A Comparison between External and Endonasal Dacryocystorhinostomy using the Lac-Q Questionnaire

Abstract

Abstract Purpose To assess lacrimal problems pre- and postoperatively with a symptom-based questionnaire (Lac-Q questionnaire), and to investigate patients’ satisfaction depending on their choice of surgical technique. Methods A total of 112 patients with lacrimal problems treated by external or endonasal dacryocystorhinostomy (DCR) were enrolled in the study. After surgery they were sent a symptom-based questionnaire (Lac-Q questionnaire) to evaluate their lacrimal symptoms pre- and postoperatively. Two complementary questions were added regarding the scar generated by the operation and their satisfaction with the operation. Results Pre-operative lacrimal problems, had high scores in the Lac-Q questionnaire. Patients expressed both symptomatic and social problems due to epiphora. The majority of the patients were satisfied after DCR surgery and no difference was found between the external DCR and endonasal DCR group concerning the degree of the patients’ satisfaction after the operation. A few patients were concerned about the scar after external DCR. Conclusion Lacrimal problems were regarded by the patients as a significant symptomatic and social burden. The relief of the symptoms and satisfaction after DCR operation were good regardless of the approach.
