The authors collected 114 cases of intracranial meningioma surgically treated from January 1956 to 1979. The follow-up ranged from 1 to 23 years.The ratio of male to female was 1: 1.7, while that of female was 62.3% (71 cases). The first operative age was 1 ~ 1/2 ~ 82 years old (average 55 years old), most of which were 60 years old and 70 years old. The common sites of tumors were: sphenoid wing in 27 cases (23.7%), brain convex in 24 cases 17 cases (14.9%) were sinusoids and 60% of 114 cases were found in these three sites.According to Simpson’s classification, the tumors were divided into 5 grades: 33 cases (28.9%) of grade 1, 55.2 cases (48.2% , Grade 3 in 7 cases (6.1%), grade 4 in 18 cases (15,8%) in grade 5 in 1 case (0.9%), grade 1 and 2 accounted for 77.2% .Histological diagnosis: polykaryotic and transitional type accounted for 76.3% , Malignant in 3 cases and angioblastoma in 1 case.The number of postoperative deaths was 8 cases (7%), the recurrences were in 22 cases (19.3%), the interval of non-recurrence was 5,10 and 20 years 80%, 70% and 50%.
