UW QID# 11742 had the same question. Fracture of the orbital floor causes displacement of the orbital contents through the floor and can cause enophthalmos and entrapment of the IR muscle (diplopia when looking up). Also, damage to the infraorbital nerve (a branch of V2), which exits through the infraorbital foramen, will cause numbness of the upper cheek, upper lip, and upper gingiva.
