Sample item

After a road accident a patient has bilateral periorbital bruising, infraorbital numbness, a step at the infraorbital rim and a mobile midface with a movable nose. What is the likely fracture?

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

The answer and the reasoning

C. Le Fort II

Le Fort II is a pyramidal fracture crossing the nasal bridge, medial orbit, infraorbital rim and maxilla to the pterygoid plates. Infraorbital nerve involvement causes cheek and upper lip numbness.

Option by option

  • A. Isolated nasoethmoid

    Nasoethmoid fractures do not make the whole midface mobile.

  • B. Le Fort I

    Le Fort I spares the orbit and nose.

  • C. Le Fort II (correct)

    Correct. The pyramidal fracture involves the infraorbital rim.

  • D. Isolated mandibular

    A mandibular fracture does not produce midface mobility.
