Switching Genioplasty - a New Genioplasty Technique in Order to Resolve Asymmetry of Chin Area: Case Report

摘要: Abstract Switching Genioplasty- a New Genioplasty Technique in Order to Resolve Asymmetry of Chin Area: Case Report Hyun-Soo Seo, Young-Joo Lee, Kwang-Seob Byeon, Soon-Min Hong, Jun-Woo Park, Ji-Sook Hong 1 , Yang-Ho Park Departments Oral & Maxillofacial Surgery, Clinical Orthodontics, Kang-dong Sacred Heart Hospital, College Medicine, Hallym Un iversityConventional slinding genioplsty has the risk mental nerve i njury after operation and difficult correct vertical asymmet ry chin. So, authors propose new genioplasty asymm etry is modification method conventional genioplasty. Between mandibular right left canine, osteotomy line triangular shape make until mandibula r lower border. In large side, osteotome wedge dded reduction. After osteotomy, segment was separated from Distal rotated reductio n side. Because rotation distal segment, space made opposite Seperated segement side switched this fill. stability achieved. Authors applied swiching th e patients who remained chin asymmetry both sagittal split ramus done because mandible asymme try. operation, patient operator were satisfied with excellent esthetic results without any other complication. The switching effective surgical technique for it more advantages than sliding First, donor does not need bone graft. Second, can reduce fection, resroption, dehiscence, capsular contraction allograft. Third, have little damage. Forth, anteroposterior correction possible. Fifth, time less asymmetry.
