摘    要:目的:探讨kFortI型截骨术上抬上颌骨,下颌骨自动旋转后颏前点的变化与上颌骨上抬量的关系。方法:选取25例单纯采用LeF0rtI型截骨术上抬上颌骨矫治垂直向发育过度的患者.测量手术前、后头颅定位侧位片。采用SPSS13.0软件包对ANS、PNS上抬量与下颌骨颏前点前移量和上抬量进行Pearson相关和线性回归分析。结果:25例样本中.ANS点平均上抬(5.04_+1.20)mm.PNS点平均上抬(3.36+1.24)mm。颏前点平均前移(5.12+2.64)mm,颏前点平均上抬(4.04+2.38)mm。下颌骨颏前点前移量与ANS点的上抬量呈正相关关系(r=0.641,P=0.001)。与PNS点的上抬量呈正相关关系(r:0.602,P=0.001)。下颌骨颏前点上抬量与ANS点的上抬量呈正相关关系(r--0.393,P=0.052),与PNS点的上抬量呈正相关关系(r=0.627,P=0.001)。结论:下颌骨颏前点的位置变化与上颌骨上抬幅度高度相关。

Abstract:PURPOSE: The purpose of the present investigation was to find the interrelation between the magnitude of maxillary surgical impaction and the position change of the pogonion. METHODS: Twenty-five patients who underwent maxillary Le Fort I impaction without concomitant major mandibular ramus split osteotomies were included. The preoperative and postoperative lateral cephalograms were used to evaluate the surgical changes. Statistical analysis was performed to evaluate the interrelation between the magnitude of maxillary surgical impaction and the change of the pogonion by using SPSS 13.0 software package. RESULTS: The magnitude of maxillary ANS point surgical impaction was, in average,(5.04~l.20)mm and the PNS point was, in average, (3.36-+1.24)mm in these 25 patients. The magnitude of pogonion point was, in average, (5.12+2.64)mm forward and (4.04_+2.38)mm upward. The amount of the pogonion point tbrward and the ANS point elevation was positively correlated (r=0.641, P=0.001), the amount of the pogonion point forward and the PNS point elevation was positively correlated (r=0.602, P=0.001). The amount of the pogonion point upward and the ANS point elevation was positively correlated (r=0.393, P=0.052). The amount of the pogonion point upward and the PNS point elevation was positively correlated (r=0.627, P=0.001). CONCLUSION: The magnitude ofmaxillary. ANS and PNS point impaction was highly and positively correlated to tile position change of the pogonion.
