Developmental Outcomes for Children With Unoperated Metopic or Sagittal Craniosynostosis: Findings at 3 and 7 Years From the Craniofacial Collaboration UK.

ABSTRACT

The Craniofacial Collaboration UK (CC-UK) is a shared initiative with the aim of addressing key limitations in the existing literature and examining the development of homogenous samples of children with craniosynostosis. This article preliminarily describes developmental, behavioral, and cognitive outcomes for children with either metopic synostosis (MS) or sagittal synostosis (SS), who were unoperated and managed conservatively under the CC-UK protocol. A total of 112 patients were included, and assessments conducted at 3 and/or 7 years of age are presented. The majority of unoperated patients were assessed as having mild clinical severity. Findings are broadly consistent with previous work, indicating that the majority of unoperated patients perform within the average ranges across assessments. For unoperated MS patients, higher than expected rates of developmental concerns were seen at 3 years, particularly relating to gross and fine motor skills, and personal social skills. Slightly elevated rates of behavioral concerns relating to hyperactivity and prosocial behavior were also consistently shown. Few developmental issues were found for SS patients at 3 years. Some minor concerns with peer relationships and prosocial behavior at 3 years, and emotional problems at 7 years were shown, but these were inconsistent over time. Cognitive ability in both groups at 7 years seems to be close to average. Overall findings are positive, and future work should build on these findings by recruiting larger samples and examining longer-term outcomes in adolescence and adulthood, to better understand the developmental trajectory of patients with unoperated craniosynostosis.
