蝶骨平面鞍结节区脑膜瘤多以视觉障碍发病,术后视觉恢复往往不理想。为提高手术疗效、本文分析了该部位脑膜瘤视觉损害的特征、手术方法的选择及术后效果。研究对象为8例患者,瘤蒂位于蝶骨平面3例,位于鞍结节5例。年龄26～68岁,平均54岁。男2例,女6例,首发症状均为视力视野损害,有6例患者视觉损害为唯一的神经症状。5例肿瘤位于中线,左右对称,均有轻度视力下降和不同程度的双颞侧偏盲,眼底均正常。3例肿瘤偏向一侧发展,患侧眼睛视力视野严重受损,2例有视神经萎缩。 5例肿瘤位于中线者,有4例较大,经双额什颅暴露肿瘤,先瘤内减压,再全切肿瘤,1例较小者取翼点入路全切肿瘤。5例患者视路损害以视交叉最明显,肿瘤未侵犯视神经管,术后视力视野改善,其中2例完
Sphenoid plane saddle nodular meningiomas and more to visual impairment, postoperative visual recovery is often not ideal. In order to improve the curative effect of the surgery, this article analyzes the characteristics of the visual impairment of the meningiomas in this area, the choice of surgical methods and the postoperative effects. The object of study was 8 patients. The tumor pedicle was located in the sphenoid plane in 3 cases and in the saddle nodule in 5 cases. Age 26 ~ 68 years old, average 54 years old. 2 males and 6 females, the first symptom was visual field damage, visual impairment in 6 patients as the only neurological symptoms. 5 cases of tumor located in the midline, left and right symmetry, both mild vision loss and varying degrees of bilateral temporal hemianopsia, fundus are normal. 3 cases of tumor development on one side, the affected side of the eyes seriously damaged visual acuity, optic nerve atrophy in 2 cases. 5 patients were located in the center of the line, there are 4 cases larger, double exposure of the skull to the tumor, the first tumor decompression, and then the total tumor, a case of smaller pterional approach to remove the tumor. Visual acuations were the most obvious in 5 patients, and the optic nerve tube was not infiltrated by the tumor. Visual acuity improved after operation
