OBJECTIVE Although syndromic craniosynostosis is one of the causes for early closure of the anterior fontanelle, there is no literature on the incidence and causes of fontanelle closure in isolated single-suture craniosynostosis. The objective of this study was to review the incidence of fontanelle closure by a wormian bone in isolated, nonsyndromic sagittal craniosynostosis. METHODS Intraoperative records of 100 consecutive children under 1 year of age, operated for isolated sagittal synostosis over a 14-year period (1987- 2000), were reviewed to identify the presence of a wormian bone closing the anterior fontanelle. RESULTS The median age at surgery was 4.2 months with a range of 1.9-11.7 months. Intraoperatively, a wormian bone was seen replacing the anterior fontanelle in 4 cases giving an incidence of 4%. CONCLUSIONS A wormian bone can occupy the anterior fontanelle in children with isolated sagittal craniosynostosis giving the appearance of a 'closed fontanelle'.

D003398 Craniosynostoses Premature closure of one or more CRANIAL SUTURES. It often results in plagiocephaly. Craniosynostoses that involve multiple sutures are sometimes associated with congenital syndromes such as ACROCEPHALOSYNDACTYLIA; and CRANIOFACIAL DYSOSTOSIS.
