Orbital volume and shape in Treacher Collins syndrome

This study investigates orbital phenotypes in TCS using cephalometry and orbital shape analysis.Eighteen TCS and 52 control patients were included in this study, using the Dr Warehouse database. Orbital cephalometry was based on 20 landmarks, 10 planes, 16 angles, and 22 distances. Orbits were segmented. Registration-based, age-specific mean models were generated using semi-automatic segmentation, and aligned and compared using color-coded distance maps – maximum absolute distance (MAD), Hausdorff distance (HD), and Dice similarly coefficient (DSC).
