Developmental outcomes of preschool children requiring craniosynostosis surgery in Manitoba: a cohort study

Abstract

Abstract Craniosynostosis is a congenital abnormality resulting in the premature fusion of one or more cranial sutures and usually requires surgical correction in the first year of life. While the majority of craniosynostosis cases represent isolated, nonsyndromic defects, approximately 25% are linked to a genetic diagnosis. Craniosynostosis has been associated with developmental delay. Therefore, historically in Manitoba, all children with surgically managed craniosynostosis were referred to the Child Development Clinic (CDC) for developmental assessment. There are currently prolonged wait times for neurodevelopmental assessments at CDC, leading to the need to better prioritize children who require neurodevelopmental assessment. The aim of the study was then to determine the developmental outcomes of preschool children requiring craniosynostosis surgery in Manitoba from July 1, 2016 through December 1, 2021. In this retrospective cohort study, clinical records were reviewed to evaluate the developmental outcomes of patients who were assessed at CDC for surgically managed craniosynostosis. Out of 67 children included in this study, 18% demonstrated global developmental delay, 24% demonstrated mild developmental delay, and 58% were developmentally appropriate across all levels. The presence of a genetic syndrome, multisutural craniosynostosis, and parental socioeconomic status were associated with risk of global developmental delay. The findings of this study suggest that while not all children with craniosynostosis present with developmental delay, those with suspected or confirmed syndromic involvement, multisutural cranyosinostosis, and/or low SES, should be referred for neurodevelopmental evaluation.
