Radiology · Neuroimaging: Le Fort II fracture

Sample item

A face injury causes a mobile midface with a pyramid-shaped fracture line that passes through the nasal bridge, medial orbital wall, infraorbital rim and the pterygoid plates. Which fracture is this?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Le Fort II

Le Fort II is the pyramidal fracture through the nasofrontal region, medial orbit, infraorbital margin and pterygoid plates, which leaves the maxilla and nose mobile. Le Fort I is a horizontal fracture above the teeth, and Le Fort III is craniofacial disjunction through the zygomatic arch and lateral orbit. A zygomaticomaxillary complex fracture involves the cheek.

Option by option

  • A. Zygomaticomaxillary complex fracture

    A zygomaticomaxillary complex fracture does not mobilise the nasal bridge.

  • B. Le Fort II (correct)

    Correct. A pyramidal fracture is the Le Fort II pattern.

  • C. Le Fort I

    Le Fort I is a horizontal fracture just above the teeth, separating the hard palate.

  • D. Le Fort III

    Le Fort III separates the face from the skull through the zygomatic arch and lateral orbit.
