Three-Dimensional Nasolabial Changes After Nasoalveolar Molding and Primary Lip/Nose Surgery in Infants With Bilateral Cleft Lip and Palate. L Mancini, S Avinoam, BH Grayson, RL Flores, DA Staffenberg, PR Shetye.

This is a retrospective serial longitudinal study of consecutively enrolled infants from September 2012 to July 2016 with BCLP who underwent NAM before primary lip and nose reconstructive surgery.

Automatic Assessment of 3-Dimensional Facial Soft Tissue Symmetry Before and After Orthognathic Surgery Using a Machine Learning Model. LJ Lo, CT Yang, CT Ho, CH Liao, HH Lin.

This study applied the transfer learning model with a convolutional neural network based on 3-dimensional (3D) contour line features to evaluate the facial symmetry before and after OGS. A total of 158 patients were recruited in a retrospective cohort study for the assessment and comparison of facial symmetry before and after OGS from January 2018 to March 2020. Three-dimensional facial photographs were captured by the 3dMD face system in a natural head position, with eyes looking forward, relaxed facial muscles, and habitual dental occlusion before and at least 6 months after surgery.

Evaluation of Changes in Nasal Projection After Surgically Assisted Rapid Maxillary Expansion With 3dMDface System. MH Büyükçavuş, Y Findik, T Baykul.

Date: April 2020. Source: The Journal of Craniofacial Surgery. DOI: 10.1097/scs.0000000000006436. Abstract: The most appropriate treatment option for maxillary expansion in adulthood due to increased cyanosis in sutures is surgically assisted maxillary expansion (SARME). Skeletal and dental changes are observed with SARME. Three-dimensional imaging techniques are gaining importance with the developing technology in evaluating the…

Patient- and 3D morphometry-based nose outcomes after skeletofacial reconstruction. R Denadai, PY Chou, HJ Seo et al.

Date: March 2020. Source: Scientific Reports, Volume 10, Article No. 4246, https://doi.org/10.1038/s41598-020-61233-6. Abstract: Patient satisfaction with the shape and appearance of their nose after orthognathic surgery-based skeletofacial reconstruction is an important, but often overlooked, outcome. We assessed the nose-related outcomes through a recently developed patient-reported outcome instrument and a widely adopted 3D computer-based objective outcome…

Nasal Alar Surface Area Differences After Unilateral Cleft Lip Repair. Long-Term Effects of the Perialar Incision. AT Perdanasari, RD Wagner, MJ Davis et al.

Date: March 2020 (Online). Source: Journal of Craniofacial Surgery, doi: 10.1097/SCS.0000000000006284. Background: The Millard rotation-advancement cleft lip repair is the most commonly performed cleft lip repair. An extended perialar incision allows for further advancement of the lateral lip element and improved positioning of the alar base. There is a lack of data evaluating differences in…

Assessing the Influence of Chin Asymmetry on Perceived Facial Esthetics With 3-Dimensional Images. T Dong, N Ye, L Yuan, S Wu, L Xia, B Fang.

Date: March 2020. Source: Journal of Oral and Maxillofacial Surgery. DOI: 10.1016/j.joms.2020.03.017. Objective: We used 3-dimensional (3D) images to assess the influence of chin asymmetry on perceived facial esthetics, investigate the cognitive boundaries of chin asymmetry among orthodontists, general dentists, and laypersons, and provide quantitative reference for clinical treatment. Materials and Methods: A 3D facial…

Three-dimensional facial volume analysis using algorithm-based personalized aesthetic templates. AJ Tuin, JW Meulstee, TGJ Loonen et al.

Date: February 2020 (Online). Source: International Journal of Oral and Maxillofacial Surgery. Abstract: Three-dimensional stereophotogrammetry is commonly used to assess volumetric changes after facial procedures. A lack of clear landmarks in aesthetic regions complicates the reproduction of selected areas in sequential images. A three-dimensional volumetric analysis was developed based on a personalized aesthetic template. The…

Long-term comparison study of philtral ridge morphology with two different techniques of philtral reconstruction. FC-S Chang, C-G Wallace, YC Hsiao et al.

Date: January 2020 (Online). Source: International Journal of Oral and Maxillofacial Surgery. Abstract: Cleft lip and/or cleft palate are the most common congenital craniofacial anomalies. Philtral ridge morphology is an important aesthetic component of unilateral cleft lip (UCL) repair. To this end, we have developed two techniques of philtral ridge reconstruction: (1) asymmetric mattress muscle…

Unilateral Cleft Lip Nasal Deformity: Three-Dimensional Analysis of the Primary Deformity and Longitudinal Changes following Primary Correction of the Nasal Foundation. R Tse, R Knight, M Oestreich et al.

Date: January 2020. Source: Plastic and Reconstructive Surgery: Volume 145, Issue 1, p 185-199 doi: 10.1097/PRS.0000000000006389. Background: Objective assessment of the unilateral cleft lip nasal deformity and the longitudinal changes with treatment is critical for optimizing cleft care. Methods: Consecutive patients undergoing cleft lip repair and foundation-based rhinoplasty were included (n = 102). Three-dimensional images…
