讨论上矢状窦旁脑膜瘤手术治疗的手术方式、切除范围、矢状窦损伤修补或重建问题。方法总结１９８７～１９９６年手术治疗３５例上矢状窦旁脑膜瘤的经验。肿瘤大小，３ｃｍ×４ｃｍ×５ｃｍ１１例，６ｃｍ×８ｃｍ×１０ｃｍ２４例。结果３５例肿瘤全切除２７例，次全切除８例，无２例死亡。术后复发２例而行二次手术切除。结论矢状窦旁脑膜瘤因生长部位、侵犯矢状窦范围不同，采用手术方式不同。总的原则骨窗够大，暴露要充分，肿瘤切除包括受侵犯颅骨、硬脑膜、静脉窦壁，肿瘤分块或整块切除，以达到肿瘤根治，防止复发。切除肿瘤侵袭矢状窦壁，应行矢状窦修补和重建，并要保护中央沟静脉及其它重要引流静脉 Discuss the surgical approach, resection range, sagittal sinus injury repair, or reconstruction issues for surgical treatment of parasagittal meningiomas. Methods We summarized the experience of surgical treatment of 35 cases of superior sagittal sinus meningioma from 1987 to 1996. The tumor size was 11 cases in 3cm x 4cm x 5cm and 24 cases in 6cm x 8cm x 10cm. Results Thirty-five patients underwent total tumor resection in 27 cases, subtotal resection in 8 cases, and no death in 2 cases. Two cases of postoperative recurrences underwent secondary resection. Conclusion The sagittal sinus meningioma has different surgical sites due to different sites of growth and invasion of the sagittal sinus. The general principle is that the bone window is large enough to be fully exposed. Tumor resection includes violation of the skull, dura mater, venous sinus wall, tumor mass or whole block resection to achieve tumor cure and prevent recurrence. Resection of the tumor invading the sagittal sinus wall should be performed with sagittal sinus repair and reconstruction and protection of the central sulcus vein and other important draining veins
