目的探讨颅内外沟通型巨大鞍给节脑膜瘤的诊断与治疗及鞍结节脑膜瘤的分型。方法4例直径为6．8～7.2cm的鞍结节脑膜瘤经双额冠状开颅额下入路切除并肌肉、阔筋膜和生物胚颅底重建。结果肿瘤全切除3例，次全切除1例，颅底重建4例，随访7月至3年，效果良好。结论对首发症状表现为视力减退者，应行CT或/和MR检查，以排除鞍结节脑膜瘤的可能；颅内外沟通型巨大鞍给节脑膜瘤经双额开颅额下入路并肌肉、阔筋膜、生物胶颅底重建效果佳；建议将鞍结节脑膜瘤分为5型：即肿瘤直径在2．5cm以下为小型，2．5～4cm为中型，4～6cm为大型，6cm以上为巨大型，有颅内外沟通者列为颅内外沟通型
Objective To investigate the diagnosis and treatment of meningioma of intracranial and external communicating giant saddle and the classification of saddle nodular meningioma. Methods Four patients with saddle nodular meningiomas with a diameter of 6.8 ~ 7.2cm were resected by the double forehead craniotomy, and muscle, fascia lata and biological embryos were reconstructed. Results Total resection in 3 cases, subtotal resection in 1 case, skull base reconstruction in 4 cases, followed up for 7 months to 3 years, with good results. Conclusion The first symptom of the performance of vision loss, CT or / and MR examination should be performed to rule out the possibility of nodules of meningioma nodules; intracranial and external communicating giant saddle meningioma by double frontal cranial approach and muscle , Fascia lata, bio-plastic skull base reconstruction effect is good; proposed nodular meningioma is divided into 5 types: the tumor diameter of 2.5cm below the small, 2.5 ~ 4cm for the medium, 4 ~ 6cm for the large, 6cm or more for the huge, intracranial and external communication were classified as intracranial communication type
