"Transsphenoidal basilar skull fractures are a particularly serious type of basilar skull fracture usually occurring in the setting of severe traumatic brain injury and with potential for serious complications including damaging the internal carotid arteries and optic nerves as well as high incidence of dural tear with CSF leak. Venous thrombosis complicates up to 31% of these fractures; as many as 75% of caroticocavernous fistulae will have antecedent skull base fractures."
