In a Le Fort II fracture, the fracture line passes through:

• A Across the hard palate separating teeth from the skull
• B Nasal bones, medial orbital wall, infraorbital rim and lateral maxillary wall (pyramidal) ✓
• C Zygomatic arch, lateral orbital wall, pterygoid plates and nasal bones (craniofacial dysjunction)
• D Anterior nasal spine only with palatal detachment

Explanation

Le Fort II (pyramidal) fracture separates the central midface as a pyramid. The fracture line traverses the nasal bones superiorly, runs through the medial orbital walls, crosses the infraorbital rims, passes through the lateral maxillary walls and pterygoid plates. The zygomatic arches remain attached. Le Fort I is a horizontal maxillary fracture. Le Fort III is craniofacial dysjunction where the entire midface separates from the skull, including the zygomatic arches.
