BACKGROUND
Most cases of facial asymmetry involve yaw deformity, and determination of the yaw correction level is very difficult.
METHODS
We use three-dimensional soft tissue simulation to determine the yaw correction level. This three-dimensional simulation is based on the addition of cephalometric prediction to gradual yaw correction. Optimal yaw correction is determined visually, and an intermediate splint is fabricated with computer-aided design and computer-aided manufacturing. Application of positioning devices and the performance of horseshoe osteotomy are advisable.
RESULTS
With this procedure, accurate repositioning of jaws was confirmed and patients obtained fairly good facial contour.
CONCLUSIONS
This procedure is a promising method for a widespread, predictable treatment of facial asymmetry.
背景
大多数面部不对称病例涉及偏斜畸形，而确定偏斜矫正水平非常困难。
方法
我们使用三维软组织模拟来确定偏斜矫正水平。这种三维模拟基于在逐渐的偏斜矫正中加入头影测量预测。通过视觉确定最佳偏斜矫正，并使用计算机辅助设计和计算机辅助制造制作中间夹板。建议应用定位装置并进行马蹄形截骨术。
结果
通过该手术，证实颌骨得到了准确复位，患者获得了相当不错的面部轮廓。
结论
该手术是一种有前景的方法，可广泛、可预测地治疗面部不对称。
