Analysis of Le Fort Ⅰ osteotomy in orthognathic surgery for patients with repaired cleft lip and palate

目的:观察分析Le FortⅠ型截骨术在唇腭裂正颌外科中的应用效果。方法:回顾2004年3月至2006年12月武汉大学口腔医学院口腔颌面外科收治的唇腭裂患者的临床资料,并进行总结与分析,所有患者均进行了以LeFortⅠ型截骨术为主的正颌外科治疗。结果:共收集相关病例16例,其中男9例,女7例,平均年龄22.4岁。术前∠SNA平均73.2°,术后∠SNA平均79.5°;上颌前移距离平均8.13mm。平均随访时间7.3个月。所有患者术后面容改善明显,经正畸治疗后咬合关系满意。结论:以Le FortⅠ型截骨术为主的正颌外科治疗,可以显著改善唇腭裂患者的颌骨与面容畸形。

PURPOSE： To evaluate the effect of Le Fort Ⅰosteotomy in orthognathic surgery for patients with repaired cleft lip and palate. METHODS： Clinical data of patients with facial clefts treated by orthognathic surgery in the department of oral and maxillofacial surgery of Wuhan University from March 2004 to December 2006 were retrospectively reviewed. All patients received Le Fort Ⅰ osteotomy procedure during orthognathic surgery. RESULTS： Data of 16 cases were collected, including 9 males and 7 females with an average age of 22.4 years. The preoperative SNA angle averaged 73.2 degrees, the postoperative SNA angle averaged 79.5 degrees. The distance of maxilla advancement averaged 8.13mm. The average follow-up period was 7.3 months. All patients had a better profile after operation and a satisfactory occlusion after orthodontic treatment. CONCLUSIONS： Le Fort Ⅰosteotomy combined with other orthognathic surgery proved to be an effective method for correction of maxillofacial deformities in patients with facial clefts.
