Lefort classification is the historic classification which is widely used to classify mid facial fractures. The lefort classification was given by Rene Lefort ,who classified mid facial fracture into Lefort I , II and III. Lefort 2 fracture is referred as ‘ PYRAMIDAL or SUBZYGOMATIC FRACTURE .’ Lefort 2 is a floating maxilla which runs from the thin middle area of the nasal bones down either side , crossing the frontal processes of the maxilla into the medial wall of each orbit . Within the orbit , the fracture line runs across the lacrimal bone behind the lacrimal sac to cross the infra orbital margin medial to or through the infra orbital foramen . Extends downwards & backwards across the lateral wall of the antrum below the zygomaticomaxillary suture & divides the ptyergyoid laminae .Le fort fractures are blunt trauma facial fractures which involves specific pattern of facial bones injury. Pterygoid process of sphenoid bones is involved in all Le fort fractures. Lefort fractures are classified further depending upon the involvement of zygomatic, nasal and maxillary bones. Blunt facial traumas due to motor vehicle collision, assault, falls or sports injury are the most common causes. In our case, Le fort 2 fracture resulted from motor vehicle collision.
