To compare the success rate of monocanalicular versus pushed monocanalicular silicone intubation (PMCI) of the nasolacrimal duct for congenital nasolacrimal duct obstruction (CNLDO).
In a prospective randomized clinical trial 53 eyes of 49 patients with CNLDO underwent either monocanalicular silicone intubation (MCI) (n=28 eyes) or PMCI (n=25 eyes). All procedures were performed by 1 oculoplastic surgeon. Treatment success was defined as the complete resolution of epiphora at 3mo after tube removal.
The surgical outcome was assessed in 20 eyes with MCI and 20 eyes with PMCI. The mean age of treatment was 26.25±10.08mo (range, 13-49mo) for MCI and 26.85±12.25mo (range, 16-68mo) for PMCI. Treatment success was achieved in 18 of 20 eyes (90.0%) in the MCI group compared with 10 of 20 eyes (50%) in the PMCI group (P=0.01). In the PMCI group, the tube loss (30%) was greater than the MCI group (5%), however the differences between the 2 groups proved to be not significant (P=0.91).
Our results indicate that MCI has higher success rate in CNLDO treatment compared with PMCI in this small series of patients.
比较鼻泪管单管硅胶插管术与推注式鼻泪管单管硅胶插管术（PMCI）治疗先天性鼻泪管阻塞（CNLDO）的成功率。
在一项前瞻性随机临床试验中，49例患有CNLDO的患者的53只眼接受了单管硅胶插管术（MCI）（n = 28只眼）或推注式鼻泪管单管硅胶插管术（PMCI）（n = 25只眼）。所有手术均由1名眼科整形外科医生完成。治疗成功定义为拔管后3个月溢泪完全消失。
对20只接受MCI治疗的眼和20只接受PMCI治疗的眼进行了手术结果评估。MCI组的平均治疗年龄为26.25±10.08个月（范围13 - 49个月），PMCI组为26.85±12.25个月（范围16 - 68个月）。MCI组20只眼中有18只（90.0%）治疗成功，而PMCI组20只眼中有10只（50%）治疗成功（P = 0.01）。在PMCI组中，导管丢失率（30%）高于MCI组（5%），然而两组之间的差异无统计学意义（P = 0.91）。
我们的结果表明，在这一小系列患者中，与PMCI相比，MCI治疗CNLDO的成功率更高。
