What is a Le Fort 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.
What causes a Le Fort fracture?
Le Fort fractures are typically the result of forceful impact to the face. They are often caused by rapid deceleration car crashes in which the midface strikes a stationary object, such as the car’s dashboard. It can also occur if the midface is struck by a rigid object, such as a baseball bat.
How many types of LeFort fractures are there?
These fractures are classified into three distinct groups based on the direction of the fracture: horizontal, pyramidal or transverse.
What is a Le Fort 2 fracture?
Definition. The Le Fort II fracture is also referred to as a pyramidal fracture. It commonly extends from the pterygoid plate through the maxilla, through the nasal orbital ethmoid area, and nasofrontal bone. Patients with Le Fort II injuries are often admitted to hospital unconscious and intubated.
What is Le Fort procedure?
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 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)
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 do you remember Le Fort fractures?
A memory aid is:
- 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 a Le Fort procedure?
What is Lefort 2 surgery?
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 is a 2 piece Lefort?
The 2-piece Le Fort I maxillary osteotomy begins with an incision placed just lateral to the uvula and carried anteriorly in the midline on to the hard palate ending just lateral to the midline dental gingival papillae (Fig 1). The incision of the soft palate is carried through the full thickness on the nasal side.
