Le Fort Osteotomy

What is a Le Fort Osteotomy?

The Le Fort Osteotomy is a type of jaw surgery used to correct an abnormally positioned jaw that gives rise to malocclusion problems (misalignment of the teeth and jaw). There are three types of Le Fort Osteotomies:

Le Fort I Osteotomy

This osteotomy is the “work horse” procedure for moving the upper jaw in the treatment of upper jaw malocclusion and cleft palate.

The Le Fort I Osteotomy procedure was invented over 50 years ago and has been done thousands of times and is very safe and useful in that it results in the ability to position the upper jaw anywhere in 3 dimensions in order to shape the face and improve the bite.

This procedure is chosen most commonly when the upper jaw needs to be moved forward and the nose and cheeks are not involved in the problem.

Le Fort II Osteotomy

The Le Fort II Osteotomy is different in that the nose and upper jaw will move together. One of the rarer osteotomies because it isn’t required as often (only in 2-5% of cases such as Treacher Collins or in very unique cases) this osteotomy allows for lengthening of the nose along with movement of the upper jaw in select cases where this effect is desired.

Le Fort III Osteotomy

The Le Fort III procedure is designed the move the entire face forward including portions of the eye sockets in order to get a more harmonious appearance in those in whom facial disharmony results from pan-facial hypoplasia. Used in the treatment of mid-face problems and deficiencies.
