修复伴有泪小管断裂的眼睑裂伤时,应注意吻合断裂的泪小管,使泪道功能恢复。关于吻合时所用的管内留置物,归纳起来大致有铬制肠线、丝线、软性硅管、聚乙烯管、硬膜外麻醉用的尼龙管、弯形钝针头、不锈钢管等。这些材料对于吻合的效果和并发症各有其优缺点。我们1979～1986年,对16例泪小管断裂的患者,应用医用聚乙烯管进行了吻合术。随访结果:14例成功(87.5%),2例失败(12.5%)。现报道如下。 Repair with laceration of the canaliculus laceration, should pay attention to fracture of the lacrimal canaliculi, so that lacrimal duct function recovery. On the anastomosis used indwelling catheter, summed up roughly chromium gut, silk, soft silicone tube, polyethylene tube, epidural anesthesia nylon tube, curved blunt needle, stainless steel tube. These materials have their advantages and disadvantages for anastomotic effects and complications. We from 1979 to 1986, 16 cases of tear tube rupture, the use of medical polyethylene tube anastomosis. Follow-up results: 14 patients were successful (87.5%) and 2 patients failed (12.5%). Report as follows now.
