神经内镜辅助听神经鞘瘤显微手术11例分析

目的总结应用神经内镜辅助显微镜治疗听神经鞘瘤的效果。方法对11例听神经鞘瘤交替使用神经内镜及手术显微镜,对（该区域神经内镜下解剖）手术治疗进行回顾性分析和总结。结果肿瘤均全切,全部面神经解剖结构完整,4例保留听力,无死亡病例及严重并发症发生。结论神经内镜在该区手术中明显改善深部术野的照明和显微解剖结构的识别,减少对小脑/脑干牵拉,弥补手术显微镜的不足,对显微手术起到重要辅助作用。

Microsurgery for Acoustic Neurilemoma with Neuroendoscope Report of 11 Cases

Objective To summarize the results of microsurgery with neuroendoscoppe in treatment of portio mollis acoustic neurilemoma.Methods Eleven patents with portio mollis acoustic neurilemoma were treated alternately with neuroendoscope and surgical microscope（this part dissection under nerve endoscopy）.The retrospective analysis and summerization were conducted.Results In this group,the overall resection of tumors was carried out and all the facial nerve structures were complete.Four patientsremained the listening ability.Neither death nor severe neuropathy occurred.Conclusions The neuroendoscope used in the said partoperation improves prominently the deep operational part illumination and identification ofmicroscopic dissectional structure and plays an important assistant role in reduction of cerebel/brain stem traction,compensation of the deficits in surgical microscope and aid of microscopic surgery.
