Abstract

Purpose
To analyze the results of secondary silicone tube insertion in patients exhibiting persistent epiphora despite acquiringanatomical patency after primary endonasal dacryocystorhinostomy.
Methods
We conducted a retrospective review of 23 patients (37 eyes) seen at our department from December 2006 to April2018 for primary endonasal dacryocystorhinostomy. These patients exhibited anatomical patency but experienced persistentepiphora, requiring secondary silicone tube re-insertion.
Results
The average age at reintubation with a silicone tube was 59.8 years, and the average follow-up was 14.8 months. Theinterval between the primary endonasal dacryocystorhinostomy and secondary silicone tube re-insertion was approximately24.5 months. The silicone tube re-insertion, was successful for 33 of 37 eyes with four eyes exhibiting partial improvement. Thus,there were no failed outcomes based on subjective symptoms.
Conclusions
After primary endonasal dacryocystorhinostomy, when tearing symptoms persist despite no evidence of anatomicalproblems, our results show that secondary silicone tube re-insertion is a safe and effective procedure for patients experiencingfunctional failure.
