Abstract
Background and Objectives: Primary acquired obstruction of Nasolacrimal duct is the most common cause of Tearing in adults requiring surgery. The aim of this research is evaluating the results of external dacryocystorhinostomy with and without silicone intubation in NLDO.
Materials and Methods: This randomized clinical trial study was done on 80 patients with nasolacrimal duct obstruction. These were divided into two groups of Ex.DCR with and without silicone intubution incidentally.
Results: Overall success rate were 77.5% in Ex.DCR and 90% in Ex.DCR with silicone intubation(p<0.05)
Conclusion: Ex.DCR with silicone intubution is a procedure with more successful results comparing the other method. This can be advised as routin procedure for the management of nasolacrimal duct obstruction.
