Both the Observer’s Expertise and the Subject’s Facial Symmetry Can Affect Anatomical Position of the Head. PH Sutton, J Gateno, JD English, J Paranilam, JF Teichgraeber, JJ Xia.

Date: October 2018. Source: Journal of Oral and Maxillofacial Surgery. Purpose: It is easier for us to judge facial deformity when the patient’s head is in anatomic position. The purposes of this study were to determine: 1) if a group of expert observers agree more than a group of non-experts on what is the correct…

Esthetic evaluation of facial cheek volume: A study using 3D stereophotogrammetry, J Feng, HY Yu, YJ Yin, YQ Yan, Z Wang, D Bai, XL Han.

Date: October 2018. Source: The Angle Orthodontist. Objective: To investigate the influence of cheek volume on facial esthetics judged by orthodontists and non-specialists. Materials and Methods: A 25-year-old female’s natural and smiling face was captured by 3D stereophotogrammetry. Cheek volume of the 3dMD image was altered to different degrees three-dimensionally. For the natural and smiling…

Regression of cephalic index following endoscopic repair of sagittal synostosis. NA Pickersgill, GB Skolnick, SD Naidoo, MD Smyth, KB Patel.

Date: October 2018. Source: Journal of Neurosurgery: Pediatrics [Online Before Print]. Objective: Metrics used to quantify preoperative severity and postoperative outcomes for patients with sagittal synostosis include cephalic index (CI), the well-known standard, and the recently described adjusted cephalic index (aCI), which accounts for altered euryon location. This study tracks the time course of these…

Applications and limitations of using patient-specific 3D printed molds in autologous breast reconstruction. S Hummelink, AC Verhulst, TJJ Maal, DJO Ulrich.

Date: October 2018. Source: European Journal of Plastic Surgery, Volume 41, Issue 5, pp 571–576. Background: Over the last years, several techniques have been proposed to improve the outcome of autologous breast reconstruction procedures. One of these innovations describes patient-specific, three-dimensional (3D) printed breast molds for intraoperative use based on 3D stereophotogrammetry. In this article,…

Reconstruction of the oral commissure in patients with unilateral transverse facial cleft. M Tuersunjiang, X Long, Y Fu, J Ke, H He, J Li.

Date: September 2018. Source: British Journal of Oral and Maxillofacial Surgery, Volume 56, Issue 7, pp 621-625. Abstract: The normal commissure is not a simple joint of the upper and lower lip, but a triangular mucosal area. To reconstruct a symmetrical oral commissure in patients with a unilateral transverse facial cleft, we designed composite vermilion…

A scale space approach for exploring structure in spherical data. V Vuollo, L Holmström.

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.…

Development of three-dimensional facial expression models using morphing methods for fabricating facial prostheses. A Matsuoka, F Yoshioka, S Ozawa, J Takebe.

Date: September 2018. Source: Journal of Prosthodontic Research. Purpose: It is essential to fabricate a best-fit three-dimensional (3D) facial prosthesis model capable of facial expressions. In order for the facial prosthesis to remain in position, especially around marginal areas subject to movement, a new method of making 3D facial expression models using time-series data allowing…

Non-radiographic severity measurement of pectus excavatum. DP Bliss Jr, NA Vaughan, RM Walk, JA Naiditch, AA Kane, RR Hallac.

Date: September 2018 [Online Before Print]. Source: Journal of Surgical Research, Volume 233, pp 376-380. Background: o avoid the radiation exposure of CT imaging and the expense of CT or MRI studies, we sought to develop a non-radiographic severity measurement of pectus excavatum based on 3D photogrammetric imaging. Methods: Over 28 mo, ten consecutive patient…

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…
