Abstract

Background

There is controversy regarding whether the frontal bossing associated with sagittal synostosis requires direct surgical correction or spontaneously remodels after isolated posterior cranial expansion. The authors retrospectively measured changes in frontal bone morphology in patients with isolated sagittal synostosis 2 years after open posterior and midvault cranial expansion and compared these changes with those occurring in age-comparable healthy control groups.

Methods

Forty-three patients age 1 year or younger (mean, 6 months) with sagittal synostosis underwent computed tomography scan digital analysis immediately after and 2 years after posterior–middle cranial vault expansion. Quantitative angular and linear measures were taken along the midsagittal and axial planes to capture both aspects of frontal bossing. The change in values over the 2 years were compared with healthy controls with normal computed tomography scans taken to rule out head trauma.
