Abstract

PURPOSE: This study is to evaluate the effectiveness on patency rates of two silicone tube intubation comparing with one silicone tube intubation in endonasal dacryorhinostomy.
METHODS
The 99 patients' charts were reviewed on patency rate and the cause of failure in patients with nasolacrimal duct obstruction, who had undergone endonasal DCR with two sets of silicone tube intubation. Another 100 patients who underwent endoscopic DCR with single silicone tube intubation, were enrolled in this study as the control group to compare the patency rates and the causes of failure between the two groups.
RESULTS
Double silicone tube intubation group showed much higher lacrimal patency rates (89.9%) than that (84.0%) of single silicone intubation group. It seems to be due to less membrane formation (4%) at the site of internal ostium by sufficient bougination in two silicone tube intubation group compared with one silicone tube intubation group (16%). Two silicone tube intubation in endonasal DCR was more effective in preserving the lacrimal patency and avoidance of membranous obstruction at newly created nasal ostium (P=0.03). There were no significant differences in the size of nasal cavity, sex and age distributions, and postoperative cares between the two groups.
CONCLUSIONS
Two silicone tube intubation can be considered to be a method of improving success rate in endonasal DCR.
