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. 


RADIOGRAPHIC FEATURES 


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"
