In Le Fort fracture classification, which level of midface fracture passes through the pterygoid plates and causes a floating palate (separation of the entire hard palate and dental arch from the cranial base)?

• A Le Fort I
• B Le Fort II
• C Le Fort III
• D All Le Fort levels pass through the pterygoid plates ✓

Explanation

All three Le Fort fracture levels pass through the pterygoid plates posteriorly — this is a defining anatomical constant. Le Fort I (low-level transverse fracture) causes a floating palate separating the tooth-bearing maxillary segment. Le Fort II (pyramidal fracture) extends through the orbital floors and nasal bones. Le Fort III (craniofacial dysjunction) separates the entire midface from the cranial base through the zygomatic arches and orbital walls. The pterygoid plate involvement in all levels is a key NEET PG fact.
