Introduction: External dacryocystorhinostomy is a surgical procedure for the treatment of lacrimal drainage system disorders. Aim: To assess the usefulness of different silicone tubes in external dacryocystorhinostomy. Material and Methods: This study sampled 97 patients with lacrimal drainage system disorders who underwent the external dacryocystorhinostomy using two different silicone tubes. Forty one patients (Group A) underwent external dacryocystorhinostomy with silicone intubation using Nunchaku-style tubes, while in 56 patients (Group B) dacryocystorhinostomy was performed with O‘Donoghue silicone tubes. The data was analyzed using T-test, Chi-squared test and Fisher’s test. Results: The success rate was evaluated by achieved patency to irrigation and relief of epiphora. Patency in the group with Nunchaku-style tubes was 95.1% compared to 94.6% in the group with O‘Donoghue silicone tubes (p>0.05). Conclusion: Both tubes in external dacryocystorhinostomy were useful in the management of lacrimal drainage system disorders. Although it is easier and quicker to intubate and extubate Nunchaku-style tubes compared to O‘Donoghue silicone tubes, there was no statistically significant difference in success rate between the compared groups.
