Date: May 2015. Source: Journal of Plastic, Reconstructive & Aesthetic Surgery, Volume 68, Issue 5, Pages 622–631. Background: The advent of three-dimensional stereo-photogrammetry in recent years has vastly helped the craniomaxillofacial field improve in terms of preoperative and intraoperative decision making. With regard to the auricle though, there is paucity of research as to the…

Date: April 2015 (online). Source: The European Journal of Orthodontics. Background/Objective: Judgement of nasolabial aesthetics in cleft lip and palate (CLP) is a vital component of assessment of treatment outcome. It is usually performed based on two-dimensional (2D) facial photographs. An increasing use of three-dimensional (3D) imaging warrants an assessment if 3D images can substitute…

Posterior cranial vault distraction in the management of syndromic multi-suture craniosynostosis: Outcomes and 3D photographic/CT-based morphometric analysis. CR Forrest, BM French, A Clausen.

Date: April 11-14, 2015. Source: AAPS 94th Annual Meeting, Scottsdale, AZ, USA. PURPOSE: Posterior cranial vault distraction has recently been popularized as a first intervention technique in the management of syndromic and multi-suture craniosynostosis. The purpose of this study was to present our experience with posterior cranial vault distraction in the management of these complex…

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,…
