Surgical Outcomes of Primary and Revision Endoscopic Dacryocystorhinostomy

Objective: In the current study, whereas the results of endoscopic primary and revision endoscopic dacryocystorhinostomies (END-DCR) were evaluated, the success rates in patients who did or did not undergo nasal surgery were also compared. Methods: A retrospective medical record review of 70 patients (with a total of 72 affected cases) who were admitted to our clinic with a primary complaint of epiphora between January 2002 and July 2009 was performed. Patients who required additional nasal procedures were also included in the analysis. A successful DCR was defined as relief of symptoms on testing with irrigation at the last follow-up visit. Results: The success rates were 82.1% (23/28 DCRs) in the primary END-DCR group and 84.1% (37/44 DCRs) in the revision END-DCR group. There were no significant differences between the groups regarding overall surgical success rates (P = 0.829). The need for additional nasal surgery was significantly higher in the revision cases (52.3%) than the primary cases (28.6%; P = 0.048). No significant difference regarding success rates existed between the patients who required an additional septoplasty or ancillary sinus surgery and the patients who did not have nasal pathology and underwent END-DCR alone (P = 0.456). The mean follow-up period was 11 months in the revision END-DCR group and 8 months in the primary END-DCR group. Conclusions: Endoscopic DCR should be considered as the treatment of choice in cases with intranasal pathologies. Endoscopic DCR is a safe and effective procedure in revision cases, as well as in primary cases.
