摘要
为探讨听神经瘤手术切除经验 ,提高肿瘤全切率和面、听神经保留率 ,本研究回顾性分析枕下 -乙状窦后入路 4 8例听神经瘤显微手术 ,并对手术要点、肿瘤大小与肿瘤全切率和面、听神经保留率之间的关系进行了讨论。如果 13例小于 2cm的肿瘤均全切 ,18例 2～ 4cm的肿瘤 ,全切 16例 ,17例大于 4cm的肿瘤 ,仅 10例全切。肿瘤全切除率 81 3% (39/ 4 8) ,面神经解剖保留率 77 1% (37/ 4 8) ,功能恢复率 6 6 7% (32 / 4 8) ,术前有听力者听神经保留率 52 3% (11/ 2 1)。作者认为肿瘤大小与肿瘤全切率及面、听神经保留率密切相关。应用显微外科技术、采取正确的肿瘤切除方法 ,是提高听神经瘤手术切除率和面、听神经解剖保留率的关键。
To study surgery experience of acoustic neuroma,so as to improve the rate of tumor removing,and the rates of preserving facial nerve and auditory nerve.A retrospective analysis of 48 cases of acoustic neuromas which were treated by microsurgery with Suboccipito-Retrosigmoidal approach.Authors discussed the surgical main points,and their relationship between tumor size and total removal,and rates of facial nerve and auditory nerve preservation.The results showed that the total removal rate was 81 3%(39/48).The rate of facial nerve preservation in anatomy was 77 1%(37/48),and the functional recovery was 66 7%(32/48).Preservation of hearing nerve was 52 3%(11/21).The data suggest that there is closely relation ship between tumor size and total removal rate of tumor,and the preservative rates of facial nerve and auditory nerve.A minimally invasive microsurgical treatment is crucial for increasing total removal rate of tumor,and the preservative rate of facial nerve and auditory nerve.
