The foramen lacerum (Latin for lacerated piercing) is a triangular hole in the base of the skull located between the sphenoid, apex of petrous temporal and basilar part of occipital.

Structure[edit]

The foramen lacerum is a foramen situated directly inferior to the opening of the carotid canal. [1]:776

Development[edit]

The foramen lacerum fills with cartilage after birth. [1]:776

Function[edit]

The internal carotid artery passes from the carotid canal in the base of the skull, emerging and coursing superior to foramen lacerum as it exits the carotid canal. The internal carotid artery does not travel through foramen lacerum. The segment of the internal carotid artery that travels above foramen lacerum is called the lacerum segment. The artery of pterygoid canal, the nerve of pterygoid canal and some venous drainage pass through the foramen lacerum.

Clinical relevance[edit]
