摘要
目的探讨桥小脑角池及内耳道内冗长血管袢压迫前庭蜗神经是否是引起搏动性耳鸣的病因之一。方法回顾性分析83例单侧搏动性耳鸣患者的MRI资料,统计耳鸣侧与非耳鸣侧冗长小脑前下动脉压迫桥小脑角池段前庭蜗神经及冗长迷路动脉压迫内耳道段蜗神经的发生频度有无显著性差异。结果 83例患者中,43例耳鸣侧及41例非耳鸣侧发生冗长小脑前下动脉压迫桥小脑角池段前庭蜗神经,4例耳鸣侧和2例非耳鸣侧发生冗长迷路动脉压迫内耳道段蜗神经。统计分析显示耳鸣侧与非耳鸣侧冗长小脑前下动脉压迫桥小脑角池段前庭蜗神经、冗长迷路动脉压迫内耳道段蜗神经的发生频度均无显著性差异(P>0.05)。结论冗长小脑前下动脉压迫前庭蜗神经及冗长迷路动脉压迫蜗神经并不是引起搏动性耳鸣的原因。
OBJECTIVE To evaluate whether the vestibulocochlear nerve vascular compression is one of causes of pulsatile tinnitus（PT）.METHODS We retrospectively analyzed MRI data of 83 patients with PT,and determined whether there were significant difference in the incidence of the vestibulocochlear nerve vascular compression between PT and normal side in the cerebellopontine angle cistern and internal auditory canal respectively.RESULTS Among of 83 patients with PT,the vestibulocochlear nerve vascular compression in cerebellopontine angle cistern occurred on 43 PT sides and 41 normal sides,and the cochlear nerve vascular compression in internal auditory canal on 4 PT sides and 2 normal sides.There were no statistically significant differences between the PT side and the normal side in the incidence of the vestibulocochlear nerve vascular compression in cerebellopontine angle cistern and the cochlear nerve vascular compression in internal auditory canal.CONCLUSION The vestibulocochlear nerve and/or cochlear vascular compression are not the cause of PT.
