Comparison between Endoscopic and External Dacryocystorhinostomy by Using the Lacrimal Symptom Questionnaire: A Pilot Study

Abstract

Our study indicated that both endonasal and external DCR can lead to improvement in quality of life by using a validated questionnaire. Although there are differences in age and anatomic success rates between the two groups, subgroup analyses indicated that the differences in the Lac-Q scores persisted when age and anatomic patency were removed as potential confounding factors. Further larger, randomized studies would be helpful.
