我科于1983～1985年对泪道阻塞所致的流泪病人曾用泪道扩张术及泪道穿线术等治疗,收到一定的疗效。但对泪道阻塞较广泛者,愈后仍不理想,故又进一步用硬膜外麻醉塑料管置入泪道治疗泪道阻塞,此管为具有弹性硬韧的塑料管,直径0.8～1.2mm,管壁光滑可直接置于泪道内。术后形成通道较为宽敞,不易阻塞,我们认为效果满意。本治疗方法简便,术后无须特殊护理,故住院或门诊治疗均可。除急性泪囊炎及严重鼻病者禁用外,凡由泪道阻塞所致的流泪均可采用本术式治疗。手术方法简单,一般眼科医生
I Division in 1983 to 1985 lacrimal duct obstruction caused by tears patients had lacrimal duct dilatation and lacrimal duct threading and other treatment, received a certain effect. However, a more extensive lacrimal duct obstruction, the more the latter is still not ideal, so further use of epidural anesthesia plastic tube into the lacrimal duct lacrimal duct obstruction, this tube is flexible and tough plastic tube diameter 0.8 ~ 1.2mm , Smooth wall can be placed directly in the lacrimal duct. After the formation of a more spacious channel, not blocked, we think the results are satisfactory. The treatment is simple, no special care after surgery, so the hospital or out-patient treatment can be. In addition to acute dacryocystitis and severe rhinitis disabled, all tears caused by lacrimal duct tears can be treated with this technique. The surgical method is simple, the general ophthalmologist
