  • I. The fracture extends across the upper jaw (maxilla).

  • II. The fracture extends from the lower part of one cheek, up to and across the bridge of the nose, and then down to the lower part of the other cheek.

  • III. The fracture extends across the bridge of the nose and the bones surrounding the eyes.
