单侧性颜面神经麻痹可分为末梢颜面神经痹后单侧颜面神经麻痹及隐性单侧神经麻痹,对于后者,1875年Schultze首次道因椎动脉瘤引起。作者对35例经开颅术后确诊的后颅窝血管压迫颜面神经作了研究,全部病例均作了汤氏位及侧位摄影,并与非患侧25例及无颅内病变及颜面神经麻痹的25例对照,发现颜面神经麻痹多有轻度动脉硬化性改变。文内35例中29例(83%)有轻度动脉硬化。可见桥小脑角脑沟内椎动脉屈曲、蛇形改变。患侧(31%),比患侧(8%)及非颜面神经麻痹病例(20%)多。另外,小脑前下动脉与小脑后下动脉干者35例中有25例(66%),而非患为40%颜面神经麻痹者为28%。压迫颜面神经时
Unilateral facial nerve paralysis can be divided into facial facial nerve paralysis after unilateral facial nerve paralysis and occult unilateral nerve paralysis, for the latter, Schultze for the first time in 1875 caused by vertebral aneurysm. The authors studied 35 cases of posterior cranial fossa with facial nerve compressed after craniotomy. Thirty-two patients were enrolled in this study. Thirty-two patients with non-ipsilateral and non-intracranial lesions and facial nerve 25 cases of paralysis control and found that facial nerve paralysis and more mild changes in atherosclerosis. Among the 35 cases, 29 cases (83%) had mild arteriosclerosis. Can be seen bridge cerebellar angle sulci vertebral artery buckling, serpentine change. The affected side (31%) was more affected than the affected side (8%) and non-facial paralysis (20%). In addition, 25 of 35 (66%) had anterior inferior cerebellar artery and posterior inferior cerebellar artery artery, compared with 28% of non-affected facial nerve paralysis (40%). When pressing the facial nerve
