目的 探讨听神经瘤显微手术保留听神经功能及其影响因素。方法 收集我院近 2年来 2 3例经枕下乙状窦后入路显微手术的初发听神经瘤资料 ,其中包括肿瘤大小、术前术后听力、肿瘤内听道底侵蚀及术后小脑损伤情况。结果 耳蜗神经解剖保留 1 9例 ,保留有效听力 2例 (占术前存在有效听力患者的 33 3 % ) ,有效听力丧失保留可测听力 1 0例。听力的保留与肿瘤大小、术前听力水平、肿瘤内听道底侵蚀、小脑损伤相关。结论 肿瘤的大小、术前听力水平、肿瘤内听道底侵蚀和小脑损伤是听神经瘤术后听神经功能保留的影响因素。
Objective To investigate the effect of microsurgery on auditory nerve preservation of acoustic neuroma and its influencing factors. Methods The data of 23 patients with subacute retrosigmoid posterior approach microsurgery in our hospital in recent 2 years were collected, including tumor size, preoperative and postoperative hearing, intracranial auditory canal edema and postoperative cerebellar Injury situation. Results There were 19 cases of cochlear nerve anatomy, 2 cases of effective hearing (33.3% of patients with effective hearing before operation) and 10 cases of measurable hearing loss. The retention of hearing correlates with the size of the tumor, the level of preoperative hearing, the erosion of the auditory lining in the tumor, and cerebellar injury. Conclusion The size of tumor, preoperative hearing level, intra-tumor eosinophilic erosion and cerebellar injury are the influencing factors of auditory nerve function retention after acoustic neuroma.
