craniosynostosis
Pronunciation: kray-nee-oh-sin-os-TOH-sis
Premature fusion of skull sutures leading to abnormal head shape and potential increased intracranial pressure.
Full Definition
Craniosynostosis involves the early closure of one or more cranial sutures, preventing normal skull growth and potentially causing increased intracranial pressure. The condition may be isolated or part of a genetic syndrome, requiring multidisciplinary care including neurosurgery, plastic surgery, and genetics. Different types are named for the affected suture (sagittal, coronal, metopic, lambdoid). This diagnosis appears in neurosurgical consultations, genetic evaluations, and craniofacial surgery reports. Accurate spelling and subtype identification are crucial for medical documentation.
Usage
Usage note: Note the complex spelling with 'synostosis'. Distinguish from positional plagiocephaly, which doesn't involve suture fusion.
