目的：探讨颅内脑膜瘤的复发因素以及预防复发的措施。方法：回顾性总结1986年7月~1997年6月间手术切除的245例脑膜瘤中术后复发的引例。结果：病理类型以恶性脑膜瘤及纤维型脑膜瘤复发率较高；肿瘤部位以蝶骨嵴内1／3及矢状窦旁者复发率较高；行SimpsonⅢ级手术复发例数较多。结论：脑膜瘤的复发与手术切除彻底性、肿瘤部位、病理类型、硬脑膜浸润等有关，预防措施主要是手术彻底切除肿瘤，并可结合放疗、化疗等。
Objective: To explore the recurrent factors of intracranial meningioma and the measures to prevent recurrence. Methods: A retrospective review was made of the cases of recurrent postoperative recurrence in 245 meningioma surgically resected between July 1986 and June 1997. Results: The recurrence rate of malignant meningioma and fibro meningioma was higher in the pathological type. The recurrence rate was higher in the 1/3 of the sphenoid ridge and in the sagittal sinus of the tumor site. There were more cases of Simpson Ⅲ grade recurrence. Conclusions: The recurrence of meningiomas is related to the completeness of resection, tumor location, pathological type and dura mater infiltration. The preventive measures are mainly to completely remove the tumor by surgery and to combine radiotherapy and chemotherapy.
