Dentistry · Oral and maxillofacial surgery and facial fractures: naso-orbito-ethmoid fracture

Sample item

After a blow to the nasal bridge, a patient has a flattened nose, widened distance between the inner canthi and rounded medial canthi. Pressing on the medial canthus shows the tendon is detached. Which fracture is this?

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

The answer and the reasoning

D. Naso-orbito-ethmoid fracture

In a naso-orbito-ethmoid fracture the medial canthal tendon is detached, producing telecanthus. It may also cause CSF leak and lacrimal injury.

Option by option

  • A. Le Fort II fracture

    Le Fort II involves a pyramidal midface fracture with mobile maxilla.

  • B. Orbital blowout fracture

    A blowout fracture gives enophthalmos and limited vertical gaze.

  • C. Isolated nasal bone fracture

    An isolated nasal fracture does not widen the intercanthal distance.

  • D. Naso-orbito-ethmoid fracture (correct)

    Correct. Telecanthus with a detached tendon identifies this injury.
