Fig. 3B. —Le Fort III fracture. (Reprinted with permission from
[2]) Drawings show plane of Le
Fort III fracture in lateral (A) and frontal (B) projections. Le
Fort III fracture separates bones of face from rest of skull. Pterygoid plates
are broken, as is true in all types of Le Fort fracture. Upper posterior
margins of maxillary sinuses fracture, as does zygomatic arch, lateral orbital
wall, and lateral orbital rim. There is fracture near junction of frontal bone
and greater wing of sphenoid in posterior aspect of orbit, fracture along
medial orbital wall, and fracture across nasofrontal suture. Maxillary teeth,
nose, and zygomata as a unit would be movable on physical examination relative
to rest of skull.
