目的 探讨如何运用显微神经外科技术治疗鞍结节脑膜瘤。 方法 42例鞍结节脑膜瘤中36例行显微神经外科手术，其中11例采用单侧额下入路，17例采用单侧翼点入路，6例采用眶上翼点联合入路，2例早期病例因术前误诊为垂体瘤采用经鼻蝶入路。 结果 按Simpson分级 Ⅰ级22例，Ⅱ级为10例，共占89％；术后视力改善的有14例27眼，无改变的为9例16眼，视力下降的有13例23眼，术前视力完全丧失的术后视力均未恢复。无死亡病例。 结论 术前正确诊断，选择合适的手术入路和应用显微神经外科技术是取得良好疗效的关键。
Objective To explore how to use microsurgical techniques in the treatment of saddle nodular meningioma. Methods Thirty - two patients with saddle nodular meningiomas underwent microsurgical neurosurgery. Eleven patients underwent unilateral inferior frontal approach, 17 underwent unilateral pterional approach, and 6 received supra - superior fossa approach. 2 Cases of early cases of preoperative misdiagnosis of pituitary tumors by transnasal approach. Results According to Simpson grade Ⅰ 22 cases, Ⅱ grade 10 cases, accounting for 89%; postoperative visual acuity improvement in 14 cases 27 eyes, no change in 9 cases 16 eyes, vision loss in 13 cases 23 eyes, Visual acuity after complete loss of anterior vision did not recover. No deaths. Conclusion The correct diagnosis before surgery, select the appropriate surgical approach and the application of micro-neurosurgery technology is the key to good effect.
