新型泪道引流管治疗泪小管断裂30例

目的应用新型泪道引流管治疗泪小管断裂,恢复泪道引流通路。方法对30例泪小管断裂患者使用新型泪道引流管作为支撑管行泪小管吻合术,将引流的两端探子分别从上、下泪点插入泪道,通过泪管断端经过鼻泪管至下鼻道开口处,在鼻腔内窥镜直视下,用镊子触及并取出探子于鼻腔外,在探子与硅胶管交界处剪断硅胶管,两端硅胶管在鼻腔内打结留置于鼻腔。术后3月或0.5a拔管。并与以往用硬膜外麻醉管做支架的疗效进行比较。结果30例患者均于植管后3～7d内症状消失,29例拔管后达到治愈标准,无泪管豁开、下睑外翻或泪点外翻等并发症。治疗效果明显优于以硬膜外麻醉管作支架管吻合组。结论新型泪道引流管作为泪小管断裂吻合支撑管,伤口愈合快,成功率高,值得推广使用。

Modified drainage device for the treatment of 30 patients with canalicular laceration

Aim To find out the clinic value of a modified lacrimal drainage devi ce in reestablishing the lacrimal passage's continuity and eliminating abnormal tearing in canalicular laceration. Methods Thirty patients (21 males, 9 females , ranging in age from 2 to 56) with canalicular laceration were treated with the modified lacrimal drainage device. The probes of the device were inserted into the lacrimal passage respectively from the superior and inferior puncta under to pical anesthesia. Then both probes were extracted guided under the guidance of i ntranasal endoscope while the tube was left in the lacrimal passage for 3 to 6 m onths. Then the tube was removed. Results We compared the result of the modifie d device with that of the epidural catheter intubation. In the modified lacrimal drainage device group, symptoms of tearing disappeared within 3-7 days after su rgery in 30 patients; Tear drainage was recovered and epiphora was eliminated af ter the tube removal in 29 cases. No complications were observed. The success ra te was 96.7%. But in the control group, the success rate was 90% and complicatio ns occurred. Conclusion The new lacrimal drainage device is effective in the tre atment of canalicular laceration.
