桥小脑角是脑膜瘤好发部位之一,该部位脑膜瘤的发病率占脑膜瘤的10％左右。该部脑膜瘤多起源于岩骨尖后面和附近颅底的硬脑膜。由于解剖关系的特殊,这一部位脑膜瘤是手术中较为困难的一类。桥小脑角肿瘤手术一般采用一侧枕下入路,但较大的肿瘤向幕上生长或长至斜坡,枕下入路全切肿瘤有较大困难。近一年来我们采用颞枕开颅经小脑幕入路切除3例较大的桥小脑角脑膜瘤,取得了良好的效果。现报告如下: 1 病例报告 The cerebellopontine angle is one of the predilection sites of meningioma, the incidence of meningioma in this area accounted for about 10% of meningioma. The Ministry of meningiomas and more originated in the back of the petrous apex and the skull base near the dura. Due to the special anatomy, this site meningiomas is a more difficult category of surgery. Ocular cerebellar angle tumor surgery generally use one side of the suboccipital approach, but larger tumors grow to the curtain or as long as the ramp, suboccipital approach full cut tumor have greater difficulty. In the past year, we adopted the temporal occipital craniotomy via the tentorium to resect the three cases of cerebellopontine angle meningiomas and achieved good results. The report is as follows: 1 case report
