摘要
目的探讨外伤性视神经损伤的诊断与影像学特点以及显微手术在经颅视神经管减压中的应用和效果。方法总结经颅显微手术视神经管减压治疗外伤性视神经损伤患者17例,分析患者视神经管骨折情况,随访术后6个月的视力变化。结果受伤至减压手术时间为4 h至7 d,显微手术采用翼点入路11例,额下入路4例,眶上锁孔入路2例。术后6个月随访视力改善的总有效率为82.3%,无严重术后并发症。结论经颅显微视神经管减压术对外伤性视神经损伤有较好的疗效,视神经骨性管道充分开放及神经鞘膜的减张可使受伤视神经得到充分减压,从而避免继发性的损害。
Objective To investigate the diagnosis and imaging feature of traumatic optic nerve injury, and to investigate the effect of microsurgery on optic nerve injury. Method Seventeen patients with optic nerve injury were retrospectively analyzed who treated with microsurgery of optic canal decompression with transcranial approach. The time from injury to surgery, the fracture of optic nerve canal, the change of optic nerve after injury was observed. The change of visual acuity before operation and 6-month following-up after operation was also observed . Results The incidence of fracture of optic nerve canal was 100%. The time from injury to surgery was 4 hours to 7 days. Three methods were used： 11 patients were performed with pterional approach, 4 with subfrontal approach, and 2 with supraorbital burr hole approach. Visual acuity was improved at 6 months after operation, and there was no severe complication. Conclusions Optic canal decompression with transcranial approach is effective for traumatic optic nerve injury. It is useful for injured optic nerve to decompress adequately and to avoid secondary damage.
