Date: February 2015. Source: Orthodontics & Craniofacial Research, 18(1):21-6. Objectives: Several reports have demonstrated a relationship between second to fourth digit ratio (2D:4D) and facial shape, suggesting that prenatal sex hormones play a role in the development of the craniofacial complex. Using 3D surface imaging and geometric morphometrics, we test the hypothesis that decreased digit…

Date: February 2015. Source: The European Journal of Orthodontics. Objectives: Assess facial asymmetry in subjects with unilateral cleft lip (UCL), unilateral cleft lip and alveolus (UCLA), and unilateral cleft lip, alveolus, and palate (UCLP), and to evaluate which area of the face is most asymmetrical. Methods: Standardized three-dimensional facial images of 58 patients (9 UCL,…

Date: February 2015. Source: The Cleft Palate-Craniofacial Journal. Abstract: In severe syndromic craniosynostosis, distraction osteogenesis (DO) provides superior segmental advancement and allows progressive clinical monitoring to ensure that adequate skeletal expansion is achieved. We report two cases of Crouzon syndrome involving a 3-year-old boy and a 4-year-old girl, who were both treated with monobloc Le…

Date: December 14-16, 2014. Source: 2014 ASE BigData/SocialInformatics/PASSAT/BioMedCom 2014 Conference, Harvard University. Abstract: We describe a novel automatic computational framework for evaluating and visualizing the results of infant cranial surgeries. We begin by capturing a 3D triangle mesh of the subject’s head using a 3dMD camera. Our framework includes a mesh decimation algorithm to simplify…

Reliability and validity of measurements of facial swelling with a stereophotogrammetry optical three-dimensional scanner. WJ van der Meer, PU Dijkstra, A Visser, A Vissink, Y Ren.

Date: December 2014 Source: British Journal of Oral Maxillofacial Surgery, 52(10):922-7. Abstract: Volume changes in facial morphology can be assessed using the 3dMDface® stereo-optical 3-dimensional scanner, which uses visible light and has a short scanning time. Its reliability and validity have not to our knowledge been investigated for the assessment of facial swelling. Our aim…

Quantitative Assessment of Facial Asymmetry Using Three-Dimensional Surface Imaging in Adults: Validating the Precision and Repeatability of a Global Approach. D Kornreich, AA Mitchell, BD Webb, I Cristian, EW Jabs.

Date: December 2014. Source: The Cleft Palate-Craniofacial Journal. Objective: Comparison of global versus landmark analyses of facial asymmetry using three-dimensional photogrammetry to establish a precise method for evaluating facial asymmetry. Design: The landmark-based approach utilized anthropometric data points. Our global approach involved registration of mirror images, independent of a midplane, to calculate a root mean…

Date: November 2014 Source: Journal of Oral and Maxillofacial Surgery, 72(11): 2256-61. Abstract: The purpose of this study was to develop a technique to record physical references and orient digital mesh models to a natural head position using stereophotogrammetry (SP). The first step was to record the digital mesh model of a hanging reference board…

Date: October 2014. Source: Artificial Intelligence in Medicine, 62(2):105-18. Background: In general, medical geneticists aim to pre-diagnose underlying syndromes based on facial features before performing cytological or molecular analyses where a genotype–phenotype interrelation is possible. However, determining correct genotype–phenotype interrelationships among many syndromes is tedious and labor-intensive, especially for extremely rare syndromes. Thus, a computer-aided…
