Objectives: The objective of the study was to compare the outcome of Classical Dacrocystorhinostomy(DCR) alone or with Slicon intubation in patients of primary nasolacrimal duct obstruction.Study design: This is a randomized prospective interventional study performed at Saidu Teaching Hospitalform from 1st January'2006 to 31st December 2006.Material and methods: Diagnosis of nasolacrimal duct obstruction was made on basis of history, clinicalexamination, regurgitation test and syringing of the nasolacrimal passage. Patients were selected byconvenient sampling and were randomized to two groups, for DCR with and without Silicon tube. Silicontube was removed after 4 months of surgery. Patients were followed up to 6 months.Results: Total number of patients was one hundred. Fifty (50%) patients were operated with siliconintubation and 50 (50%) without silicon intubation. Male to female ratio was 1:1.27.Age range was 15 yearsto 80 years. Mean, median and mode ages were 42.54, 47 and 30 years respectively. Eleven patients werelost from the study at various stages and were not included in the results of the study. The complicationsnoted were silicon tube loss in 2 cases, silicon tube displacement in 3 cases and DCR failure in 4 cases.Among the failure, 2 cases belonged to each group with and without silicon intubation.Conclusions: We conclude that the complications rate with and without silicon intubation is the same inprimary nasolacrimal duct obstruction. It is therefore, recommended that silicon intubation may not benecessary in such cases.Key words: DCR, Intubation, NLD Obstruction.
