Eductional Objective: Direct trauma to the orbit could lead to orbital floor fracture. Crossing the orbital floor, the infraorbital nerve passes in a tunnel in the maxilla right before exiting the skull inferior to the orbit. Infraorbital injury leads to a sensory deficit in the upper gingiva, the upper lip, and the upper cheek. Additionally, vertical gaze palsy may occur due to inferior rectus muscle entrapment.
