摘　　要：目的研究下颌前突伴上颌骨发育不全患者术后颜面软组织侧貌改变。方法对20例下颌前突伴上颌骨发育不足病例进行术前后Χ线头影测量研究,用SPSS软件对测量值进行统计分析。结果下唇突点(LI点)、颏唇沟点(Si点)软组织颏前点(PG点)分别以下中切牙点(li点)下牙槽座点(B点)硬组织颏前点(pg点)的92%、97%、92%后移而后移,并得出了相应的回归方程。结论上颌软硬组织改变无明显相关性,下颌软硬组织改变有非常显著相关性。Objective To study the changes of the lateral soft tissue profile of the patients who had mandibular prognathism with maxillary deficiency. Methods X-ray cephalometry of 20 consecutive patients was taken before and after operation . All data were analyzed by SPSS software. Results The mean ratios of soft tissue to hard tissue were as follows ： LI ： li = 0. 92 ; Si ： B = 0. 97 ; PG ： pg = 0. 92. Regression formula was established. Conclusion There wash ＂t a correlation between maxillary soft tissue and hard tissue changes, but there was a correlation between mandibular soft tissue and hard tissue changes.
