Presurgical and postsurgical assessment of the neurodevelopment of infants with single-suture craniosynostosis: comparison with controls

Object Although most infants with single-suture craniosynostosis (SSC) appear to have neurodevelopmental test scores in the average range, SSC has been associated with cognitive and motor delays during infancy. Whether and when surgery improves such deficits are not yet known. The authors aimed to compare the pre- and postsurgical neurodevelopmental status of patients with SSC with those of control infants without craniosynostosis. Methods The authors conducted a large, multicenter, longitudinal study of 168 infants with craniosynostosis and 115 controls without synostosis who were of similar age, race, sex, and socioeconomic status. The authors assessed participants by using the Bayley Scales of Infant Development, Second Edition (BSID-II) and the Preschool Language Scale, Third Edition (PLS-3) at enrollment, before patients' intracranial surgery, and when participants were 18 months of age (after surgery for patients). Results After adjusting for potential confounding factors in linear regression analys...
