To quantify the effects of facial palsy reanimation, 14 patients aged 17-66 years were analysed. All patients had unilateral facial paralysis, and were candidates for surgical masseteric to facial nerve anastomosis. Two patient groups were measured: seven patients were waiting for surgery, the other seven patients had already been submitted to surgery, and had regained facial mimicry. Each patient performed three facial animations: brow raise; free smile; lip purse. These were recorded using an optoelectronic motion analyser. The three-dimensional coordinates of facial landmarks were obtained, their movements were computed, and asymmetry indices calculated (differential movements between the two hemi-faces: healthy and paretic/rehabilitated). Before surgery, mobility was larger in the healthy than in the paretic side; after surgery, the differences were reduced (brow raise and lip purse), or even reversed (smile). Before surgery, lip purse was performed with significant labial asymmetry (p=0.042; larger healthy side movement). After surgery, asymmetry indices reduced. Total labial asymmetry during smiling was significantly different from 0 before surgery (p=0.018, larger healthy side movement). After surgery, all asymmetry indices became non-significant. Before surgery the lateral displacements of all labial landmarks were towards the healthy side, while they normalized after surgery.
为了量化面瘫再神经支配的效果，分析了 14 名年龄在 17-66 岁的患者。所有患者均为单侧面瘫，且为接受咬肌-面神经吻合术的手术候选人。测量了两组患者：7 名患者正在等待手术，另 7 名患者已接受手术并恢复了面部表情。每位患者进行了 3 种面部动画：皱眉；自由微笑；撅嘴。使用光电运动分析器记录这些动画。获得面部标志点的三维坐标，计算它们的运动，并计算不对称指数（两侧之间的差异：健康侧和患侧/康复侧）。手术前，健康侧的运动幅度大于患侧；手术后，差异缩小（皱眉和撅嘴），甚至相反（微笑）。手术前，撅嘴时存在明显的唇不对称（p=0.042；健康侧运动幅度较大）。手术后，不对称指数降低。术前微笑时的总唇不对称与 0 有显著差异（p=0.018，健康侧运动幅度较大）。手术后，所有不对称指数均变得无统计学意义。术前所有唇标志点的侧向位移均朝向健康侧，而手术后则恢复正常。
