Abstract

Performing genioplasty for greater stability of the changed chin position, incision, dissection, osteotomy design and fixation are important technical considerations. Basically, wire osteosynthesis method has been used in genioplasty,but plate/screw osteosynthesis has been introduced in rigid fixation. The purpose of this study is that comparison of stability between wire and plate/screw osteosynthesis in genioplasty. In this study,the genioplasty groups were divided into three groups ; advanced genioplasty group, reduction genioplasty group,advanced with reduction genioplasty group. In wire osteosynthesis groups, there were 15patients who had advanced genioplasty,13patients who had reduction genioplasty,and 12patients who had advanced with reduction genioplasty. In plate/screw osteosynthesis groups,there were 15patients who had advanced genioplasty, 13patients who had reduction genioplasty, and 13patients who had advanced with reduction genioplasty. Lateral cephalograms ; pre-and postoperatively,postoperatively 1months, and at the latest follow-up (>6months); were analyzed by linear measurement to evaluate changes in position (hard tissue B, Pogonion point)and compare relapse between both groups.
