Correct answer: EHorizontal fracture above the apices of the maxillary teeth, through the lateral nasal wall, lateral maxillary sinus wall, and pterygoid plates

Le Fort I is a horizontal fracture separating the lower maxilla (tooth-bearing segment) from the upper facial skeleton. The fracture line passes above the apices of the maxillary teeth, through the lateral nasal wall, lateral maxillary sinus wall, and pterygoid plates of the sphenoid bone bilaterally. It presents as a mobile maxillary alveolus ('floating palate'), facial swelling, and malocclusion. Le Fort II is the pyramidal fracture. Le Fort III is craniofacial dysjunction.
