Bilateral traumatic abducens nerve palsy associated with skull base fracture--case report.
A 29-year-old man presented with skull base fractures involving the bilateral petrous bones and clivus to the posterior clinoid process manifesting as bilateral abducens nerves palsy. Conservative treatment resulted in residual bilateral abducens nerves palsy. Posterolateral impact probably resulted in strain-stress in the neighborhood of the foramen lacerum, resulting in a clivus fracture of the posterior clinoid process and bilateral petrous bone fractures. Chalasia of Gruber's ligament then exerted mechanical pressure on the bilateral abducens nerves.
