Le Fort Fractures (LFF) are fractures of the mid face.
They collectively involve separation of all or a portion of the mid
face from the skull base. The pterygoid plate of the sphenoid bone
needs to be involved as they connect to the mid face to the
sphenoid bone dorsally.
3 lines to aid evaluation in maxillofacial fractures on an occipitomental (OM) skull x-ray
1 . Orbital line traces the inner margins of the lateral,
inferior, and medial orbital walls, and the nasal arch
2. Zygomatic line traces the superior margin of the
zygomatic arch and body, extending along the frontal
process of the zygoma to the zygomaticofrontal suture
3. Maxillary line traces the inferior margin of the zygomatic
arch, body, and buttress, and the lateral wall of the
maxillary sinus. Lines 2 +3 form "Dolan's elephant"
