C. The fracture separates the mid-face from the skull, and involves the central maxilla and nasal bones.
D. Basilar skull fractures are not associated with type II.

Back 3

D. They are.

Front 4

(Trauma Atlas)
In regards to LeFort III fractures, which of the

following is incorrect?
A. Associated complications are common, including airway compromise.
B. AKA : "craniofacial dissociation"
C. The main bones involved are : zygomas, nasal bones, ethmoids, vomer and base of skull.

B. Bleeding and Airway compromise are the main immediate injury complications.

C. LeFort I is a horizontal fracture pattern involving the zygomatic bone.

D. Le Fort II is a pyramidal fracture pattern.

Back 5

C. Maxilla - Alveolar process + hard palate + nasal bone floor.

Front 6

List the bony components of the leFort II

fracture.

Back 6

1. Upper nasal bridge

2. Medial wall of orbits

3. Zygomatico-maxillary suture lines

Front 7

List the bony components of the LeFort III

Fracture.

Back 7

1. Upper nasal bridge

2. Horizontally through bilateral orbits

3. Through Fronto-Zygomatic sutures

4. Through Zygomatic arches

Front 8

What are 2 tests for CSF rhinorrhoea ?

Back 8

1. Halo test

2. Beta 2 Transferrin

[ Beta 2 transferrin not in blood, sweat ,tears or mucous]

Front 9

List the Differences in Emergent Airway

Management for Severe LeFort Fractures

( Especially III )

Back 9

1. Manually pulling forward mid-face

(First Aid for clearing airway )

2. Avoid Nasal instrumentation (No NPA)

3. Early Intubation = likely endoscopic

4. Pharyngeal packing + nasal packing for

ongoing bleeding
