额-眶-蝶骨纤维结构不良的经颅视神经减压术

为探讨因额 眶 蝶骨纤维结构不良致视力进行性下降经颅做视神经减压术的临床效果 ,作者对收治的 2 5例次患者进行了回顾性研究。结果显示 ,术后 1周 ,2 1例次患侧眼视力改善和稳定 ,4例次视力减退。视力减退的 4例次中有 3例次患侧眼术前视力接近失明。18例次获得有效随访 ,随访时间 2～2 2年 ,平均 6年 ,视力再减退的仅 3例次。研究结果表明 ,经颅做视神经减压术挽救视力是额 眶 蝶骨纤维结构不良致视力进行性下降的有效的手术治疗方法 ,但术前视力接近失明的患者手术效果不理想

TRANSCRANIAL OPTIC NERVE DECOMPRESSION FOR FRONTO-ORBITO-SPHENOIDAL FIBROUS DYSPLASIA

To evaluate clinical effect of transcranial optic nerve decompression on fronto orbito sphenoidal fibrous dysplasia with progressive vision loss, 25 cases were studied retrospectively. All patients had undergone transcranial optic nerve decompression. One week after operation, 21 patients experienced improvement or stability in vision, but 4 patients complained reduction in vision. Before operation, the vision of the affected eye was near blindness in 3 cases among the 4 cases who failed to gain improvement in vision after operation. Effective follow up was achieved in 18 cases, and the follow up period was from two to twenty two years (average six years). Among them, only 3 paticnts showed recurrence of visual disturbance. The results showed that transcranial optic nerve decompression was effective in rescuing vision in fronto orbito sphenoidal fibrous dysplasia with progressive vision loss. Once the patient was near blind before the operation, the surgical result was unsatisfactory.
