【摘要】 目的 :观察经鼻外筛蝶窦径路行视神经减压术辅助药物治疗对外伤性视神经损伤的疗效。方法 :14例外伤性视神经损伤患者经鼻外筛蝶窦径路行视神经减压术的同时辅以大剂量激素及神经营养药物治疗。结果 :总有效率为 5 7.14% ,术中、术后无任何严重并发症 ;其中 2例伤后 8、11d手术 ,术后 6个月仍无光感。结论 :鼻外筛蝶窦径路行视神经减压术损伤较小 ,术野暴露充分 ,简易安全 ;同时辅以药物治疗 ,更有利于神经功能恢复。综合性治疗对外伤性失明患者是一种较好的措施。更多还原

【Abstract】 Objective:To observe the visual outcome of traumatic optic neuropathy treated with optic canal decompression surgery and medication.Method:15 patients, suffering from traumatic optic neuropathy, had received medication and optic canal decompression surgery through the approach of ethmoid and sphenoid sinus. The vision acuity was divided into 5 grades: no light perception, light perception, finger movement, counting fingers, vision≥ 0.1 , the vision acuity improvements reaching 2 grades or more were determined as effective.All patients were followed up for intervals of 1 month and 6 months.Result:The total efficient rate is 57.4 %, no intraoperative or postoperative complications were encountered.Being followed up 6 months, 2 cases, who underwent respectively the operation 8,11 days after trauma,felt no light perception.Conclusion:The approach through ethmoid and sphenoid sinus have the merits such as safety,less damage and larger operative field.Timely medication,megacorticosteroid therapy mainly,may play a good role in alleviating optic nerve edema and restoring its function.Comprehensive therapy may be an ideal treatment to traumatic optic neuropathy.更多还原
