Curative effect and safety of modified dacryocystorhinostomy with simple anterior flap anastomosis in the treatment of chronic dacryocystitis

Abstract

AIM: To analyze the curative effect and safety of modified dacryocystorhinostomy with simple anterior flap anastomosis in the treatment of chronic dacryocystitis.METHODS: A total of 99 patients(113 affected eyes)with chronic dacryocystitis who underwent dacryocystorhinostomy in the hospital between March 2016 and July 2018 were enrolled in the retrospective study. They were divided into the traditional group(traditional dacryocystorhinostomy, 46 cases, 52 affected eyes)and the modified group(modified surgery with simple anterior flap anastomosis, 53 cases, 61 affected eyes)according to the surgical procedures. The surgical results, rates of granulation tissue formation around the anastomotic stoma at different time after surgery, rates of nasal mucosal epithelialization, size of the anastomotic stoma, the occurrence of surgical complications and the recurrence rate during 1a of follow-up were compared between the two groups.RESULTS: The grade of curative effect in the modified group was better than the traditional group(75.0% vs 95.1%)during 6mo of follow-up(PPvs 39.1%, Pvs 11.34±3.52mm2, Pvs 11.34±3.52mm2,PPCONCLUSION: The cure rate of patients undergoing modified dacryocystorhinostomy with simple anterior flap anastomosis is higher than those undergoing traditional surgery. The former can promote nasal mucosal epithelialization, maintain the size of anastomotic stoma and prevent the formation of surrounding granulation tissue. It is safe and effective, with few complications and low recurrence rate.
