Abstract：Objective To analyze the application effect of dacryocystorhinostomy under nasal endoscope in patients with chronic dacryocystitis. Methods A retrospective analysis was conducted on 68 patients with chronic dacryocystitis treated in our hospital from June 2017 to July 2019. They were divided into observation group and control group according to the choice of treatment selected by the patients or their family, 34 patients in each group. Patients in the control group were treated with lacrimal passage probing and lacrimal drainage tube implantation. In the observation group, they were treated with dacryocystorhinostomy under nasal endoscope. The total therapeutic effectiveness rate and postoperative complications were compared between the two groups. Results The total effective rate (94.12%) of the observation group was higher than that of the control group (76.47%), and the difference was statistically significant (P＜0.05). The overall incidence of complications in the observation group (5.88%) was lower than that in the control group(26.47%), and the difference was statistically significant (P＜0.05). Conclusion Treating chronic dacryocystitis with dacryocystorhinostomy under nasal endoscope has the advantages of mild injury, fast recovery, remarkable therapeutic effect and high safety. It has a high value of clinical application.
