SHAPE reads in a patient’s 3D photogram, automatically places a set of craniofacial landmarks, allows for their manual confirmation and correction, and automatically computes both a series of standard clinical craniofacial measurements and machine learning-based metrics of head development prior to building an analysis report for upload to the patient’s electronic medical record.

Photogrammetry is a useful tool to assess the aesthetic outcome after excision of skin tumors of the nose and reconstruction. AA Caretto, G Tarantino, C Grippaudo, E Candida, L Tagliaferri, K Peris, M Servillo, R Fortunato, R Bracaglia, S Gentileschi.

We enrolled 33 patients, comprising 24 men and 9 women, who were affected by cutaneous neoplasm on the nose and underwent excision followed by reconstruction with a flap. For each patient, we performed facial scans before and after surgery.

In summary, this study will serve as evidence to guide clinicians in deciding whether to perform the T&A on patients prior to functional therapy based on a wide range of objectively and subjectively measured outcomes and provide a reference for multidisciplinary management of OSA with craniofacial alterations in growing children.

Network analysis of three-dimensional hard-soft tissue relationships in the lower 1/3 of the face: Skeletal Class I-normodivergent malocclusion versus Class II-hyperdivergent malocclusion. T Wang, K Nie, Y Fan, G Chen, K Xu, G Song, B Han, Y Pei, T Xu.

The aim of this study was to clarify the hard-soft tissue relationships of the lower 1/3 of the face in skeletal Class II-hyperdivergent patients compared with those in Class I-normodivergent patients using network analysis.

A deep learning-based approach for automated landmark extraction from 3dMD facial photographs was developed and its precision was evaluated. The results showed high precision and consistency in landmark annotation, comparable to manual and semi-automatic annotation methods.

Impact of autologous breast reconstruction on bra fit. YT Liu, NH Khan, MC Bordes, et al.

Preoperative baseline breast measurements, age, and BMI can impact bra designs for breast cancer survivors who undergo autologous reconstruction due to size, shape, and symmetry changes. Bra needs of people who undergo autologous reconstruction differ from those who undergo implant-based reconstruction.

Automated three-dimensional analysis of facial asymmetry in patients with syndromic coronal synostosis: A retrospective study. TM Choi, X Liu, T Abdel-Alim, ML van Veelen, IMJ Mathijssen, EB Wolvius, GV Roshchupkin.

101 patients from 2005 to 2022 were selected for inclusion according to the following criteria: diagnosis molecularly confirmed; were of Caucasian descent; had only premature fusion of left and/or right coronal suture(s); had undergone only one craniofacial surgery; were younger than 18 years; had undergone no orthodontic treatment; had no extraction of permanent teeth; and had not undergone maxillary osteotomy.

Geometric learning and statistical modeling for surgical outcomes evaluation in craniosynostosis using 3D photogrammetry. C Elkhill, J Liu, MG Linguraru, S LeBeau, D Khechoyan, B French, AR Porras.

3dMD Customer Research, Computer Science | Computer Vision, Medical, 3dMDhead, Craniofacial/Cleft, Plastics

We present a fully automated pipeline to identify craniofacial landmarks in real time, and we use it to assess the head shape of patients with craniosynostosis using 3D photogrammetry.
