The foramen lacerum is an irregularly shaped bony opening in the Skull base in the region of the middle cranial fossa.
Anatomy
The Internal carotid artery lies over the foramen lacerum and gives its name to this segment of the internal carotid artery. The foramen lacerum itself is closed by fibrous and cartilage tissue, and no relevant structures pass through it[^1]. The foramen lacerum has the following bony dimensions[^1]:
Dimension | Right (mm) | Left (mm) | Range (mm) |
Length | 6,3 | 6,49 | 0,25 - 11,75 |
Width | 5,36 | 5,25 | 3,0 - 7,5 |
