FRACTURA LEFORT 1 PDF

Images by RosarioVanTulpe - Own work. Le Fort I level fractures are essentially a separation of the hard palate from the upper maxilla due to a transverse fracture running through the maxilla and pterygoid plates at a level just above the floor of the nose. LeFort II fractures transect the nasal bones, medial-anterior orbital walls, orbital floor, inferior orbital rims and finally transversely fracture the posterior maxilla and pterygoid plates. LeFort III fractures result in craniofacial disjunction. This is the highest level LeFort fracture and essentially separates the maxilla from the skull base. The fracture is a transverse separation of the nasofrontal suture, medial orbital wall, lateral orbital wall or zygomaticofrontal suture, zygomatic arch and pterygoid plates.
