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.
