craniosynostosis
Pronunciation: kray-nee-oh-sin-oh-STOH-sis
Premature fusion of one or more cranial sutures, resulting in abnormal skull shape and potential increased intracranial pressure.
Full Definition
Craniosynostosis is a condition in which one or more of the fibrous joints (sutures) between the bones of an infant's skull close prematurely, before the brain has fully developed. This premature closure restricts normal skull growth and can lead to increased intracranial pressure, abnormal head shape, and potential developmental delays. Craniosynostosis can be isolated to a single suture or involve multiple sutures, and may occur as part of genetic syndromes. Treatment typically requires surgical intervention to release the fused sutures and allow normal brain growth.
Usage
Usage note: Specify which suture is involved when known; distinguish from positional plagiocephaly which does not involve suture fusion.
