Maxillary osteotomy stability
Reviewed by Stuart Clark

This systematic review assesses inferior repositioning of the maxilla six months after surgery. Two articles were identified with a total of 22 patients. The repositioning was of a mean of 3.2 to 4.5mm anteriorly and 0.1 to 1.8mm posteriorly. Six months after treatment there was a mean relapse of 1.6mm anteriorly and 0.3 posteriorly. They acknowledge the various procedures that may be involved in trying to reduce the relapse of this unstable procedure. Inevitably the variables involved in this surgery and the limited sample size resulted in the statement that no significant conclusions could be determined.
