Le Foe II facial fracture implies -
Ans. is 'd' i.e., Similar to C but on both sides Le Fo Classification of Mid-face Le Fo I (transverse fracture)the line runs above & parallel to the palate and effectively separates the alveolus and palate from the facial skeleton above.it crosses the lower pa of the nasal septum, maxillary antra and the pterygoid plates.Le Fo II fractureit is pyramidal in shape and passes through the root of nose, lacrimal bone, floor of orbit, upper pa of maxillary sinus and pterygoid plates. the orbital floor is always involvedLe Fo III fracture (craniofacial dysjunction) there is complete separation of facial bones from the cranial bones.the line runs high through the nasal bridge, septum and ethmoids, and through the bones of orbit to the frontozygomatic suture. The zygomaticarch fractures and the facial skeleton is separated from the bones above at a high level through the lateral wall of maxillary sinus and the pterygoid plates.
Fracture running through alveolar ridge
Fracture running through midline of the palate and zygomatico maxillary suture
Fracture running through zygomatic process of the maxilla, floor of orbit, root of nose on one side only
Similar to C but on both sides
