Study Completion Date: June 2015
Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Behavioral: neurobehavioral development
    observational study of infant and child development
Detailed Description:
In the first phase of this multi-site, 10-year longitudinal study, infants with one of four types of single-suture craniosynostosis were recruited: sagittal, metopic, right unilateral coronal, and left unilateral coronal. A case-matched "control" group of healthy, normal infants was also followed. This study, which is now in its second phase, is following this same cohort of children at the age of 7 years.

Ages Eligible for Study:   2 Months to 7 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Children with single-suture craniosynostosis between the ages of 2 months and 3 years were recruited and followed during phase 1. This same chort of children are now being followed at the age of 7 (phase 2). See eligibility criteria section for more information.

Enrollment criteria at Phase 1:

  • Confirmed diagnosis of single-suture, nonsyndromic craniosynostosis (sagittal, metopic, unilateral coronal, or lambdoid)
  • Corrective (cranioplastic) surgery not yet performed
  • Child born at 34 weeks gestation or later
  • Absence of neurological conditions/significant health problems
  • 33 months or younger at time of enrollment (male or female).

Enrollment criteria at Phase 2:

All participants enrolled in phase 1 are invited to participate in phase 2.
