从根本上说Bell′s麻痹(BP)应是一种于一生中仅可罹患一次的疾病,故复发性Bell′s麻痹(RPB)实属罕见,仅占BP的0.8％～15.2％,BP与RBP之病因学均不明,从RBP患者的面神经减压术中未能证实有缺血因素存在。近年曾有人提出BP因脱髓鞘的急性多神经病(acute polyneuropathy),设想为一种急性病毒感染或潜在病毒的活化所引起。也可能是单纯疱疹病毒引起髓蛋白改变而诱发细胞免疫反应,致颅神经脱髓鞘。为验证此假说作者对面 Bell’s Paralysis (BP) is essentially a disease that can only suffer once in a lifetime, so relapse Bell’s Paralysis (RPB) is rare, accounting for only 0.8% to 15.2% of BP, BP Etiology and RBP are unknown etiology, from RBP patients with facial nerve decompression failed to confirm the presence of ischemic factors. It has been suggested in recent years that BP is caused by an acute viral infection or activation of a latent virus due to demyelinating acute polyneuropathy. May also be caused by herpes simplex virus changes in the protein and induce cellular immune response, resulting in demyelination of cranial nerves. Opposite to verify the author of this hypothesis
