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.
Highlights
External dacryocystorhinostomy (Ext-DCR), since it was first described in 1904, has been well known as the operation of choice for the management of Nasolacrimal Duct Obstruction (NLDO)

Controversy exists about the necessity of intubation in Ext-DCR surgeries done for acquired NLDO
Summary
External dacryocystorhinostomy (Ext-DCR), since it was first described in 1904, has been well known as the operation of choice for the management of Nasolacrimal Duct Obstruction (NLDO). It helps in tear drainage by communicating the lacrimal sac and nasal mucosa through an ostium in the lacrimal bone [1, 2]. It was proposed that intubation may prevent obstruction involving the osteotomy or the common canaliculus [3 - 5]. 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. Its necessity in non-complicated Ext-DCR is controversial
