The existence of multiple foramina in the base of the skull permits the passing of crucial vital tissues, most importantly, blood vessels and nerves which pass from the head to the body and vice versa. Foramen lacerum is an irregular opening located in the middle cranial fossa at the base of the skull. It is covered by cartilage after birth. It is formed by the apex of the petrous temporal bone and allows the passing of the internal carotid artery, the deep petrosal nerve which arises from the carotid plexus that surrounds the internal carotid artery, and greater petrosal nerve.[1]
