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…

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…

Learning to Rank the Severity of Unrepaired Cleft Lip Nasal Deformity on 3D Mesh Data. J Wu, R Tse, LG Shapiro.

Date: August 2014. Source: Int. Conference on Pattern Recognition (ICPR) 2014, Stockholm, Sweden. © IEEE. Pages 460-464. Abstract: Cleft lip is a birth defect that results in deformity of the upper lip and nose. Its severity is widely variable and the results of treatment are influenced by the initial deformity. Objective assessment of severity would…

Date: July 2014. Source: Journal of Craniofacial Surgery, 25(4):1178-82. Background: Deformational plagiocephaly (DP) is an asymmetry of the skull caused by extrinsic compression. With the advent of the Back to Sleep campaign, DP is of increased interest to parents and healthcare providers. Traditionally, this asymmetry has been assessed by caliper measurements. However, little consensus exists…

Date: July 2014. Source: Journal of Craniofacial Surgery, 25(4):1365-8. Abstract: Positional plagiocephaly (deformational or occipital plagiocephaly) is the most common head-shape deformity, which is presented to specialist craniofacial units. The aim of management is to reduce pressure on the affected area in the expectation that brain growth will drive normalization of the head shape. Current…

Abstract: Family relatives of children with nonsyndromic cleft lip with or without cleft palate (NSCL/P) who presumably carry a genetic risk yet do not manifest overt oral clefts, often present with distinct facial morphology of unknown genetic etiology. This study investigates distinct…
