Abstract
|
|
|
|
A LeFort I osteotomy become increasingly popular because three dimensional correction is possible for treating skeletal Class III patients and has low complication rates. The purpose of this study was to describe the stability of the LeFort I osteotomy through review of the literature. An online search for studies in English was performed using MEDLINE, pre-MEDLINE. Publications from 1970 to 2008 were selected based on the following search terms: LeFort I osteotomy, stability, relapse, orthognathic surgery, two jaw surgery. It has been shown that the posterior and inferior movement of maxillary fragment is sensitive to skeletal relapse by the tension of soft tissues. However, surgical stability of LeFort I osteotomy can be achieved by various surgical techniques such as bone graft, rigid fixation using various methods or intermaxillary fixation. LeFort I osteotomy is thought to be a stable surgery, aesthetically as well as functionally satisfactory results may be obtained.
