Fig. 5E. —Le Fort I fracture. To classify this Le Fort fracture, look at the following four facial segments: pterygoid processes (fractured in this case: Le Fort fracture is most likely present), anterolateral margins of nasal fossa above maxillary alveolar ridge (fractured: Le Fort I is likely present), inferior orbital rims (intact: Le Fort II is excluded), and zygomatic arches (intact: Le Fort III is excluded). Le Fort I fracture is confirmed by noting other expected fractures in plane of Le Fort I fracture. Three-dimensional image in frontal projection shows intact inferior orbital rims (black arrows), thus excluding Le Fort II fracture. Horizontally oriented fractures across maxillary sinuses and nasal fossa (white arrows) are seen.
