泪道引流管在泪小管断裂吻合术中的应用

The lacrimal drainage tube assisted lacrimal canaliculus anastomosis for traumatic canaliculus laceration

目的观察泪道引流管在泪小管断裂吻合术中的应用价值。方法45例泪小管断裂以泪道引流管作为支撑物进行泪小管吻合（A组），与前一年在我院行硬膜外麻醉管为支撑的42例泪小管断裂吻合术作为对照组（B组），进行疗效比较。结果A组45例泪小管断裂，术后随访6个月治愈率为88．87％，B组42例N4,管断裂，术后随访6个月治愈率为66．67％。两组间治愈率比较差异具有统计学意义（χ^2=6．6285，P〈0．05），A组治愈率较高。结论泪道引流管是泪小管断裂吻合术中较好的支撑物，能增加患者术后的舒适度和延长戴管时间，从而提高手术成功率。

Objective To evaluate the lacrimal drainage tube assisted lacrimal canaliculus anastomosis for traumatic canalicular laceration. Methods 45 cases with traumatic canalicular laceration in group A, which the lacrimal drainage tube was used during repair of canalieular laceration. The effect was observed after withdrawal of the tube 3 - 4 months later. The results were compared with 42 cases of traumatic canalicular laceration with the epidural tube, which was used during repair of canalicular laceration （ group B ）. Results The lacrimal canalicular anastomosis in 44 cases were successful. The total cure rate was 88.87% in groop A, compared with 66.67% of that in group B （ postoperative follow - up 6 months）. There was a significant difference between the two groups （χ^2 = 6. 6285, P 〈 0.05 ）. Conclusion Lacrimal drainage tube maybe the optimal support in lacrimal canalicular anastomosis with higher comfort levels and increased treatment acceptance, thus raising the operational success rate.
