Twenty-five Chinese patients who had undergone advancement genioplasty were evaluated for soft tissue changes of chin. The effects of bony genioplastic advancement on soft tissues of profile were studied by means of computerized cephalometric analysis. The change ratios between soft tissue and hard tissue, as well as regression equations were calculated. The result of this study led to the following conclusions: The soft tissue chin point and labiomental sulcus moved by 85% and 41% of horizontal advancement of the mandibular symphsis.
对25例接受颏前移术的中国患者的颏部软组织变化进行了评估。通过计算机头影测量分析研究了骨性颏成形术前移对侧面软组织的影响。计算了软组织与硬组织之间的变化率以及回归方程。本研究结果得出以下结论：软组织颏点和唇颏沟移动的距离分别为下颌联合水平前移距离的85%和41%。
