Posterior cranial vault distraction is a treatment for intracranial hypertension in certain cases of craniosynostosis and faciocraniosynostosis. It allows the harmonization of the skull back and prevents turricephaly. This study presents the surgical technique.

Posterior cranial vault distraction osteogenesis in craniofacial surgery: Technical note.

From its first descriptions in the early 1920s to today's use of cutting guides via computer-assisted surgery, surgical techniques to address hypertelorism have progressed. The present article aims to provide historical background and an overview of the development of surgical techniques during the late 20th century and in recent years. First, a historical overview identifies the most important surgical advances leading to the present state of the art. Each major surgical innovation is described, to explain the changes in this surgical field, according to the type of approach. Then, a precise description of today's most recent practices is provided, with particular emphasis on the spectacular advances deriving from computer-assisted surgery. A thorough description of the use of cutting guides throughout the surgical phase is given.

Addressing hypertelorism: Indications and techniques.

Treatment of craniosynostosis is complex and has greatly progressed in recent decades. From the early stages in the 1950s to today's most recent techniques, surgeons have faced the challenge of overcoming the deformities often caused by such invasive, complex surgeries. In the most recent years, new techniques have been developed that address surgical sequelae, including those of surgery performed in childhood. After a general introduction on craniosynostosis, the present paper describes the various types of deformity that may result from complex surgery and offers an overview of the various tools available to surgeons. An explanation of each indication and procedure is given.

Management of isolated and complex craniosynostosis residual deformities: What are the maxillofacial tools?

The reconstruction of segmental mandibular defects remains a challenge for the reconstructive surgeon, from both a functional and an esthetic point of view.

Reconstruction of segmental mandibular defects: Current procedures and perspectives.

Finding alternative strategies for the regeneration of craniofacial bone defects (CSD), such as combining a synthetic ephemeral calcium phosphate (CaP) implant and/or active substances and cells, would contribute to solving this reconstructive roadblock. However, CaP's architectural features (i.e., architecture and composition) still need to be tailored, and the use of processed stem cells and synthetic active substances (e.g., recombinant human bone morphogenetic protein 2) drastically limits the clinical application of such approaches. Focusing on solutions that are directly transposable to the clinical setting, biphasic calcium phosphate (BCP) and carbonated hydroxyapatite (CHA) 3D-printed disks with a triply periodic minimal structure (TPMS) were implanted in calvarial critical-sized defects (rat model) with or without addition of total bone marrow (TBM). Bone regeneration within the defect was evaluated, and the outcomes were compared to a standard-care procedure based on BCP granules soaked with TBM (positive control). After 7 weeks, de novo bone formation was significantly greater in the CHA disks + TBM group than in the positive controls (3.33 mm and 2.15 mm, respectively, P=0.04). These encouraging results indicate that both CHA and TPMS architectures are potentially advantageous in the repair of CSDs and that this one-step procedure warrants further clinical investigation.

Tailored Three-Dimensionally Printed Triply Periodic Calcium Phosphate Implants: A Preclinical Study for Craniofacial Bone Repair.

To identify the pathology causing the severe facial dysmorphia of a medieval individual from the site of Rigny (Indre-et-Loire, France) and to evaluate its functional repercussions on the subject's hearing and social life.

The aim of this retrospective monocentric study was to report the outcomes following the correction of post enucleation socket syndrome (PESS) as well as the factors predicting for a multistep management. Patients were included, if they had received surgery to manage PESS. Demographics and patient history were collected. The symptoms of PESS were clinically rated by the same surgeon and ocularist, preoperatively and after each procedure. The surgery was considered as successful when no PESS clinical symptoms were observed. A prognostic study was performed to investigate the surgical outcomes. RESULTS: Thirty-six patients were included and eight of them had their PESS corrected after the first surgery. In the multivariate analysis (MVA), the deep upper lid sulcus symptom remained the main significant factor associated with an incomplete correction after the first surgery (OR 45.5, IC 95% (3.481-594.6), p = 0.004). For further corrections, the ptosis was the only significant prognostic factor requiring several surgeries (p = 0.005). At the end of the management, 94.4% of the patients had satisfying outcomes. CONCLUSIONS: The management of a PESS involves the correction of both the orbital cavity and the soft tissues. Although its correction is complex and time consuming in the majority of cases, the patients should be informed that the final cosmetic outcomes remain good at the expense of several surgeries.

Management of post enucleation socket syndrome patients - A retrospective study.

In patients with Pfeiffer syndrome, several corrections are required to correct facial retrusion, maxillary deficiency, or even hypertelorism. The frontofacial monobloc advancement (FFMA) and the facial bipartition (FB) are the gold standard surgeries. We present the correction of this deformity using a simultaneous computer-assisted FFMA and FB.

Computer-Assisted Frontofacial Monobloc Advancement and Facial Bipartition for Pfeiffer Syndrome: Surgical Technique.

The MASK lift or subperiosteal lift of the upper and middle thirds of the face is a procedure that can be performed alone for aesthetic purposes, but can also be combined with reconstructive surgery of this region to improve the result. This procedure will enable the overall result to be enhanced in the management of complex pathologies. The aim of this article is to present the MASK lift surgical technique in detail, to explain its indications and to show that this surgical technique still has a place in our practice.
