COMPARISON OF OUTCOME FOLLOWING ENDOSCOPIC DACRYOCYSTORHINOSTOMY WITH EXTERNAL DACRYOCYSTORHINOSTOMY

Abstract

Objective:

To compare the outcome between endoscopic and external dacryocystorhinostomy.

Material & Methods:

A Retrospective study was conducted in the Department of ENT-HNS and Ophthalmology at Tribhuvan University Teaching Hospital, Kathmandu, Nepal for 2.5 years starting from Aug 2007 to Feb 2010. The endoscopic dacrocystorhinostomy was done under general anesthesia by the ENT faculty. External dacrocystorhinostomy was done by Ophthalmic surgeon under local anaesthesia. After surgery in both groups syringing of lacrimal duct was done twice in 1st, 2nd and 3rd week postoperatively. The outcome of surgery was categories as blocked and patent during the last syringing.

Results:

There were total of 59 dacrocystorhinostomy done in the period of 2.5 years. Among them 27 underwent endoscopic dacrocystorhinostomy (endo DCR) and 32 patients had external dacrocystorhinostomy. There were total 7 failure cases of dacrocystorhinostomy. Out of them 4 were after the endoscopic procedure and 3 were after external dacrocystorhinostomy. When statistical test was applied for the dacrocystorhinostomy by two different techniques, none of the data was found to be statistically significant.

Conclusion:

Endoscopic dacrocystorhinostomy  is comparable with external dacrocystorhinostomy regarding its outcome. However, a prospective study with larger sample size and long term follow up is required to observe the advantage of endoscopic dacrocystorhinostomy over external in the future.
