The self-retained Le Fort I osteotomy.
Because inferior repositioning of the maxilla after Le Fort I osteotomy has a high relapse rate, a modified bone cut oriented obliquely upward has been tried in 29 patients. The modification allows extrusion of the fragment while maintaining good bony contact, thus eliminating the need for bone grafts. It also permits self-retention of the fragment and can be adapted to movements in any plane.
