摘要
目的探讨鼻内镜下视神经管段的解剖及临床应用,进而了解蝶筛区域的解剖结构。方法经鼻内镜下对15具湿性成人尸头30侧筛、蝶窦解剖,观察筛蝶区域的解剖结构,对视神经骨管段进行观察和测量。对6例损伤性视神经病变患者的诊疗进行回顾性研究。结果视神经管眶口与鼻小柱和鼻翼交界处左侧的距离为(77.90±1.65)mm,74.8～81.0mm,右侧为(77.65±1.77)mm,74.2～80.8mm;视神经管颅口与鼻小柱和鼻翼交界处左侧的距离分别为(83.80±2.14)mm,80.2～86.8mm,右侧为(83.38±2.36)mm,79.4～86.4mm;经鼻内镜视神经管减压术(transethmoidalopticnervedecompression,TOND)治疗6例损伤性视神经病变(trau-maticopticneuropathy,TON),4例效果良好。结论临床手术中OC的准确定位具有重要意义;TOND是治疗TON较好的办法。
[Objective] To provide objective data for the location of the optic canal in ethmoidectomy. [Methotis] 30 temporal ethmoidals in 15 cadavers were dissected endoscopically. The optic nerves were observed and measured. 6 cases of traumatic optic neuropathy were studied in retrospect. [Result] The median distance between the joint of columella nasi and alae nasi and the eye socket meatus of optic canal was （77.90±1.65） range （74.8 ± 81.0） mm on the left side and （77.65±1.77） range （74.2-80.8） mm on the fight side; the encephahc meatus of optic canal was （83.80±2.14） to （80.2±86.8） mm on the left side and （83.38±2.36） to （79.4-86.4） mm on the fight side. 6 cases of patients with traumatic optic neuropathy （TON） were combined treated, visual acuity in 4 of 6 patients was improved. [Conclusion] Endoscopic localization of the optie nerve is of vital importance in ethmoidectomy. Transethmoidal optic nerve decompression is one favorable therapy to traumatic optic neuropathy.
