Primary Brain Injury Unique Fracture
A unique fracture is the basilar skull fracture.
It occurs at the base of the skull and results in CSF leakage from the nose or ears. Of significance with this fracture is the potential development of hemorrhage caused by damage to the internal carotid artery; damage to cranial nerves I, II, VII, and VIII; and infection.
The majority of penetrating injuries to the skull are caused by gunshot wounds and knife injuries. The degree of injury to the brain tissue depends on the velocity, mass, shape, and direction of impact.
