Date: October 2018. Source: The Angle Orthodontist. Objective: To investigate the influence of cheek volume on facial esthetics judged by orthodontists and non-specialists. Materials and Methods: A 25-year-old female’s natural and smiling face was captured by 3D stereophotogrammetry. Cheek volume of the 3dMD image was altered to different degrees three-dimensionally. For the natural and smiling…

Date: October 2018. Source: Journal of Neurosurgery: Pediatrics [Online Before Print]. Objective: Metrics used to quantify preoperative severity and postoperative outcomes for patients with sagittal synostosis include cephalic index (CI), the well-known standard, and the recently described adjusted cephalic index (aCI), which accounts for altered euryon location. This study tracks the time course of these…

Date: October 2018. Source: European Journal of Plastic Surgery, Volume 41, Issue 5, pp 571–576. Background: Over the last years, several techniques have been proposed to improve the outcome of autologous breast reconstruction procedures. One of these innovations describes patient-specific, three-dimensional (3D) printed breast molds for intraoperative use based on 3D stereophotogrammetry. In this article,…

Date: September 2018. Source: Sports Engineering, Volume 21, Issue 3, pp 217–225. Abstract: In snowboarding, the wrist is the most common injury site, as snowboarders often put their arms out to cushion a fall. This can result in a compressive load through the carpals coupled with wrist hyperextension, leading to ligament sprains or carpal and…

Reconstruction of the oral commissure in patients with unilateral transverse facial cleft. M Tuersunjiang, X Long, Y Fu, J Ke, H He, J Li.

Date: September 2018. Source: British Journal of Oral and Maxillofacial Surgery, Volume 56, Issue 7, pp 621-625. Abstract: The normal commissure is not a simple joint of the upper and lower lip, but a triangular mucosal area. To reconstruct a symmetrical oral commissure in patients with a unilateral transverse facial cleft, we designed composite vermilion…
