Effect of alar base cinch suture based on anatomic landmarks on the morphology of nasolabial region in patients after orthognathic surgery. W Zhang W, XJ Liu, ZL Li, Y Zhang.

This modified alar base cinch suture is more favorable for the postoperative nasal coordination and nasolabial morphology in patients who need mild to moderate maxillary advancement, and it has certain advantages in operability and objective accuracy.

Multicenter comparison of head shape outcomes for three minimally invasive strip craniectomy techniques for sagittal craniosynostosis. I Rizvi, RR Hallac, EL Geisler, JK Perez, BY Ainuz, MP Pressler, SA Jackson, GB Skolnick, MD Smyth, JR Seaward, CA Derderian, LR David, CM Runyan, KB Patel, AA Kane.

Preoperative and final postoperative 3dMD stereo photogrammetric images from patients who met the inclusion criteria had been collected as part of routine clinical imaging protocols in place at each study site. This large, retrospective, multicenter study illustrated whole head shape outcomes from three different craniectomy procedures.

Handy: Towards a high fidelity 3D hand shape and appearance model. R Potamias, S Ploumpis, S Moschoglou, V Triantafyllou and S Zafeiriou.

We collected a large dataset comprising of textured 3D hand scans. Our hand data were captured during a special exhibition at the Science Museum, London. The capturing apparatus utilized for this task was a 3dMDhand5 system, which is an active stereo photogrammetry software-driven optics-based system, which produces high quality dense meshes.

Initial Steps towards a Multilevel Functional Principal Components Analysis Model of Dynamical Shape Changes. DJJ Farnell, P Claes.

Multilevel PCA (mPCA) has been used by us to analyze 3D facial shapes obtained from 3D facial scans; note that two-level multilevel PCA (mPCA) is equivalent to bgPCA. mPCA has been used previously to investigate changes by ethnicity and sex, facial shape changes in adolescents due to age, and the effects of maternal smoking and alcohol consumption on the facial shape of English adolescents.
