大型听神经瘤显微切除术中电生理监测的临床意义

目的:探讨大型听神经瘤显微切除术中电生理监测对面神经功能的保护技巧及意义。方法:以2008年10月～2012年2月术中行电生理监测者为监测组(n=37),2006年1月～2008年7月术中未行电生理监测者为对照组(n=31)。统计分析两组肿瘤全切除率、面神经解剖和功能保留率。结果:监测组的肿瘤全切除率、面神经解剖和功能保留率均明显高于对照组(P<0.05)。结论:听神经瘤术中行电生理监测可有效保护面神经功能。

Clinical significance of neurophysiological monitoring in microsurgery for large acoustic neuroma

Objective: To assess the clinical significance of applying neurophysiological monitoring to preventing the facial nerve from injury during microsurgery of large acoustic neuroma.Methods:Between Oct.2008 and Feb.2012,37 patients with large acoustic neuroma undergone microsurgery assisted with neurophysiological monitoring were recruited as monitored group,while another 31 undergone the similar surgery between Jan.2006 and Jul.2008 without monitoring were included in control group.Two groups were statistically compared regarding the total resection rate for the tumor,rates for both facial anatomical retaining and intact facial nerve function.Results:The results were significantly better in the monitored group than the control group concerning the total resection rate for the mass,retained anatomical facial nerve and facial nerve function preserved(P<0.05).Conclusion:Applying neurophysiological monitoring to microsurgery for large acoustic neuroma may lead to preservation of facial nerve function.
