摘要
目的探讨Le FortⅠ型骨切开术在矫治陈旧性面中部骨折所致颌骨畸形的应用价值。方法对42例陈旧性面中部骨折所致颌骨畸形的患者,通过螺旋CT及三维重建、模型外科分析、咬导板制作等准备,术中采用Le FortⅠ型骨切开术对本组病例进行治疗,观察患者术后面部畸形及咬关系的恢复情况,分析Le FortⅠ型骨切开术对颌骨畸形以及咬关系的矫治效果。结果本组42例患者中39例的面部形态和咬关系恢复良好,有3例患者术后咬关系欠佳,经正畸治疗后恢复正常,无严重手术并发症发生。结论 Le FortⅠ型骨切开术是治疗陈旧性面中部骨折所致颌骨畸形的有效方法,可取得满意的治疗效果,值得在临床中进一步推广应用。
Objective To investigate the effects of Le Fort I osteotomy in the treatment ofjaw deformities caused by midfacial old fractures. Methods 42 cases of midfacial old fractures with jaw deformities were treated by Le Fort I osteotomy based on preoperative Spiral CT and 3D reconstruction. Model surgery was performed on occlusal guide preoperatively. The rehabilitation of facial deformity and occlusion was observed postoperatively. The effects of Le Fort I osteotomy for correcting midfacial old fractures were analyzed. Results The facial morphology and occlusion of 39 cases among 42 patients recovered well. Among which, 3 eases had postoperative malocclusion, but healed completely after orthodontic treatment. There were no severe complications happened postoperatively in all cases. Conclusion Le Fort I osteotomy is an important and effective method for correcting jaw deformities caused by midfacial old fractures.
