Fig. 7F. —Combined Le Fort I fracture on right and Le Fort II and III fractures on left. Look at four facial segments one side at a time. First, look at the right side: pterygoid process (fractured in this case: Le Fort fracture is most likely present), right anterolateral margin of nasal fossa above maxillary alveolar ridge (fractured: Le Fort I is likely present), inferior orbital rim on right (intact: Le Fort II is excluded), and zygomatic arch on right (intact: Le Fort III is excluded). Right-sided Le Fort I fracture is confirmed by noting other expected fractures in plane of Le Fort I fracture. Next, look at the left side: pterygoid process (fractured in this case: Le Fort fracture is most likely present), left anterolateral margin of nasal fossa above maxillary alveolar ridge (intact: Le Fort I is excluded), left inferior orbital rim (fractured: Le Fort II is likely present), and left zygomatic arch (fractured: Le Fort III is likely present). Left-sided Le Fort II and III fractures are confirmed by noting other expected fractures in planes of Le Fort II and III fractures. Axial CT image shows fracture of zygomatic arch on left (arrow) at zygomaticotemporal suture; Le Fort III is present on left.
