Background and Objectives: External DCR is an effective and common surgical approach in treating nasolacrimal duct obstruction. To investigate the relation between the times of silicone tube removal after external dacryocystorhinostomy, related factors and success rate of surgery. Method: In a retrospective study, 168 patients with primary nasolacrimal duct obstruction (NLDO) which underwent dacryocystorhinostomy (DCR) with intubation were evaluated. Demographic information including age, gender, time of silicone tube remaining in the NLD, follow up period and result of the operation were recorded. The result of the surgery in first group (patients with tubes being lost before the planned time) and second group (patients with tubes being removed after the planned time) were extracted and compared. Failure of surgery was defined as symptomatic epiphoria or infection in follow up period. Results: From 168 patients with complete follow up in17 cases tube was extruded or had to be removed before planned 3 month period. Success rate was 82.3% in first group and 92.1% in second group. There was no significant difference statistically between two groups (P=0.18). 3 people the mentioned 17 patients who were lost their tube earlier had undergone reoperation. Conclusion: This study shows that the time of silicone tube removal has no effect on success rate of surgery. Endoscopic evaluation of osteotomy site regarding obstruction occurrence are suggested to estimate the appropriate time of silicone tube removal.
