Date: September 2018. Source: Computational Statistics & Data Analysis, Volume 125, pp 57-69. Highlights: • A novel scale space technique for analyzing spherical data is proposed. • Distributions of normal vector directions computed from a 3dMDhead image are analyzed. • A movie is a convenient way to explore the maps included in a SphereSiZer atlas.…

Assessing calvarial vault constriction associated with helmet therapy in deformational plagiocephaly. EC Peterson, KB Patel, GB Skolnick, KD Pfeifauf, KN Davidson, MD Smyth, SD Naidoo.

Date: Aug 2018. Source: Journal of Neurosurgery: Pediatrics. Volume 22: Issue 2: pp 113-221. Objective: Deformational plagiocephaly and/or brachycephaly (DPB) is a cranial flattening frequently treated in pediatric craniofacial centers. The standard of care for DPB involves patient positioning or helmet therapy. Orthotic therapy successfully reduces cranial asymmetry, but there is concern over whether the…

Female Facial Attractiveness Assessed from Three-Dimensional Contour Lines by University Students. J Jirathamopas, YF Liao, EWC Ko, YR Chen, CS Huang.

Date: May 2018. Source: Dentistry Journal, Volume 6, Issue 2, 16. Background: Three-dimensional (3D) images could provide more accurate evaluation for facial attractiveness than two-dimensional (2D) images. The 3D facial image could be simplified into gray scale 3D contour lines. Whether female facial attractiveness could be perceived in these simplified 3D facial contour lines should…

Estimating age and synthesising growth in children and adolescents using 3D facial prototypes. H Matthews, A Penington, J Clement et al.

Date: May 2018. Source: Forensic Science International, Volume 286, pp 61-69. Highlights: • Describes a framework for age estimation and growth prediction from 3D photographs. • Accuracy of both approaches is assessed. • This work can facilitate person identification and building 3D facial composites. Abstract: 3D facial images are becoming increasingly common. They provide more…

Test-retest reliability of smile tasks using three-dimensional facial topography. C Tanikawa, K Takada.

Date: May 2018. Source: Angle Orthodontist, Vol 88, No 3, pp 319–328. Objective: To evaluate the test-retest reliability of three types of facial expression tasks using three-dimensional (3D) facial topography. Methods: Twelve adult volunteers were enrolled in this study. They were instructed to perform three different facial expression tasks: rest posture, posed smile, and maximum…

Patient-specific 3D Models Providing a 21st Century Approach to Reconstructive Surgery. H Liss, SG Maliha, L Witek et al.

Date: April 2018. Source: Society For Biomaterials 2018 Annual Conference and Exposition, Atlanta, GA, USA. Statement of Purpose: Through the implementation of 3D- printed models in the operating room, plastic surgeons are able to visualize and reconstruct key anatomical features for patients seeking an autogenous ear reconstruction or rhinoplasty. The 3D-printed constructs are sterilizable patient-specific,…

Three-dimensional photography for the evaluation of facial profiles in obstructive sleep apnoea. SW Lin, K Sutherland, YF Liao, PA Cistulli, LP Chuang, YT Chou, CH Chang, CS Lee, LF Li, NH Chen.

Date: February 2018. Source: Respirology, 10.1111/resp.13261. Background and Objective: Craniofacial structure is an important determinant of obstructive sleep apnoea (OSA) syndrome risk. Three-dimensional stereo-photogrammetry (3dMD) is a novel technique which allows quantification of the craniofacial profile. This study compares the facial images of OSA patients captured by 3dMD to three-dimensional computed tomography (3-D CT) and…

Facial morphology and growth following surgery for congenital midline cervical cleft patients. Y Fan, H Matthews, N Kilpatrick, P Claes, J Clement, A Penington.

Date: January 2018 (Online). Source: International Journal of Oral and Maxillofacial Surgery. Abstract: Congenital midline cervical cleft (CMCC) is a rare condition that consists of a cutaneous midline neck lesion with a sinus extending inferiorly towards the sternum. A fibrous band that extends superiorly to the mandible is a consistent feature of the condition. Restriction…

3D Modelling of Facial Skin Surface for 3D Printing. Emma Ekberg.

Date: December 2017. Source: Master’s Thesis 2017:EX056, CHALMERS UNIVERSITY OF TECHNOLOGY. Abstract:One of the major global health problems today is burns, with an estimate of 256000 deaths each year caused by fires [1]. For more severe burns the probability of infections increases and here the golden standard is to use autologous skin grafts. However, the…

Modelling of Orthogonal Craniofacial Profiles. H Dai, N Pears, C Duncan.

Date: November 2017. Source: Journal of Imaging 2017, 3(4), 55; doi:10.3390/jimaging3040055. Abstract: We present a fully-automatic image processing pipeline to build a set of 2D morphable models of three craniofacial profiles from orthogonal viewpoints, side view, front view and top view, using a set of 3D head surface images. Subjects in this dataset wear a…
