    Schematic diagram of the course of the sixth cranial nerve from the pons (A) to the lateral rectus muscle (F) . The nerve ascends over the petrous bone (D) and under Gruber’s ligament (E) as it passes through Dorello’s canal (C) . The nerve is tethered by dura before and after the canal (stars) . Injury to the peripheral nerve is thought to occur by contusion against the petrous ridge after midfrontal head impact. B, Posterior clinoidal process; G, globe.
