摘要
目的 :探讨外伤性视神经损伤的手术时机与疗效的关系。方法 :经鼻外眶筛蝶窦进路显微视神经管减压术 9例 ;经鼻内窥镜筛蝶窦进路行视神经管减压术 14例 ,辅以大剂量皮质类固醇激素、能量合剂和神经营养药物。结果 :2 3例中有效 13例 ,视力平均提高 0 .2 33,无效 10例 ,有效率为 5 6 .5 %。 13例有效患者 ,其外伤至手术时间平均为 (2 .91± 1.87) d;10例无效患者 ,其外伤至手术时间平均为 (12 .90± 16 .77) d,两者相比较 ,其差异有极显著性意义 (P <0 .0 1)。8例外伤后眼球活动受限的患者 ,其中 7例恢复正常。结论 :外伤性视神经损伤在经过大剂量类固醇激素等治疗 48h无效者 ,应立即进行视神经管减压术 ,手术时机最好在外伤后 7d内进行。
Objective:To understand the relationship between the operative opportunity and effectiveness in the optic nerve injuries. Method:Twenty three cases with optic nerve injuries were undertaken optic canal decompression. Result:The visual acuity in 13 cases were improved after the operation, and progressed about 0.233 averagely. The average time from injuries to operations was ( 12.90 ± 16.77 ) d(3～22 d) in ineffective group.7 cases of hypoactivity of eyeball recovered in 8 cases.Conclusion:The optic nerve decompression should be done after the patients were treated with megadose of steroid for 48 hours and did not recover. The time had better be no more than 7 days.
