从sir charls氏首次报告贝尔氏面瘫(简称BP)以来已过去一个半世纪,但因其发病原因和病理改变不清,所以一直称之为特发性面瘫,至今还没有人能改变固有观念,确立一个新的病名。不仅如此,在治疗原则上也有争议,尤其对面神经减压术意义的争议更大,这是因为对面神经骨管内的病理缺乏正确认识。到七十年代,对BP虽仍无突破性的认识,但对其病因、病理、而神经变性程度的判断及预后诊断,有不少学者作了深入研究,在治疗上也百家争鸣,治愈率有了提高。一、病因诊断:多数学者认为,面神经水肿和骨管限制面神经肿胀的范围,使面神经受骨管的反作用 It has been more than a century and a half since sir charls first reported Bell’s facial paralysis (BP), but it has been called idiopathic paralysis for its etiology and pathology, and so far no one has been able to change his mind, Establish a new disease name.
