目的:总结前颅底、蝶骨嵴大型脑膜瘤显微手术治疗经验。方法:对21例前颅底、蝶骨嵴大型脑膜瘤患者的影像学资料、手术入路、显微手术切除的方法及疗效进行分析。结果:按照Simpson切除标准,本组21例中Ⅰ级切除14例,Ⅱ级切除2例,Ⅲ级切除1例,Ⅳ级切除4例;术后复发1例再次手术切除;术中无死亡或出现凶险大出血病例。结论:肿瘤全切除是预防复发的有效措施,充分的术前影像学检查及评估,术中保护重要神经与血管,能明显提高肿瘤的全切除率,减少并发症。
Objective: To summarize the experience of microsurgical treatment of anterior skull base and sphenoid ridge meningiomas. Methods: The imaging data, surgical approach and microsurgical resection of 21 cases of anterior skull base and sphenoid ridge meningioma were analyzed. Results: According to the Simpson resection standard, 14 cases of grade Ⅰ resection, 2 cases of grade Ⅱ excision, 1 case of grade Ⅲ excision and 4 cases of grade Ⅳ excision were performed in 21 cases of this group. One case was recurred after operation and no death or A case of dangerous bleeding. Conclusion: Tumor resection is an effective measure to prevent recurrence. The adequate preoperative imaging examination and assessment can protect the important nerves and blood vessels during operation and can significantly improve the total resection rate and reduce the complications.
