目的:探讨视神经管减压术治疗外伤性视力障碍的有效方法。方法:采用鼻内镜下视神经减压术治疗外伤性视力障碍患者14例。结果:随访3～18个月,其中8例有不同程度视力改善,6例无效。术后全部患者术腔上皮化,无并发症发生。结论:经鼻内镜筛蝶窦入路视神经减压术损伤较小、疗效确切,且不遗留面部瘢痕,容易为患者所接受。对伤后数天至1个月、大剂量激素治疗无效、视力损伤严重的患者,手术仍有可能挽救视力。
Objective: To explore the effective method of optic canal decompression in the treatment of traumatic visual impairment. Methods: 14 cases of traumatic visual impairment were treated by endoscopic optic nerve decompression. Results: All the patients were followed up for 3 to 18 months, of which 8 had different degrees of visual acuity improvement, 6 were ineffective. All patients with postoperative epithelialization, no complications. Conclusion: Transnasal endoscopic screening of sphenoid sinus optic nerve decompression lesion less effective, curative effect, and does not leave facial scars, easy for patients to accept. On the days after injury to 1 month, high-dose hormone therapy is invalid, severe visual impairment in patients with surgery is still possible to save eyesight.
