Which Le Fort fracture is a pyramidal fracture through the central maxilla and hard palate?

• A. Le Fort I fracture
• B. Le Fort II fracture
• C. Le Fort III fracture
• D. Zygomaticomaxillary fracture

Answer: (B)

A pyramidal fracture through the central maxilla and hard palate describes the midface injury pattern where fracture lines radiate from the nasal bridge downward through the maxilla, involving the inferior orbital rims and often the palate. This configuration creates a pyramid-shaped disruption that centers on the bone around the nose and upper jaw, distinguishing it from other Le Fort patterns. The horizontal break across the maxilla above the teeth defines a Le Fort I injury, which isolates the palate from the midface. A craniofacial disjunction through the orbital walls and zygomatic arches defines Le Fort III, a more extensive separation of the midface from the skull. A zygomaticomaxillary fracture is a separate pattern that involves the cheekbone and its buttresses but does not follow the Le Fort fracture lines.
