Comparative Analysis of Three-Dimensional Nasal Shape of Casts from Patients With Unilateral Cleft Lip and Palate Treated at Two Institutions Following Rotation Advancement Only (Iowa) or Nasoalveolar Molding and Rotation Advancement in Conjunction With Primary Rhinoplasty (New York). B Hosseinian, MS Rubin et al.

Date: November 2018. Source: Cleft Palate-Craniofacial Journal, Volume 55, issue 10, pp 1350-1357. Objective: To compare 3-dimensional nasal symmetry in patients with UCLP who had either rotation advancement alone or nasoalveolar molding (NAM) followed by rotation advancement in conjunction with primary nasal repair.

Three-dimensional evaluation of social smile symmetry. GS Duran, F Dindaroğlu, S Görgülü.

Date: January 2017. Source: The Angle Orthodontist: Vol. 87, No. 1, pp. 96-103. Objective: To evaluate the social smile symmetry using three-dimensional (3D) stereophotogrammetric images. Materials and Methods: The study was conducted with 3D facial images of 30 individuals (age range 13–25 years). The rest position was considered as the reference image and the social…

Measuring Symmetry in Children With Cleft Lip. Part 3: Quantifying Nasal Symmetry and Nasal Normalcy Before and After Unilateral Cleft Lip Repair. S Liang, L Shapiro, R Tse.

Date: October 2016 (Online). Source: The Cleft Palate-Craniofacial Journal. Objective: The purpose of this project was to develop objective computer-based methods to measure nasal asymmetry and abnormality in children undergoing treatment of unilateral cleft lip (UCL) and to determine the correlation of these measures to clinical expectations. Participants: Thirty infants with UCL undergoing cleft lip…

Quantification of facial asymmetry: A comparative study of landmark-based and surface-based registrations. T Verhoeven, T Xic, R Schreurs, S Bergé, TJJ Maal.

Date: September 2016. Source: Journal of Cranio-Maxillo-Facial Surgery, Volume 44, Issue 9, Pages 1131–1136. Objective: To compare the validity and reproducibility of four different methods for the quantification of soft tissue facial asymmetry. Methods: Twenty 3D-photographs were randomly selected from the healthy control database. To assess the validity of the one landmark-based and three surface-based…

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…

3D Symmetry Measure Invariant to Subject Pose During Image Acquisition. M Kawale, J Lee, SY Leung, MC Fingeret, GP Reece, MA Crosby, EK Beahm, MK Markey, FA Merchant.

Date: June 2011. Source: Breast Cancer (Auckl). 5:131-42. doi: 10.4137/BCBCR.S7140. Abstract: In this study we evaluate the influence of subject pose during image acquisition on quantitative analysis of breast morphology. Three (3D) and two-dimensional (2D) images of the torso of 12 female subjects in two different poses; (1) hands-on-hip (HH) and (2) hands-down (HD) were…
