不同入路视神经管减压开放术疗效分析

目的：对比分析不同入路视寞刘经管减压术的疗效。方法：比较1989年10月至2000年10月北京同仁医院收治178例进行不同入路视神经管减压术的患者的手术效果。结果：鼻外开筛视神经管减压开放术总有效率为64.5%，眶缘筛前-筛后入路视神经管减压开放术总有效率为63.0%。经颅视神经管减压开放术总有效率为78.0%。结论：经颅视神经管减压开放术，术野开阔，解剖清晰，可直接充分有效地开放视神经管骨壁，本术式疗效高，安全，有条件的地方应积极推广应用。

Analysis of the effectiveness of different approaches of decompression of optic canal

Objective:To analyse the effectiveness of different approaches of decompression of optic canal.Method:From Oct.1989 to Oct.2000,178 patients with traumatic optic canal fracture were admitted for decompression of the optic canal,using different approaches.The results were analysed.Result:The overall efficacy rates of decompression of optic canal via extranasal ethmoidotomy,the anterior and posterior ethmoid approach at orbital margin and transcranial decompression of optic canal were 64.5%,63% and 78% respectively.Conclusion:Transcranial decompression of optic canal has clear operating field,distinct anatomy and adequate decompression of optic canal with high efficiency,which can be applied in conditional hospitals.
