Bell's palsy (BP) is an idiopathic peripheral facial nerve paralysis of sudden onset. Its most alarming symptom is unilateral facial weakness, which can result in the inability to close the eyelids, smile, or whistle. The pathogenesis of BP is controversial and is believed to be caused by inflammation of the facial nerve at the geniculate ganglion. Many viruses, especially herpes simplex and herpes zoster, have been suggested as initiators of this inflammatory process; however, this has not been proven. This report describes the case of a 14-year-old girl with right hemifacial palsy who sought treatment one month after the onset of palsy. The patient experienced a satisfactory recovery within 30 days of treatment and has maintained a stable physical outcome after 15 months of follow-up. Early treatment based on careful investigation of BP, with particular attention given to the differential diagnosis of BP, can improve the patient's function and esthetics.
贝尔麻痹（BP）是一种突发的特发性周围性面神经麻痹。其最令人担忧的症状是单侧面部无力，这可能导致无法闭眼、微笑或吹口哨。BP的发病机制存在争议，被认为是由膝状神经节处的面神经炎症引起的。许多病毒，尤其是单纯疱疹病毒和带状疱疹病毒，被认为是这种炎症过程的引发因素；然而，这一点尚未得到证实。本报告描述了一名14岁右侧面瘫女孩的病例，她在面瘫发作一个月后寻求治疗。患者在治疗30天内恢复良好，随访15个月后身体状况保持稳定。基于对BP的仔细检查进行早期治疗，尤其注重BP的鉴别诊断，可改善患者的功能和美观。
