目的:探讨经颅显微视神经减压术治疗创伤性视神经损伤的疗效及与颅外入路减压术相比之优点。方法:回顾性分析了12例经颅显微视神经管减压手术患者的临床特点和治疗效果,并复习近期颅外入路视神经减压术的相关文献就疗效进行对比。结果:全部患者术后随访3～12mo,手术有效率达83%,无术后脑脊液鼻漏等发生。结论:创伤性视神经损伤的减压手术效果肯定,宜在伤后尽早实施。经颅入路管内段视神经减压术比颅外入路更具优越性,应列为首选。

AIM:To explore the therapeutic effects of microsurgical decompression of traumatic optic nerve neuropathy via transcranial approach,in comparison of extracranial approach.METHODS:A total of 12 cases with optic nerve neuropathy which underwent microsurgical decompression via transcranial approach were retrospectively analyzed,and the clinical characteristics and methods of the therapy were concluded.The recent literatures on surgical decompression of optic nerve neuropathy via extracranial approach were reviewed and the therapeutic effects of such an extracranial approach were compared with our transcranial approach.RESULTS:All patients were followed up for 3 to 12 months postoperatively,with an average rate of efficacy being 83 percent.No patient experienced cerebrospinal fluid leakage after surgery.CONCLUSION:The efficacy of decompression of optic nerve neuropathy through the optic canal is concluded and the surgery should be performed as early as possible.Because of the better therapeutic effects,decompression of optic nerve neuropathy via transcranial approach is superior to that via extracranial approach.
