目的评价外伤性泪小管断裂吻合术疗效。方法在手术显微镜下寻找到泪小管断端后插入硬膜外麻醉聚乙烯管做支撑物,然后断端用8-0缝线对接缝合3￣4针。结果59例都能在手术显微镜下成功找到泪小管的两断端。痊愈37例(62.2%),好转19例(32.2%),无效3例(5.6%)。结论用硬膜外麻醉聚乙烯管做支撑物,行泪小管断端吻合手术,疗效确切、经济。 Objective To evaluate the effect of traumatic rupture and anastomosis of tracheobronchial tubes. Methods Under surgical microscope to find the end of the canalicular end of the insertion of epidural anesthesia polyethylene tube as a support, and then stitched with 8-0 suture stitching 3 ~ 4 stitches. Results 59 cases were able to successfully find the two ends of the canaliculi under the surgical microscope. Thirty-seven cases (62.2%) were cured, 19 cases (32.2%) were improved, and 3 cases (5.6%) were ineffective. Conclusion Epidural anesthesia polyethylene tube as a support, the end of canalicolalic anastomosis surgery, curative effect is accurate and economical.
