The zygoma being divided,tlie malar bone is dislocated outward and upward, and the contentsof the orbit are raised, when the infra-orbital nerve may be followedback to the foramen rotundum, where the nerve is seized and pulledout. The third division of the trigeminal nerve leaves the skull by wayof the foramen ovale, and divides into anterior and posterior branches.The posterior branch is sensory and in turn divides into the auriculo-.
