Purpose: During the SARS-CoV-2 pandemic, higher education worldwide had to switch to digital formats. The purpose of this study was to evaluate CoRad-19, a digital teaching tool created by the German Radiological Society for medical students during the COVID-19 pandemic.
Materials And Methods: A total of 13 German-speaking universities implemented CoRad-19 in their curriculum and partially or completely replaced their classes with the online courses.
Purpose: Many genetic diseases are responsible for a defect in the growth of the maxilla. Craniofacial syndromes such as Crouzon syndrome or Apert syndrome are typically associated with a major hypoplasia in the midface responsible for exophthalmos, leading to palpebral malocclusion and frequent corneal complications. Several treatments have been used to manage ocular protection in craniofacial syndromes such as tarsorrhaphy, a fronto-orbital advancement and/or a Lefort III osteotomy with or without distraction.

Children operated from trigonocephaly between 2017 and 2019 at the French Referral Center for craniosynostosis of Femme-Mère-Enfant Hospital of Lyon, France, were included and separated in two groups. Group 1 included children operated on trigonocephaly using CAD-CAM technology; Group 2 included children operated on trigonocephaly without CAD-CAM technology.

Different surgical corrective techniques that aim to reshape the forehead and enlarge the cranial volume have been described. Typical variations of the standard fronto-orbitary advancement carry the risk of relevant blood loss during frontal osteotomy, where paired emissary metopic veins are disrupted.

Typically, they involve the long bones, commonly the tibia and the fibula, the vertebrae, and the sphenoid wing. The pathogenesis of NF-1 focal osseous lesions and its possible relationships with other osseous NF-1 anomalies leading to short stature are still unknown, though it is likely that they depend on a common mechanism acting in a specific subgroup of NF-1 patients.

However, for the healing process to occur, an inflammatory phase is also deemed necessary. Leukocytes present in the inflammatory phase release both pro- and anti-inflammatory molecules.

The technique involves an oblique supra-lingular osteotomy from internal to external, from top to bottom and from back to front. It is designed to divide the ramus into two segments, the joint and the mandibular body, and to ensure minimal valve equivalents.

Numerous surgical techniques have been proposed to enlarge and reshape the forehead. They all carry a risk of bleeding during osteotomies, especially in the region of the superior sagittal sinus (SSS) encased in the early fused suture and of the paired metopic transosseous emissary veins superior to the glabella, which is typical of this type of synostosis.

There are some important classifications to try to standardize the PRP procedure. The aim of this report is to describe PRP contents studying celular and molecular components, and also propose a new classification for PRP.

Extraction therapy can be a solution in case of excessive tooth volume and insufficient basal bone length. Techniques including bone distraction popularized by Ilizarov in the fifties allow the increase of the basal arch length in the maxilla as well as in the mandible.

Maxillofacial surgeons employ a variety of techniques, but treatment stability remains a common problem. This paper presents a range of therapeutic options with special emphasis on two little-known techniques for correcting transverse skeletal abnormalities: symphyseal distraction and mandibular constriction.
