Evolutionary analyses suggest that the difference in nose shape between EUR and EAS populations is caused by a directional selection, due mainly to a local adaptation in Europeans. Our results illustrate the underlying genetic basis for facial differences across populations.

Date: September 15, 2015. Source: 16th Congress of International Society of Craniofacial Surgery (ISCFS) 2015. Presenter: C Duncan. Introduction: Outcome analysis in craniosynostosis surgery is difficult and often relies on limited anthropometric measurement, qualitative analysis of photography or patient reported outcome. Quantifiable morphable models of the human face have been described but, to date, a…
Date: March 2014 Source: PLOS Genetics. Abstract: Human facial diversity is substantial, complex, and largely scientifically unexplained. We used spatially dense quasi-landmarks to measure face shape in population samples with mixed West African and European ancestry from three locations (United States, Brazil, and Cape Verde). Using bootstrapped response-based imputation modeling (BRIM), we uncover the relationships…
Date: February 2014. Source: Surgical Innovation, 21(1):59-64. Background: Orthognathic surgery leads to alteration of the spatial relationship of the mandible and maxilla resulting changes in the degree of facial projection. Traditional 2-dimensional cephalometry and photographic techniques do not provide data on facial depth. Though stereophotogrammetry can be used as a noninvasive method for evaluating facial…
Date: 22 November 2013 Source: BBC News Article: Defining the most ‘normal’ shape of a human skull Reconstructive surgery for people born with a misshapen skull is one of medicine’s most complicated challenges. Part of the problem for surgeons is defining what a normal head actually looks like. A team of Liverpool-based surgeons, and artists,…
Date: Sep 2013 Source: International Journal of Oral and Maxillofacial Surgery, 42(9):1100-7. Abstract: The objective of this study was to compare the facial morphologies of an adult Chinese population to a Houstonian white population. Three-dimensional (3D) images were acquired via a commercially available stereophotogrammetric camera system, 3dMDface™. Using the system, 100 subjects from a Houstonian…

Visitors to London’s Science Museum are being invited to have their faces scanned in 3D. The ‘Me in 3D’ exhibit uses an array of cameras to build a virtual image visitors can then view and manipulate. Data from…
