Statistical Shape Analyses of Patients with Scaphocephaly After Surgical Remodeling

Turk Neurosurg. 2020;30(3):382-386. doi: 10.5137/1019-5149.JTN.26387-19.2.

Abstract

Aim: To investigate the differences in the head shapes of scaphocephaly patients during the pre- and postoperative phases.

Material and methods: Cranium shape data were collected from the two-dimensional digital images. The generalised Procrustes analysis was used to obtain mean shapes in the pre- and postoperative phases. The shape deformation of the cranium from the pre- to postoperative phases was evaluated using the thin plate spline method.

Results: There was no significant cranial shape difference in the pre and postoperative phases. The high-level deformations from the pre- to postoperative phase were seen in thin plate spline graphs. The highest deformation was observed at the biparietal dimension.

Conclusion: In this study, we showed that the structural deformation of the cranium was correlated with sagittal craniosynostosis. The present study also shows that pre- and postoperative head shapes of patients with scaphocephaly can be compared using head shape with the landmark-based geometric morphometric method by taking into consideration the topographic distribution.
