Abstract Purpose Silicone stent intubation is used in DCR procedures to prevent a restenosis of the surgical ostium. However, use is not generally accepted due to concers on cost/effectiveness. The goal of our study was to analyze the types and rate of complications associated with monocanalicular and bicanalicular silicones stent intubation nad success rate of DCR procedure. Methods A consecutive series of 114 patients who underwent 120 DCR procedures at our institution from November 2005 on has been included in the study. All DCR (transcanalicular laser DCR’s) procedures were performed under general anaesthesia. One of two types of silicone intubation was inserted at each procedure: bicanalicular silicone stent (72 cases), and inferior monocanalicular stent alone (38 cases). In the former a metallic clip was used to secure the stents in the nasal cavity, in the latter a double knot was applied. The intubation has been removed after 4 months. Results We encountered the following complications: cheese‐wiring of lacrimal punctum (14 cases), prolaps of intubation at the punctual side (9 cases), irritation of conjunctiva (3 cases), corneal erosion (1 case), retention of metallic clip in lacrimal sac (1 case). We statistically analyzed and compared the rate of complications for both types of intubation. Decubitus of the lacrimal punctum was less frequent with monocanalicular intubation compared to bicanalicular intubation; other complications were present at similar rates. Conclusion Complications with silicone stent intubation are not difficult to cope with and normally do not produce adverse effect on DCR success rate with the exception of early and complete prolaps of intubation, which is associated with a lesser success rate of DCR.
