Stability of Le Fort I osteotomy in maxillary inferior repositioning: review of the literature.

Inferior repositioning of the maxilla to correct vertical maxillary deficiency has been one of the more unstable orthognathic procedures performed. This kind of maxillary movement is the logical correction of short face syndrome due to maxillary vertical deficiency, but in spite of the esthetic improvement that it produces, a great tendency to relapse was observed. Unfortunately, the procedure is relatively rare, and this is reflected in the small sample of the studies. The literature concerning the stability of Le Fort I osteotomy in maxillary inferior repositioning was reviewed to analyze and discuss the stability of the surgical techniques proposed.
