Abstract

Competing concepts exist regarding surgery for instance of the cleft lip and palate to date. In order to support the surgeon to predict the possible outcome of a variety of the approaches a promising procedure are morphology-based finite element simulations at histological scale. It however can be a challenge to generate volume meshes that are applicable to the mathematical modeling of three-dimensional spatial modifications. In this study we discuss the variation of the segmentations by different anatomy experts with respect to shape, analyze the associated reconstructions by the finite element method and compare them among one another. The gist of the study is that an exact segmentation is fundamental precedent for a simulation and minor deviations in shape may arise deviations in a finite element simulation.
