Answer

Congenital malformation of the stapedial footplate has been implicated in the development of meningitis. Head and neck surgery, penetrating head injury, comminuted skull fracture, and osteomyelitic erosion may infrequently result in direct implantation of bacteria into the meninges. Skull fractures can tear the dura and cause a CSF fistula, especially in the region of the frontal ethmoid sinuses. Patients with any of these conditions are at risk for bacterial meningitis.
