ABSTRACT

Purpose: To study the result of silicone tube insertion in external dacryocystorhinostomy (DCR). Methods: During external DCR for primary nasolacrimal duct obstruction carried out between january 2013 to february 2015. A total 60 patients with primary nasolacrimal duct obstruction were taken for DCR surgery. The patency of lacrimal drainage system was evaluated with lacrimal syringing. Silicone tube intubation was added to surgery in 30 consecutive patients and was not used in 30 consecutive patients. Lacrimal syringing in the third month were recorded. Surgical success was accepted as the patency of the formed ostium with lacrimal syringing. Results: Success rate was 90% (27/30) in patients with silicone intubation, and 86.67% (26/30) in without intubation. The difference between the groups was not found as statistically significant (p>0.05). Cases in which intubation was avoided had a large lacrimal sac and a wide nasal cavity. Conclusion: This study shows that the silicone tube implantation is not necessary in the surgery. External DCR with silicone intubation is safe and effective surgery in patients whom we expect less favourable outcome. The complications associated with silicone intubation are negligible.
