Anatomic Maps May Offer New Technique for Calculating Spine Curvature. Hospital for Special Surgery (HSS)

HSS researchers evaluating ‘3dMD’ technology to reduce x-ray use and improve therapy for scoliosis patients Researchers at Hospital for Special Surgery (HSS) in New York City are enrolling patients in a study using cutting-edge imaging technology to produce three-dimensional maps of the spine in people with scoliosis.

Effect of maxillary expansion and protraction on the oropharyngeal airway in individuals with non-syndromic cleft palate with or without cleft lip. N Alrejaye, J Gao, D Hatcher, S Oberoi.

Date: July 2019. Source: PLOS ONE. https://doi.org/10.1371/journal.pone.0213328. Introduction: The aim of this study was to evaluate three dimensionally the effect of the combined maxillary expansion and protraction treatment on oropharyngeal airway in children with non-syndromic cleft palate with or without cleft lip (CP/L). Methods: CBCT data of 18 preadolescent individuals (ages, 8.4 ± 1.7 years)…

Facial Gender Affirmation Surgery. DE Morris, LP Zhao.

Date: July 2019. Source: Journal of Craniofacial Surgery, Volume 30, Issue 5, p 1403–1405. Abstract: Facial procedures directed at gender affirmation are uniquely tailored to the individual patient and may affect soft tissue and skeletal structures over the entire face—from the chin through the upper forehead. Complete photographic and radiographic documentation that addresses these areas…

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…

Hemimandibular Hyperplasia Correction by Simultaneous Orthognathic Surgery and Condylectomy Under Digital Guidance. Bi Han, X Wang, Z Li et al.

Date: July 2018. Source: Journal of Oral and Maxillofacial Surgery, Volume 76, Issue 7, pp 1563.e1-1563.e18. Objective: Orthognathic surgery with simultaneous condylectomy under digital guidance has been proved to be a feasible method to treat hemimandibular hyperplasia (HH). The objective of this study was to evaluate the effects and precision of correction of HH by…

Three‐dimensional facial phenotyping in obstructive sleep apnoea. RWW Lee.

Date: June 2018 Source: Respirology, Volume 23, Issue 6, pp 560-561. Abstract: Craniofacial structure is an important anatomical determinant of obstructive sleep apnoea (OSA). While obesity is the major attributing risk factor for OSA, it is well established that a restricted craniofacial bony skeleton also contributes to a more collapsible upper airway, which is a…

Evaluation of facial asymmetry in patients with juvenile idiopathic arthritis: Correlation between hard tissue and soft tissue landmarks. S Economou, P Stoustrup, KD Kristensen, M Dalstra, A Küseler, T Herlin, TK Pedersen.

Date: May 2018. Source: American Journal of Orthodontics and Dentofacial Orthopedics, Volume 153, Issue 5, Pages 662–672. Hightlights: • Soft-tissue and hard-tissue asymmetries in JIA patients are correlated. • In JIA patients, asymmetries are most pronounced in the lower facial third. • Glabella had the least deviation. • Pogonion presented the largest level of deviation.…

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…

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…

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…
