Lambdoid craniosynostosis (LC) is a rare non-syndromic craniosynostosis characterized by fusion at birth of the lambdoid sutures at the back of the head. While surgical options such as spring-assisted cranioplasty are available, the aesthetic results are often suboptimal. To tackle this problem, a parametric Finite Element (FE) model of the LC skulls was developed to optimize future spring surgeries.
Skull geometries from three different LC patients who had undergone spring correction were reconstructed from pre-operative CT data in Simpleware software. Simulation was carried out to compare the skull growth between the pre-operative CT imaging and the surgery. By reproducing this procedure in a virtual setting, this approach may help to improve LC surgeries in future.
