The success rate of EL-DCR was lower than that of the external DCR; however, no statistically significant difference was observed. Endoscopic transcanalicular diode laser DCR may be considered as an alternative method to external DCR with these results.
145higher difference, no statistically significant difference was determined by Yates' corrected chi-square test (p = 0.202). We also thought there might be a higher clinical difference with these results, but no statistically difference was found. We agree with the Dr. Javed Ali about small sample size that may be considered as a limitation of our article.In this study, we also recommended careful selection of EL-DCR cases for nasal pathologies. Nasal pathologies may be a handicap to perform the operation and may cause failure postoperatively. 2,3 In unsuccessful EL-DCR patients, we found several nasal pathologies that may cause failure; however, major nasal pathology was not found in the unsuccessful Ex-DCR patients, which may affect the operation negatively. In particular, we emphasized the importance of nasal anatomy in EL-DCR more than Ex-DCR.As reported by Henson et al., 4 we considered that reduction of laser energy and prevention of scar or granulation tissue formation with mitomycin C application around the bone ostium would influence the success of EL-DCR positively in future. We hope, our explanations are satisfactory for the related authors. We also congratulate Dr. Javed Ali for enriching the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
