What is Le Fort 2 osteotomy?
The Le Fort II osteotomy is a procedure that can simultaneously correct nasal and occlusal deformities, leading to improvements in a patient’s oral function and facial aesthetics. Despite its potential to correct nasomaxillary deformities, this procedure is rarely performed.
What bones are included in a Le Fort III fracture?
Le Fort Type III Also called cranial-facial separation, the fracture line in this injury passes from the nasofrontal area across the medial, posterior, and lateral orbital walls, the zygomatic arch, and through the upper portion of pterygoid plates.
What is a Le Fort III 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?
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.
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.
How many Le Fort fractures are there?
There are three types of Le Fort fractures that can be classified according to the specific plane of injury. In a Le Fort type I, the plane of injury is horizontal and typically results in a separation of the teeth from the upper face.
How is Le Fort fracture treated?
Treatment of a Le Fort fracture usually requires prompt stabilization of the fracture followed by surgery, in order to restore the typical facial orientation, re-establish proper positioning of the teeth, restore involved sinus cavities, and reunify the nose and eye socket.
How do you test for Le Fort fracture?
Mobility of the midface may be tested by grasping the anterior alveolar arch and pulling forward while stabilizing the patient with the other hand. The level of a Le Fort fracture (ie, I, II, III) can often be determined by noting the structures of the midface that move in conjunction with the anterior maxilla.
How is Le Fort fracture 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.
