泪小管断裂吻合术

Anastomosis of Broken Lacrimal Canaliculus

探讨寻找泪小管断端方法 ,提高吻合泪小管成功率。从上泪小点注入带有 8/ 0尼龙线的粘弹剂 ,在显微镜下辨认粘弹剂的出口及找到尼龙线 ,再用尼龙线引套较粗丝线 ,硅胶管使泪小管断端紧密结合愈合。11例下泪小管断裂患者接受手术后 8例成功。使用从泪小点注入带线粘弹剂手术方法能迅速、准确找到泪小管断端并使硅胶管容易套入 ,使泪小管吻合术操作更为简单且更容易成功。

In order to improve the successful rate of anastomosis of broken lacrimal canaliculus, a new method of searching the broken ends of lacrimal canaliculus was developed. The viscoelasticity containing 8/0 nylon thread was injected into the broken lacrimal canaliculus from the upper lacrimal point. The outflow of viscoelasticity under microscopy was discriminated and the nylon thread found. A silk thread sutured with silicone tube was introduced from the broken end by the nylon thread. Then the two broken ends of lacrimal canaliculus were sutured compactly. Of the 11 patients with broken lacrimal canaliculus undergoing operation 8 patients succeeded. Using the method, the broken ends of lacrimal canaliculus can be found fast and accurately and the silicone tube easily introduced.
