Three-dimensional acquisition technologies for facial soft tissues - Applications and prospects in orthognathic surgery.

Dec, 2020

The management of patients with dento-maxillofacial deformities is based on assessments of the dental occlusion - facial skeleton - soft tissues triad. As societal demands and surgical practices have evolved, facial soft tissues have moved to the forefront of considerations in orthognathic surgery. Techniques are therefore required to analyze facial soft tissues objectively and reproducibly, for diagnosis, preoperative planning, and follow-up. Several technologies are currently capable of providing three-dimensional (3D) models of the face, either by 3D reconstruction of traditional computed tomography or cone beam computed tomography data, or directly by stereophotogrammetry, laser scanning or structured light scanning. Multimodal image registration techniques allow bone base, dental occlusion and facial soft tissue information to be combined in a 3D virtual patient. Three-dimensional cephalometric analysis of the facial skeleton and skin is now perfectly integrated in virtual planning and is gradually gaining in automation and accuracy. Photorealistic 3D simulations allow optimal soft tissue planning and facilitate physician-patient communication. Finally, these facial modeling techniques facilitate post-operative studies of soft tissues, which generally involve comparisons of volumetric data. There are many research avenues to pursue and technical improvements are to be expected, particularly through the development of big data and artificial intelligence approaches. leer más

Spontaneous rupture of an aneurysm of the superior thyroid artery: A rare cause of acute respiratory failure.

Dec, 2020

Ruptured aneurysm of superior thyroid artery is a very rare pathological event. Underlying causes such as trauma, malignancy or iatrogenic are not systematically found. Resulting cervical hematoma is life threatening and can lead to acute respiratory failure, dysphagia, vocal cord paralysis and hemomediastinum. Endovascular treatment combined with surgical drainage has been described as an effective treatment. In this case report, a 63-year-old man presented a spontaneous rupture of an aneurysm of superior thyroid artery resulting in cervical hematoma and acute respiratory failure. leer más

Many surgical instruments are named after their inventors, acclaimed surgeons of the past, because of their discoveries and their contributions in the field of surgical techniques. However, these daily reminders of history of surgery are often forgotten by the modern practitioners. We propose to review, through a selection of instruments, short biographies of these precursors. This fourth original article will focus on the inventors of rhinoplasty instruments: Joseph, Killian, Aufricht, Cottle and Claoué. leer más
