目的:观察改良硅胶管逆行置管治疗鼻泪管阻塞的临床疗效。方法:在门诊治疗的鼻泪管阻塞或合并慢性泪囊炎患者共68例74眼,在局部麻醉下行改良硅胶管逆行置管术,术后观察泪道通畅情况、溢泪现象、硅胶管位置及其洁净情况。结果:置管术后1wk泪道冲洗均通畅,拔管后1a总有效率为94.6%。结论:改良硅胶管逆行置管治疗鼻泪管阻塞操作安全、创伤小、时间短、出血少、疗效好。

AIM:To observe the treatment effectiveness of nasolacrimal duct obstruction by modified silicone tube retrograde intubation. METHODS:The outpatients diagnosed with nasolacrimal duct obstruction and chronic dacryocystitis were 68 cases (74 eyes).The procedure of retrograde intubation was performed in local anesthesia.The situation of lacrimal duct,epiphora, silicone tube location and cleanliness were observed after intubation. RESULTS:The lacrimal duct system was able to be irrigaetd one week after the operation. More than one year follow-up showed the cure rate was 94.6% after the removal of silicone tube. CONCLUSION:Modified silicone tube retrograde intubation for treatment of nasolacrimal duct obstruction is safe, minimally invasive, less time, less bleeding and good effect.
