CSF Leak: Fractures of the floor of the middle cranial fossa may result in CSF leakage from the external acoustic meats (CSF otorrhea) if the meninges superior to the middle ear are torn and the tympanic membrane is ruptured. Fractures of the floor of the anterior cranial fossa may involve the cribiform plate resulting in CSF leakage through the nose (CSF rhinorrhea). Patient with these types of lesions have an increased risk of meningitis because an infection could spread to the meninges through the ear or nose.
