A<unk>  as seen on CT Diagram showing bones that may be involved in a<unk> <unk> s include breaks in the posterior<unk>  base or anterior<unk>  base. The former involve the occipital bone, temporal bone, and portions of the sphenoid bone; the latter, superior portions of the sphenoid and ethmoid bones. The temporal bone fracture is encountered in 75% of all<unk> s and may be longitudinal, transverse or mixed, depending on the course of the fracture line in relation to the longitudinal axis of the pyramid. Bones may be broken around the foramen magnum, the hole in the base of the<unk>  through which the brain stem exits and becomes the spinal cord. This may result in injury to the blood vessels and nerves exiting the foramen magnum. Due to the proximity of the cranial nerves, injury to those nerves may occur. This can cause loss of function of the facial nerve or oculomotor nerve, or hearing loss due to damage of cranial nerve VIII.
