本文报告了1978～1986年间的63例视神经脑膜瘤与胶质瘤有关诊断和治疗方面的经验.这些患者均为单侧视神经受累,未累及视交叉.其中28例为视神经胶质瘤(年龄为14～56岁,单侧视力从0.5降至无光感,女性多见.),35例视神经脑膜瘤(年龄为14～60岁,单侧视力从0.9降至无光感,女性多见.).均采用经额入路,但由于视神经胶质瘤主要在视神经鞘内膨胀性生长,而脑膜瘤却对邻近结构尚有浸润.故二者的术式尚有异.对于视神经胶质瘤,先将颅内段肿瘤连同视交叉至视神经管间增粗的视神经一并切除.双极电凝视交叉与视神经管处的视神经残端.然后,开眶顶,在显微镜下显露肿瘤,在眼球后极处切断视神经,将肿瘤切除,并电凝视神经的前后两残端.不必打开视神经管.通
This article reports on the experience of diagnosis and treatment of 63 cases of optic nerve meningioma associated with glioma from 1978 to 1986. These patients were affected by unilateral optic nerve involvement, not involving the optic chiasm. 28 of them were optic glioma (age was 14 to 56 years old, unilateral vision decreased from 0.5 to no light, more common in women.), 35 cases of optic nerve meningioma (age is 14 to 60 years old, unilateral vision decreased from 0.9 to no light, more common in females. ). Are using the forehead approach, but because the optic nerve gliomas mainly in the optic nerve sheath expansive growth, and meningioma is still infiltration of the adjacent structure. Therefore, the two are still different surgery. For the optic nerve glioma First, the intracranial tumor is removed together with the optic nerve, which is thickened between the optic chiasm and optic tract, and the bipolar electro-optic gazing at the optic nerve and the optic nerve stump at the optic canal. Then, the dome is opened and the tumor is exposed under the microscope. After the optic nerve is severed at the posterior pole, the tumor is resected and the optic nerves are electrocoagulated. There is no need to open the optic nerve tube.
