Abstract

Objective: to evaluate the effect of silicone stent appliance in Dacryocystorhinostomy through comparing it with conventional Dacryocystorhinostomy. Materials and Methods: In this randomized clinical trial patients with Nasolacrimal duct obstruction attending to Otolaryngology clinic of Baqiyatallah hospital were randomly allocated to two groups regardless of age, gender and disease duration; group A patients underwent endoscopic Dacryocystorhinostomy (DCR) with silicon stent and group B patients underwent conventional endoscopic Dacryocystorhinostomy. Silicon stent was removed one month after intervention. Patients in both groups were evaluated for symptom resolution, peri-, and post-operational complications in first and sixth months after intervention. Results: Eventually 50 patients (32 female and 18 male) with Nasolacrimal duct obstruction underwent analysis in two groups; stent group with a mean age of 44.40 years and control group with a mean age of47.66 years. In a six-month follow-up, Epiphora was resolved in 24(96%) of patients in stent group and 22 (88%) of patients in control group (p=0.808). Also success rate of endoscopic DCR was not significantly different between two groups after six months of follow up (p=0.08). Conclusion: In conclusion applying silicon stent has no superiority to conventional DCR in terms of Epiphora resolution and post-operational complications. However further studies with a larger sample size are needed.
