摘　　要：目的脑膜瘤以大小分型尚无统一意见,使各文献报道缺乏可比性,有必要找出脑膜瘤大小分型方法和提出分型标准的建议。方法收集手术治疗的428例不同部位脑膜瘤病人资料,根据肿瘤的横径、竖径和矢状径,计算出平均径。以肿瘤的平均径为基础,结合多数作者报道的脑膜瘤大小的分组资料,提出不同部位脑膜瘤大小分型的建议,并讨论其临床意义。结果凸面、矢旁、镰旁、侧脑室、天幕、嗅沟和蝶骨嵴脑膜瘤的平均径为4.11～4-35 cm,可采用相同分型标准;小型,小于或等于3 cm;中型,大于3 cm小于或等于5 cm;大型,大于5 cm。鞍部、颅中窝、桥小脑角、岩斜区、小脑、枕大孔区脑膜瘤的平均径为2.23～3.25cm,可采用相同分型标准:小型,小于或等于2 cm;中型,大于2 cm小于或等于4 cm;大型,大于4 cm。根据提出的分型标准将409例脑膜瘤进行分类,各部位脑膜瘤小、中、大型的数量呈正态分布,分型标准与大多数作者报道相近。结论脑膜瘤平均径比最大径更能代表脑膜瘤的实际大小,也符合临床医生记述的习惯。这种脑膜瘤大小的分型方法简单方便,与多数作者的报道资料接近。对脑膜瘤大小实行统一的分型标准,不仅有利于规范脑膜瘤大小的统计,增加相似报道的可比性,也对脑膜瘤的临床治疗具有指导意义。Objective There is not a unified opinion on the classification of intracranial meningiomas according to their size at present. It is need to find out a method and suggest a criterion of the intracranial meningioma classification according to their size. Methods The clinical data of 428 patients with intracranial meningiomas located in different sites, who were operated on, were reviewed. The horizontal, vertical and seggital diameters were determined and then their average diameter was calculated. The proposal of the classification of intracranial menigiomas was suggested according to their average diameter and other writers data of meningiomas size. The clinical significance of the meningioma classification was discussed. Results The average diameter of cerebral hemisphere convexity meningiomas, parasagittal sinus meningiomas, parafalx meningiomas, lateral ventricular meningiomas, tentorial meningiomas, olfactory groove meningiomas, sphenoid ridge meningiomas was 4.11~4.35 cm, so they were classified according to the same criterion: Minitype ≤ 3 cm in the average diameter, 5 cm ≥ middle type >3 cm, big type>5 cm. The average diameter of tuberculum sellae meningiomas, middle fossa meningiomas, cerebellopontine angle meningiomas, clivus meningiomas, cerebellar convexity meningiomas and meningiomas of the foramen magnum, meningiomas of the orbit and cranioorbit was 2.23~3.25 cm, so they were classified according the same criterion: Minitype ≤2 cm in the average diameter, 4 cm ≥ middle type >2 cm, big type > 4 cm. According to this clas-sificatory criterion the 409 meningiomas were classified, and the amount of minitype, middle type and big type of meningiomas were statistically normal distribution. The classification criterion is close to many writers' opinion. Conclusions The average diameter is closer to true size of meningiomas than their biggest diameter, and also conform to the doctors habit of description. The method of classifying meningiomas is simple and convenient, and also closes to many writers'
