ENT · Nose and paranasal sinuses: nasoorbitoethmoid fracture

Sample item

After being struck on the nasal root by a bat, a man has a flattened nasal bridge, a widened distance between the inner angles of the eyes, and watering of the eye. What is the injury?

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

The answer and the reasoning

A. Nasoorbitoethmoid complex fracture

A nasoorbitoethmoid fracture drives the nasal bones back into the ethmoids and disrupts the medial canthal tendon attachment, giving traumatic telecanthus, a flat bridge and epiphora from lacrimal injury. It needs CT and open reduction.

Option by option

  • A. Nasoorbitoethmoid complex fracture (correct)

    Correct. A flat bridge, telecanthus and epiphora indicate a nasoorbitoethmoid fracture.

  • B. Orbital floor blowout fracture

    An orbital blowout gives diplopia on upgaze and enophthalmos, without telecanthus.

  • C. Isolated nasal bone fracture

    An isolated nasal fracture gives deviation and swelling without widening of the inner eye angles.

  • D. Zygomaticomaxillary complex fracture

    A zygomaticomaxillary fracture flattens the cheek and causes infraorbital numbness and trismus.
