Assessment of the Rule of Intubation on the Outcome of External Dacryocystorhinostomy

Abstract
Background: Dacryocystorhinostomy (DCR) surgery through an external approach has been the gold standard for the treatment of nasolacrimal duct obstruction. The question whether to use silicone tube or not.
Aim of Study: The aim of this study was to evaluate the rule of bicanalicular intubation in the success rate of external DCR. This study was to evaluate the effect of intubation on the outcome of external dacryocystorhinostomy.
Patients and Methods: It was a prospective interventional randomized study that was carried on 45 eyes of patients had done DCR. All operations were done under general anathesia and they were divided into 3 groups as follow:
1-Group (A): 15 patient had done DCR with long term intubation (12 weeks).
2-Group (B): 15 patient had done DCR with short term intubation (2 weeks).
3-Group (C): 15 patient had done DCR with no intubation.
Results: There is no significant difference between the use of intubation or not in cases of acquired NLDO and chronic dacryosistitis.
Conclusion: External dacryocystorhinostomy is still the gold standard surgical treatment in primary nasolacrimal duct obstruction. This study shows that the silicone tube implanta-tion is not necessary in the surgery.
