Implementation of 3D Cellular Photogrammetry to Model and Attach Custom Ear Molds in Pediatric Craniofacial Anomalies

Children with craniofacial abnormalities (CFA) face social and clinical challenges ranging from social exclusion to limited access to affordable and effective treatment options. Current clinical solutions for this problem are costly, uncomfortable, and invasive, making it less accessible to many families. Patients that exhibit abnormalities of high-impact cases are sent to be scanned with expensive machinery which are used to create necessary prosthesis or molds. Technologically, there is a need for precise yet affordable scanners and biocompatible materials to create effective solutions. Studies have demonstrated the potential of 3D photogrammetry using monoscope imaging to create accurate and accessible facial prostheses emphasizing a pathway to more inclusive care. Advancements in LiDAR technology for 3D scanning have reduced the reliance on expensive clinical equipment and machinery, allowing for model scanning to be more accessible through mobile applications. This project builds on this by combining cellular photogrammetry scanning with patient-specific and non-invasive facial molds made from biocompatible materials while aiming to reduce disparities and improve the quality of life for pediatric patients. Therefore, the intellectual merit of the proposed project lies in integrating 3D cellular photogrammetry, 3D printing (3DP), biocompatible materials, and attachment systems to create an affordable and patient-specific mold.
