摘　　要：自1990年3月我们对小脑上蚓部肿瘤连续7例采用顶枕部开颅,经小脑天幕行肿瘤切除。4例为血管网织细胞瘤做到全切除,2 例星形细胞瘤近全切除,1 例神经节胶质瘤大部切除,手术效果皆良好。这种手术入路主要优点是:(1)解剖关系清楚,直视下可保留重要的脑结构;(2)操作方便,如肿瘤边界清楚比较容易做到全切除;(3)此部位肿瘤位置高且深,极易梗阻第四脑室上部而致脑积水,肿瘤切除后脑脊液皆能恢复通畅;(4)对小脑牵拉少,不需切断小脑上行的引流静脉,术后反应小。Since March. 1990. we have operatedon 7 cases with parieto-occipital craniotomyand incision of tentorium. Total removal achie-ved in 4 cases with angioreticuloma. andsubtotal removal in 2 cases with astrocytoma.The other 1 cases had gross partialremoval of ganglionic glioma. The operativeresults were excellent in all cases. The mainadvantages of this new approach are as follows:(1) Clear anatomic relation. Important structurescan be preserved under direct vision, (2) Simpleand convenient operation. Total removal of thetumor may be achieved. (3) Removal of tumorcan restore the free circulation of CSF anddecrease the hydrocephalus caused by the highand deep tumor. (4) It doesn't need to ligate cerebellar ascending veins with less postoperativereaction.
