypertrophic scarring of complex facial wounds.

Vertical lengthening genioplasty: A new osteotomy technique.

Vertical insufficiency of the chin imbalances the orofacial and aesthetic parameters of the lower third of the face. We here propose a new osteotomy technique for chin lengthening. Our procedure is based on a single osteotomy and it does not require any interposition of a bone graft.
