Abstract

Background Endoscopic dacryocystorhinostomy (Endo-DCR) is an operation aimed to treat chronic epiphora. Failure of Endo-DCR is defined as the recurrence of epiphora with complete obstruction of the neo-stoma. Several adjunctive techniques were prescribed to improve the outcomes of Endo-DCR one of them is the preservation of nasal mucosal and lacrimal flaps, thus this study was designed to compare the outcome of Endo-DCR in non-preserved and preserved flaps techniques. In addition to the evaluation of factors that may affect the outcomes of Endo-DCR. Patients and methods This retrospective study was done on 60 patients whom underwent 63 Endo-DCR procedures (3 of them bilaterally) at our hospital between 2015 and 2023. The patients were divided into 2 groups. Group A underwent non-preserved flaps technique (28 cases) and group B underwent preserved flaps technique Endo-DCR (35 cases). Results Successful rate was 82.14% in group A and 91.48% in group B. Failure was found in 5 cases (17.86 %) in group A and in 3 cases (8.57%) in group B presented by recurrent epiphora with non-visualized neo-stoma by endoscope. Conclusion Endo-DCR technique with preserved nasal mucosal and lacrimal flaps helped decrease the rate of closure of neo-stoma by decreasing the rate of granulation tissue formation as well as improving the success rate in comparison with non-preserved flaps technique without statistically significant difference.
