fontanelle
Pronunciation: FON-tan-el
Soft spot on an infant's skull where cranial bones have not yet fused, examined to assess intracranial pressure and development.
Full Definition
A fontanelle is a membranous area between the cranial bones of an infant's skull where ossification is incomplete. The anterior fontanelle typically closes between 12-18 months, while the posterior fontanelle closes by 2-4 months. Clinical examination of fontanelles provides important information about hydration status, intracranial pressure, and normal development. A bulging fontanelle may indicate increased intracranial pressure, while a sunken fontanelle can suggest dehydration.
Usage
Usage note: The spelling 'fontanelle' (with double 'l') is preferred in medical documentation over 'fontanel'.
