Fig. 2. Le Fort fractures. Le Fort I fractures are low, transverse maxillary fractures that do not involve the orbit. Le Fort II fractures involve the nasoethmoid and maxillary bones, with involvement of the inferior and medial orbital walls. Le Fort III fractures extend from the nasoethmoid region across the orbit, involving the orbital floor and the medial and lateral walls (producing craniofacial disjunction).
