Evaluation of the Role of Silicone Intubation in Non-complicated External Dacryocystorhinostomy

Abstract

Aim: Evaluation of the role of silicone intubation in non‐complicated External dacryocystorhinostomy (Ext‐DCR). Background: Silicone intubation is described as a step of Ext‐DCR. It was proposed that it may prevent obstruction involving the osteotomy or the common canaliculus. However, its necessity in non‐complicated Ext‐DCR is controversial. Objective: To study the effect of intubation and its duration on the results of non‐complicated Ext‐DCR. Methods: A prospective randomized interventional study that included 75 Ext‐DCRs. Patients with a high risk of failure were not included. Patients were randomly distributed between 3 equal groups with either traditional 3 months intubation (group A), short‐term intubation for 2‐3 weeks (group B), or non‐intubation (group C). Results: The success rate was 92%, 96%, and 92% in groups A, B, and C, respectively, with no significant differences (P = 0.853). Temporary foreign body sensation was reported in 16% in group A and 12% in group B. No significant complications were recorded in any of the 3 groups. Conclusion: Intubation (either short‐term or 3 months) did not affect the results of Ext‐DCR, which gives more evidence that it is not necessary in non‐complicated cases.
