Abstract
Correction of disorders during transformation into one of the most difficult tasks, both in orthodontics and in maxillofacial (orthognathic) surgery. This article presents two clinical cases of median osteotomy/ostectomy. The stages of operations are described. Surgical technique of transversal correction by osteotomy/ ostectomy is presented. Operation is combined with bilateral retromolar osteotomy. Three dimensional fragments moving helps to change lower jaw shape. Indications for this surgical manipulation: one or two side cross-bite, discrepancies between size of teeth and length of alveolar bone (lower macrognathia, microdentia, extra-teeth, huge diastema), asymmetry of mandible.
