Abstract

Background: Dacryocystorhinostomy (DCR) is one of the most common oculoplastic surgeries. In this study, we aimed to compare single and double flap anastomosis results in external dacryocystorhinostomy surgery.
Materials and Methods: Between January 2016 and November 2017, 156 patients who underwent external DCR were evaluated retrospectively. All cases were performed under general anesthesia. In the first group, 86 patients (52 female, 34 male) had a double flap external DCR. In the second group, 70 patients (40 female, 30 male) had a single flap external DCR.
Results: The mean follow-up period was 18.2±8.6 months in the double flap group and 16.4±5.4 months in the single flap group. The mean age was 48.2±16 in the double flap group and 46.3±17 in the single flap group. The success rate was 96.6% in the double flap group and 95.8% in the single flap group.
Conclusion: In our study, there was no difference in surgical success in patients undergoing single and double flap external DCR surgery.
