What is a LeFort 1 fracture?
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.
How do you code a LeFort fracture?
ICD-10-CM Code for LeFort I fracture S02. 411.
What is the difference between LeFort 1 2 and 3?
Le Fort I is a floating palate (horizontal) Le Fort II is a floating maxilla (pyramidal) Le Fort III is a floating face (transverse)
What is Le Fort II fracture?
Le Fort Type II These fractures extend superiorly in the midface to include the nasal bridge, maxilla, lacrimal bones, orbital floor, and rim. They are pyramidal fractures with teeth at the base and nasal bone at the apex. These fractures are typically bilateral.
What bones are included in a Le Fort 1 fracture?
Bones fractured in a Le Fort I fracture include the lower nasal septum, the inferior portion of the pyriform apertures, the canine fossae, both zygomaticomaxillary buttresses, the posterior maxillary walls, and the pterygoid plates.
What does Le Fort mean?
Medical Definition of LeFort 1 : a fracture of the maxilla and associated bones of the midface region: a or LeFort I : a horizontal fracture of the maxilla above the apices of the teeth. b or LeFort II : a pyramid-shaped fracture of the maxilla in which the lines of fracture meet at an apex near the bridge of the nose.
What is Le Fort classification?
The classification of Le Fort fractures is based on the plane of injury: type I is a horizontal injury, type II is a pyramidal injury, and type III is a very extensive transverse injury that often results in a craniofacial dislocation.

What is 3 piece Le Fort 1 osteotomy?
The LeFort I osteotomy is one of the most commonly used procedures to correct midface deformities. It allows for correction in three dimensions including advancement, retrusion, elongation, and shortening.
What is the Le Fort classification?
What is a La Forte?
A Le Fort fracture of the skull is a classic transfacial fracture of the midface, involving the maxillary bone and surrounding structures in either a horizontal, pyramidal or transverse direction.
How is Le Fort diagnosed?
Practical points
- fracture of the pterygoid plates is mandatory to diagnose Le Fort fractures.
- anterolateral margin of the nasal fossa involvement.
- inferior orbital rim involvement.
- zygomatic arch involvement.
- nasofrontal suture involvement indicates either a type II or III fracture.
What is a Le Fort 3 fracture?
Le Fort III fracture (transverse), otherwise known as craniofacial dissociation, may follow impact to the nasal bridge or upper maxilla. The salient feature of these fractures, beyond pterygoid plate involvement, is that they invariably involve the zygomatic arch, or cheek bone.
What is 3 piece LeFort 1 osteotomy?
How is a LeFort 1 done?
During the LeFort I surgery, the upper jaw (or maxilla) is separated from the rest of the face and repositioned. This repositioning of the bones of the face is also called orthognathic surgery. Once separated, the upper jaw can be moved up, down, forward, backward, tilted, or turned.
What is 3 piece LeFort?
LeFort 3 distraction is surgery to reposition the cheek bones, orbits and upper jaw. “Distraction” means the bones are moves slowly over several weeks, in order to achieve a larger movement and less relapse. LeFort 3 distraction can improve obstructive sleep apnea, and reduce exorbitism.

How long is LeFort surgery?
The length of surgery depends on upon the complexity of the case. Routine surgery on one jaw typically takes one to two hours. Surgery that involves multiple procedures may take as long as three to five hours.
How is LeFort 3?
LeFort 3 distraction is performed by making a zigzag incision on top of the head. This incision is hidden within the hair. There are also incisions inside the mouth. The bones are cut, and internal distraction devices are placed.
