Foramen caecum

The foramen caecum is located in the anterior cranial fossa, anterior to the cribriform plate of the ethmoid bone and posterior to the frontal bone, within the frontoethmoidal suture. It lies at a variable distance from the crista galli.

The foramen caecum is frequently found in infants, uncommonly in children, and rarely in adults where <1.5% of foramina are open. It rarely transmits emissary venous connections (intra- or extra-cranial) to the nasal cavity.
