Facial synkinesis is an involuntary activation of muscles innervated by the zygomatic or mandibular branch of the facial nerve in conjunction with voluntary activation of the other branch. It appears frequently after recovery from peripheral facial nerve paralysis. We report 10 patients with facial synkinesis following Bell's palsy with a mean duration of synkinesis of 7 +/- 4 years before treatment with periorbital injections of Botulinum toxin type A. 9 had marked subjective and objective improvement starting a few days after injection and lasting 4-9 months. The results suggest a useful treatment option for post-Bell's palsy facial synkinesis with Botulinum toxin type A.
面部联动是指面神经颧支或下颌缘支支配的肌肉在面神经其他分支的随意运动时出现的不自主激活。它常在周围性面神经麻痹恢复后频繁出现。我们报告了10例贝尔面瘫后出现面部联动的患者，在进行眶周注射A型肉毒杆菌毒素治疗前，面部联动的平均持续时间为7±4年。9例患者在注射后数天开始有明显的主观和客观改善，持续4 - 9个月。结果表明，A型肉毒杆菌毒素是治疗贝尔面瘫后面部联动的一种有效治疗选择。
