目的 :探索治疗视神经外伤较好的手术方法和手术时机。方法 :开展了经鼻内窥镜视神经管减压术 ,并与鼻外进路进行比较。结果 :采用经鼻内窥镜鼻内进路视神经管减压术 5例 ,其中 3例视力由术前的无光感、光感恢复到术后 0 2～ 0 4,讨论了手术时机、手术进路的优点和不足、影响疗效的主要因素。结论 :认为经鼻内窥镜筛蝶窦进路视神经管减压术 ,出血少 ,有更大的实用性 ,是治疗视神经损伤较好的手术方法。视神经外伤后应行减压术 ,并越早越好。
Objective: To explore the treatment of optic nerve trauma better surgical methods and timing of surgery. Methods: Transnasal endoscopic optic canal decompression was performed and compared with the approach of the extranasal approach. Results: Transnasal endoscopic intranasal approach optic canal decompression in 5 cases, of which 3 cases of visual acuity by preoperative non-light feeling, light perception returned to postoperative 0 2 ~ 0 4, discussed the timing of surgery, surgery Advantages and disadvantages of the approach, the main factors affecting the efficacy. Conclusion: It is concluded that transnasal endoscopic screening of optic canal decompression of sphenoid sinus surgery, less bleeding, more practical, is a better surgical treatment of optic nerve injury. Decompression surgery should be performed after optic nerve trauma, and the sooner the better.
