泪小管断裂是比较常见的眼外伤疾病。但由于泪小管管径很细,生理状态下直径不足1mm,断裂后裂伤组织内不易找到断端,吻合则更为困难。我科自1989～1990年共收治了8例下泪小管断裂的患者,其中1例伴有泪囊部贯通伤,经采用硬膜外麻醉管做支撑物,吻合泪小管后效果良好,现报告如下。 Tear tubule rupture is a more common ocular trauma disease. However, due to the very small diameter of the canaliculus, less than 1mm in diameter under physiological conditions, it is not easy to find the stump in the lesion after fracture, and anastomosis is even more difficult. Our department from 1989 to 1990 were treated in 8 cases of lacrimal canaliculi in patients with rupture, including 1 case of penetrating dacryocyst injuries, the use of epidural anesthesia tube as a supporter, the effect of good agreement after lacrimal duct, the report is now as follows.
