Automatic Assessment of 3-Dimensional Facial Soft Tissue Symmetry Before and After Orthognathic Surgery Using a Machine Learning Model. LJ Lo, CT Yang, CT Ho, CH Liao, HH Lin.

This study applied the transfer learning model with a convolutional neural network based on 3-dimensional (3D) contour line features to evaluate the facial symmetry before and after OGS. A total of 158 patients were recruited in a retrospective cohort study for the assessment and comparison of facial symmetry before and after OGS from January 2018 to March 2020. Three-dimensional facial photographs were captured by the 3dMD face system in a natural head position, with eyes looking forward, relaxed facial muscles, and habitual dental occlusion before and at least 6 months after surgery.

Date: May 2020. Source: Thesis. Master of Science, The Faculty of Graduate and Postdoctoral Studies, Craniofacial Science, The University of British Columbia. Background: Prior to operative correction of a cleft lip, presurgical orthopaedics (PSO) with facial taping is used to improve pre-maxillary and soft tissue alignment. Two commercially available taping systems, Dynacleft and 3MTM taping…

Evaluation of Changes in Nasal Projection After Surgically Assisted Rapid Maxillary Expansion With 3dMDface System. MH Büyükçavuş, Y Findik, T Baykul.

Date: April 2020. Source: The Journal of Craniofacial Surgery. DOI: 10.1097/scs.0000000000006436. Abstract: The most appropriate treatment option for maxillary expansion in adulthood due to increased cyanosis in sutures is surgically assisted maxillary expansion (SARME). Skeletal and dental changes are observed with SARME. Three-dimensional imaging techniques are gaining importance with the developing technology in evaluating the…
