Comparison of an unsupervised machine learning algorithm and surgeon diagnosis in the clinical differentiation of metopic craniosynostosis and benign metopic ridge. MJ Cho, RR Hallac, M Effendi, JR Seaward, AA Kane.

Date: April 2018. Source: Scientific Reports, Volume 8, Article number: 6312. Abstract: Metopic suture closure can manifest as a benign metopic ridge (BMR), a variant of normal, to “true” metopic craniosynostosis (MCS), which is associated with severe trigonocephaly. Currently, there is no gold standard for how much associated orbitofrontal dysmorphology should trigger surgical intervention. In…

Genetics of the human face: Identification of large-effect single gene variants. DJM Crouch, B Winney, WP Koppen, WJ Christmas, K Hutnik, T Day, D Meena, A Boumertit, P Hysi, A Nessa, TD Spector, J Kittler, WF Bodmer.

Date: January 2018. Source: People of the British Isles, Newsletter Issue 7. Abstract: We have been studying the genetics underlying human facial features since the renewal of our PoBI grant from the Wellcome Trust in 2009. We have been doing this by going back to as many of the original volunteers as we could to…

3D Assessment of Nasolabial Appearance in Patients With Complete Unilateral Cleft Lip and Palate. I Bagante, I Zepa, I Akota.

Date: December 2017. Source: The Cleft Palate-Craniofacial Journal. Objective: Rhinoplasty in patients with complete unilateral cleft lip and palate (UCLP) is challenging, and the surgical outcome of the nose is complicated to evaluate. The aim of this study was to assess the nasolabial appearance of patients with UCLP compared with a control group. Design: Cross-sectional…

A three-dimensional method for evaluating changes in lip morphology following correction of functional anterior crossbite. C Jogaki, W Tome, F Kuroyanagi, N Kitai.

Date: December 2017. Source: Orthodontic Waves, Volume 76, Issue 4, Pages 226-231. Purpose: The purpose of the present study was to present a three-dimensional method for evaluating changes in lip morphology and to apply the method to the therapy evaluation following the correction of functional anterior crossbite. Materials and Methods: Twenty-five Japanese patients (age: 6…

Depth accuracy of the RealSense F200: Low-cost 4D facial imaging. TC ten Harkel, CM Speksnijder, F van der Heijden, CHG Beurskens, KJAO Ingels, TJJ Maal.

Date: November 2017 Source: nature.com / Scientific Reports Abstract: The RealSense F200 represents a new generation of economically viable 4-dimensional imaging (4D) systems for home use. However, its 3D geometric (depth) accuracy has not been clinically tested. Therefore, this study determined the depth accuracy of the RealSense, in a cohort of patients with a unilateral…

Genetics of the human face: Identification of large-effect single gene variants. DJM Crouch, B Winney, WP Koppen, WJ Christmas, K Hutnik, T Day, D Meena, A Boumertit, P Hysi, A Nessa, TD Spector, J Kittler, WF Bodmer.

Date: October 2017 Source: PNAS | Proceedings of the National Academy of Sciences of the United States of America, doi: 10.1073/pnas.1708207114. Significance: The human face is extraordinarily variable, and the extreme similarity of the faces of identical twins indicates that most of this variability is genetically determined. We have devised an approach to increase the…

An eFTD-VP framework for efficiently generating patient-specific anatomically detailed facial soft tissue FE mesh for craniomaxillofacial surgery simulation. X Zhang, D Kim, S Shen, et al.

Date: October 2017. Source: Biomechanics and Modeling in Mechanobiology, pp 1–16, https://doi.org/10.1007/s10237-017-0967-6. Abstract: Accurate surgical planning and prediction of craniomaxillofacial surgery outcome requires simulation of soft tissue changes following osteotomy. This can only be achieved by using an anatomically detailed facial soft tissue model. The current state-of-the-art of model generation is not appropriate to clinical…

Analysis Methods of the Variation of Facial Size and Shape Based on 3d Face Scan Images. W. Lee, L Goto, J.F.M. Molenbroek, R.H.M. Goossens.

Date: October 2017. Source: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. Volume: 61 issue: 1, page(s): 1409-1413. Abstract: 3D scan images have been successfully applied in ergonomic product design. Features of human body parts (e.g., landmarks, measurements, curvatures, surfaces, volumes) extracted from 3D body scan images can be used to analyze variations…

A clinical technique for virtual articulator mounting with natural head position by using calibrated stereophotogrammetry. WYH Lam, RTC Hsung, WWS Choi, et al.

Date: September 2017. Source: The Journal of Prosthetic Dentistry (Online). Abstract: Accurate articulator-mounted casts are essential for occlusion analysis and for fabrication of dental prostheses. Although the axis orbital plane has been commonly used as the reference horizontal plane, some clinicians prefer to register the horizontal plane with a spirit level when the patient is…

Long-term Outcomes of Subtotal Septal Reconstruction in Rhinoplasty. SA Asher, AS Kakodkar, DM Toriumi.

Date: September 2017 Source: JAMA Facial Plastic Surgery. Importance: Significant nasal septal deviation may require complex reconstruction to achieve complete correction. Subtotal septal reconstruction is a method for addressing deviations in the L-strut. Objective: To review the long-term outcomes of subtotal septal reconstruction and provide objective evidence of functional and aesthetic improvement. Design, Setting, and…
