背景：这项观察性研究的目的有两个：(1)展示一种量化面瘫患者面部软组织运动受损的方法和措施；(2)量化面瘫患者和对照组之间面部软组织运动的幅度和速度的差异。方法：研究样本包括20名急性、单侧、松弛性面神经麻痹患者和20名健康成年人。在11个面部动画过程中，从每个参与者那里收集了动态3D面部运动数据。为了比较患者和对照参与者之间的运动，计算了平均面部运动的动态建模比较以及每个动画的运动向量曲线图，此外，还计算了最大位移、运动速度和不对称性的测量。结果：关键面部地标的动态3D建模提供了特定区域不对称的精确轮廓和个性化报告，突出了个体患者的重要区域。动态3D运动数据证实，患者非瘫痪侧面部有异常的方向性运动。正如预期的那样，控制组在所有动画中都有明显更高的离散性面部运动，除了温和闭眼的时候，这对患者来说更大，控制组的运动速度明显高于患者。患者对所有动画都有明显更大的不对称性，并且不对称性的层次是最大限度地微笑；嘴唇钱包；鬼脸；脸颊浮肿。结论：动态3D建模似乎是一种有效的工具，可以为面瘫患者提供特定区域不对称的精确轮廓和定制报告。
Background:The aims of this observational study were 2-fold:(1) To demonstrate a method and measures to quantify impaired facial soft-tissue movements in patients with facial paralysis; and (2) To quantify the differences in magnitude and velocity of facial soft-tissue movements between patients with facial paralysis and control participants.Methods:The study sample that addressed both aims consisted of 20 adults with acute, unilateral, flaccid facial paralysis who presented at the onset of their paralysis, and a control group of 20 healthy adults. Dynamic 3D facial movement data were collected from each participant during 11 facial animations. To compare the movements between the patients and control participants, dynamic modeling comparisons of mean facial movements were computed as well as plots of movement vectors for each animation, in addition, measures of maximum displacement, movement velocity, and asymmetry were computed.Results:Dynamic 3D modeling of critical facial landmarks provided precise profiles of zone-specific asymmetries and customized reporting that highlighted areas of importance for individual patients. The dynamic 3D movement data confirmed that the nonparalyzed side of patients’ faces had abnormal directional movements. As expected, the controls had significantly higher excursive facial movements during all animations except during gentle eye closure, which was greater for the patients and the controls had significantly greater movement velocity than the patients. The patients had significantly greater asymmetry for all the animations, and the hierarchy of the asymmetry was such that maximum smile> lip purse> grimace> cheek puff.Conclusion:Dynamic 3D modeling appeared to be an effective tool to provide precise profiles of zone-specific asymmetries and customized reports for patients with facial paralysis.
