Measuring Symmetry in Children With Unrepaired Cleft Lip: Defining a Standard for the Three-Dimensional Mid-facial Reference Plane. J Wu, C Heike, C Birgfeld, K Evans, M Maga, C Morrison, B Saltzman, L Shapiro, R Tse.

Date: March 2016 (Online ahead of print) Source: The Cleft Palate-Craniofacial Journal. Objective: Quantitative measures of facial form to evaluate treatment outcomes for cleft lip (CL) are currently limited. Computer-based analysis of three-dimensional (3D) images provides an opportunity for efficient and objective analysis. The purpose of this study was to define a computer-based standard of […]

Measuring Symmetry in Children With Cleft Lip. Part 2: Quantification of Nasolabial Symmetry Before and After Cleft Lip Repair. J Wu, S Liang, L Shapiro, R Tse.

Date: December 2015. Source: The Cleft Palate-Craniofacial Journal. Objective: The first part of this study validated an automated computer-based method of identifying the three-dimensional midfacial plane in children with unrepaired cleft lip. The purpose of this second part is to develop computer-based methods to quantify symmetry and to determine the correlation of these measures to […]
