title: Le Fort III osteotomic variants.
abstract: BACKGROUND
  Midface hypoplasia is a skeletal defect involving all three space planes, hence needing a three-dimensional repositioning. This research study shows two cases of cranio-facial dysostosis, on which two Le Fort III variants were performed.
  
  
  METHODS
  In the first case we report the performing the two types of osteotomy simultaneously. Le Fort I, however, has been performed without any pterygomaxillary disjunctions, thus accomplishing a complete midface mobilization without any variation of the occlusal ratios. In the second case a modified Le Fort III osteotomy has been performed with median disjunction; reduction of the transverse interdacryal diameters and of the pyriform opening.
  
  
  CONCLUSIONS
  Among all osteotomic variants we would like to mention the one introduced by Obwegeser in 1969 where, in patients with acceptable dental occlusal ratios, Le Fort III and Le Fort I have been performed in conjunction. This technique allows a different midface and dental occlusion repositioning.
  
  
  CONCLUSIONS
  In adult patients with permanent dentition and normal occlusal ratios this technique may be chosen for a midface advancement without compromising the dento-skeletal relations, in order to achieve the best functional and aesthetical results.
