Facial nerve (FN) impacts the function of the facial musculature by creating muscle tone at rest as well as the muscles' voluntary and involuntary contractions. Temporary or permanent loss of FN function could be due to different etiologic factors. Acute facial paralysis (FP) could be significantly stressful for the patient and the family and apart from supportive measures management options are quite restricted. While botulinum toxin (BTX) injection in the FP setting has been used mostly to address the compensatory hyperkinesia in the non-paralyzed side of the face, there are evidence to suggest contralateral injection of the non-paralyzed face with BTX may improve/enhance the recovery time of the FP in cases where the FP has a reversible cause. While further studies are underway, using the current evidence as discussed could potentially justify the current usage of contralateral BTX injection and biofeedback exercises in the setting of the temporary FP specialty due to lack of effective alternative management options.
面神经（FN）通过在静息状态下产生肌张力以及肌肉的自主和非自主收缩来影响面部肌肉组织的功能。FN功能的暂时或永久性丧失可能归因于不同的病因。急性面瘫（FP）对患者及其家人来说可能会造成极大的压力，除了支持性措施外，治疗选择非常有限。虽然肉毒杆菌毒素（BTX）注射在FP治疗中主要用于解决面部未瘫痪侧的代偿性运动亢进，但有证据表明，在FP有可逆病因的情况下，对未瘫痪侧面部进行BTX对侧注射可能会改善/缩短FP的恢复时间。虽然进一步的研究正在进行中，但由于缺乏有效的替代治疗选择，根据所讨论的现有证据，在临时FP专科治疗中使用对侧BTX注射和生物反馈训练可能是合理的。
