The purpose of this study was to compare the success rate of monocanalicular versus that of bicanalicular silicone intubations of the nasolacrimal duct for nasolacrimal duct stenosis (NLDS) in adults (patent nasolacrimal duct with resistance to positive-pressure irrigation).
In a prospective randomized clinical trial, 52 eyes of 38 patients with NLDS underwent either monocanalicular silicone intubation (MCI) (n = 26 eyes) or bicanalicular silicon intubation (BCI) (n = 26 eyes). All procedures were performed by 1 oculoplastic surgeon. Tube removal was planned for 3 months postoperatively. Treatment success was defined as the complete resolution of epiphora or intermittent epiphora with normal dye disappearance test at 6 months after tube removal.
The surgical outcome was assessed in 25 eyes with MCI and 21 eyes with BCI. The mean (SD) age of treatment was 52.7 (18.6) years for MCI and 49 (18.8) years for BCI. Treatment success was achieved in 19 of 25 eyes (76%) in the MCI group compared with 16 of 21 eyes (76.2%) in the BCI group. Differences between the 2 groups proved to be not significant (P = 0.9). The only complication was peripunctal pyogenic granuloma in 2 eyes with BCI.
Both MCI and BCI were successful in a similar percentage of patients with NLDS. The main advantages of the former technique were simple insertion and easy removal of the tube.
本研究旨在比较成人鼻泪管狭窄（NLDS）（鼻泪管通畅但正压冲洗有阻力）患者行单泪小管与双泪小管硅胶插管术的成功率。
在一项前瞻性随机临床试验中，38例NLDS患者的52只眼接受了单泪小管硅胶插管术（MCI）（n = 26只眼）或双泪小管硅胶插管术（BCI）（n = 26只眼）。所有手术均由1名眼整形医生完成。计划术后3个月拔管。治疗成功定义为拔管后6个月溢泪完全缓解或间歇性溢泪且染料清除试验正常。
对25只接受MCI的眼和21只接受BCI的眼进行了手术结果评估。MCI组治疗的平均（标准差）年龄为52.7（18.6）岁，BCI组为49（18.8）岁。MCI组25只眼中有19只（76%）治疗成功，BCI组21只眼中有16只（76.2%）治疗成功。两组之间的差异无统计学意义（P = 0.9）。唯一的并发症是2只接受BCI的眼中出现泪点周围化脓性肉芽肿。
MCI和BCI在NLDS患者中的成功率相似。前一种技术的主要优点是插管简单且拔管容易。
