目的 探讨应用下颌骨外板劈除术及颏前下滑行内缩并配合嵌入式植骨术矫治短面型方颌的可行性及效果评价.方法 2005年7月至2009年10月,对57例短面型方颌伴颏部过方、过短及后缩的患者,应用下颌骨外板劈除术及颏前下滑行内缩并配合嵌入式植骨术进行矫治,以缩小下颌宽度、增大下颌平面角、延长并缩窄颏部,从而获得协调流畅的面部轮廓.术前和术后拍摄定位标准面像、X线头影测量片、全景片等,以评价矫正效果.术后进行6～24个月的随访,调查患者满意度.结果 术后57例患者伤口均一期愈合,下颌平面角增大至25°～30°,下颌角开张度增大至120°,两下颌角间距明显减小,下颌整体宽度缩窄,颏部尖翘,下颌轮廓协调,效果评价均满意.结论 联合应用下颌骨外板劈除术及颏前下滑行内缩术,可有效地矫治短面型方颌,使下颌骨轮廓达到较为理想的美学标准.
Objective To evaluate the the feasiblility and effectiveness of narrowing and sliding genioplasty combined with mandibular outer cortex ostectomy technique to reshape a square jaw in short face. Methods From July 2005 to October 2009, a total of 57 patients received narrowing and sliding genioplasty combined with mandibular outer cortex ostectomy procedure to correct square jaw in short face.All the patients had standard frontal and lateral cephalometric radiographs, panoramic radiographs, and were photographed preoperatively and postoperatively to assess their face contour. The alteration of mandibular angle, mental contour and width of lower face was observed for 6 to 24 months postoperatively.Questionnaires were used to assess the patients＇ satisfactory. Results It showed that the postoperative lower face had narrowed and become softer, slender and oval, with a slick mental region. The final aesthetic outcomes were quite satisfactory in all cases from both the view of surgeons and patients.Conclusions Narrowing and sliding genioplasty combined with mandibular outer cortex ostectomy procedure could efficiently adjust the shape and position of chin to obtain a good proportion of the lower face, and to change square and short face to slender oval one by single operation in accordance with the fashionable aesthetics in orientals.
