摘要本研究旨在探讨神经外科手术对听力的影响。32例患者接受了神经外科手术，32例患者接受了不涉及硬膜下腔穿刺或引流的手术，作为对照组。在神经外科组中，在术后即刻观察到明显的听力损失，并在一周内恢复。在对照组中未观察到平均阈值偏移。这表明，在神经外科手术后，听力损失的机制直接来自脑脊液的压力和/或体积的降低，这反映在外淋巴液中，与暂时性内淋巴积水相当。
Abstract A prospective study was performed to investigate the effect of neurosurgery on hearing. Thirty-two patients underwent neurosurgery while 32 patients who had surgical procedures not involving puncture or drainage of the subdural space, served as a control group. In the neurosurgical group, a significant loss of hearing was observed in the immediate post-operative period, with recovery over one week. No average threshold shift was observed in the control group. It is suggested that following neurosurgery the mechanism of hearing loss results directly from a decrease in pressure and/or volume of the cerebrospinal fluid, which is reflected within the perilymphatic fluid, comparable to a transitory endolymphatic hydrops.
