What is it about?
This paper examines both the cephalic index and 3D changes in head shape that occur after extended sagittal strip craniectomy and postoperative helmet therapy.

Why is it important?
This work demonstrates the location and magnitude of head shape change after extended sagittal strip craniectomy for the treatment of sagittal craniosynostosis. The cephalic index normalized in less than 60 days showing that this is a dynamic process. Significant 3D changes were obtained in both vertical and horizontal dimensions of the posterior cranial vault from this passive technique that is driven by the growth of the brain. This data suggests that addressing both transverse and vertical deficiency of the posterior cranial vault should be considered when performing cranial vault surgery in patients with sagittal synostosis to better accommodate brain growth.
Perspectives
This paper demonstrates that significant 3D changes occur in the cranial vault after extended sagittal strip craniectomy with wedge ostectomies and helmet therapy. Cephalic index is a useful surrogate for head shape in patients with sagittal synostosis. However, our study demonstrates that significant changes occur in the vertical dimension of the cranial vault and the cephalic index does not incorporate objective measures of the vertical dimension. We favor 3D outcome measures in future studies to assess if normal proportions of the skull are achieved from cranial vault surgery.
