Abstract

Background: Dacrocystorhinostomy (DCR) is an operation used to treat nasolacrimal duct obstruction. Essentially there are two approaches: external and endoscopic. Several modalities are used in endoscopic DCR; all aiming to improve success rate, reduce complications, and shorten operative time. Both kerrison punch and drill are widely used in endoscopic DCR with non-conclusive knowledge about differences in operative details as well as on the outcome. The aim of this study is to compare between powered (drill) and non-powered (kerrison punch) DCR to clarify the superiority of one over the other. Methods: A retrospective chart review of 59 patients who underwent endoscopic DCR procedure at our institution from June 2013 until July 2014 (34 kerrison punch and 32 powered drill). Operative details, surgical outcome and complications were compared between both groups. Results: A total of 66 endoscopic DCRs were performed on 59 patients. Procedure success rate among kerrison punch group was 87.88 % vs. 90.9 % in powered drill group (p = 0.827), while complications for both groups were statistical not significant (p = 0.91). The mean operating time among kerrison punch group was significantly lower than in powered drill group (75 min vs. 125 min, p = 0.0001). Conclusion: Kerrison punch showed significant reduction in operating time when compared to powered drill for endoscopic DCR. No statistically significant difference was found between both groups regarding procedures' success rate and complication.
