Functional outcome of endoscopic and external dacrocystorhinostomy in a teaching hospital

Arvind Varma, Sushobhan Dasgupta

Abstract


Background: The objective of the study was to compare & analyse the results of two different techniques of dacrocystorhinostomy (endonasal and external) in different etiological groups.

Methods: This prospective study was carried out for nasolacrimal duct obstruction from October 2016 to October 2018 who underwent dacrocystorhinostomy by two different methods. The patient was divided into two groups one who underwent endonasal DCR (n=55) and another group who underwent external DCR (n=55). In each group they were subdivided into 3 groups on the basis of aetiology into idiopathic, post traumatic and revision cases. The results were evaluated in follow up period of 6 months. At the end of the study, decoding of the groups was done and the results were analysed statistically, using Chi Square test and student t-test, using SSPS III software. P value of less than 0.05 was considered statistically significant.

Results: The success rate in endonasal DCR and external DCR was almost same in all the three groups (p>0.05).

Conclusions: This prospective study shows that both the methods have almost same success rate. This study also emphasises proper case selection and interdepartmental cooperation for optimum results.
