目的:评价外伤性泪小管断裂显微吻合手术的效果。方法:显微镜直视下寻找鼻侧泪小管断端,以硬膜外麻醉导管为支撑的吻合方法治疗泪小管断裂87例,置管2～3mo。拔管后随访3～24mo。结果:82例随访,68例泪道冲洗通畅,无泪溢;8例冲洗泪道通畅,有泪溢;6例通而不畅。结论:以硬膜外导管为支撑,显微镜直视下寻找泪小管鼻侧断端,治疗外伤性泪小管断裂效果满意。

AIM:To evaluate the effect of microscopic anastomosis for traumatic canalicular.·METHODS:Totally 87 patients with traumatic canalicular were found the nasal lacrimal duct stump under the microscope,and they underwent microscopic anastomosis surgery by epidural catheter. After that,epidural catheter tube were detained about 2-3 months and follow-up time were 3-24 months after operation.·RESULTS:Lacrimal patency without epiphora were occurred in 68 patients after extubation; unobstructed lacrimal irrigation with epiphora in 8 cases and stenosis in 6 cases. ·CONCLUSION:Microscopic anastomosis by the epidural catheter frame is an ideal method for traumatic canalicular.
