目的 :总结小脑幕脑膜瘤显微手术的经验和教训 ,以利提高手术的疗效。 方法:采用经颞枕硬膜内入路、枕部经小脑幕与枕下联合入路、枕下内侧入路、旁正中入路 ,均采用显微神经外科技术切除肿瘤。结果 :肿瘤全切除 6例 ,次全切除 2例。术后死亡 1例 ,共济失调 1例 ,构音障碍和饮水咳呛 1例 ,5例痊愈。结论 :小脑幕脑膜瘤切除应选择合适的手术入路。手术时必须切除窦内肿瘤 ,在切除肿瘤侵入的横窦前 ,必须有血管造影完全闭塞的证据。脑干附近的肿瘤先行包膜内切除 ,后切除肿瘤包膜
Objective: To summarize the experience and lessons of microsurgical operation of cerebellar meningioma in order to improve the curative effect of surgery. Methods: The transurethral epidural approach was used. Occipital occipital commissures and suboccipital conjunctival approach, suboccipital medial approach, and paracentesary approach were performed with microsurgical neurosurgical techniques. Results: Total resection in 6 cases, subtotal resection in 2 cases. 1 case died of postoperative death, 1 case of ataxia, 1 case of dysarthria and drinking cough and 5 cases recovered. Conclusions: Appropriate surgical approaches should be chosen for the removal of cerebellar meningiomas. Surgery must be removed within the sinus tumor, in the removal of tumor invasion before the transverse sinus, angiography must be completely occlusion evidence. Tumors in the brain stem near the first removal of the capsule, after removal of the tumor capsule
