- Abstract: Objective To explore the efficacy of treating patients with endoscopic endonasal dacryocystorhinostomy(EE-DCR)failure by endoscopic endonasal common canaliculorhinostomy(EE-CAR),in order to improve the success rate of reoperation in patients with EE-DCR failure.Methods 44 cases(48 eyes)patients with EE-DCR failure caused by lacrimal sac nasal mucosal ostium atresia from April 2018 to January 2023 were enrolled.They were divided into two groups according to the principle of voluntariness before surgery.Group A(26 eyes)underwent EE-CAR,group B(22 eyes)underwent endoscopic endonasal ostial openning(EE-OO).The postoperative efficacy and complications of the two groups was compared.Results Followed up at 6 months postoperative,the success rate of surgery was 84.62％(22/26)in group A,which was higher than 54.55％(12/22)in group B.There was significant difference between the two groups(P＜0.05).Conclusions EE-CAR is better than EE-OO in the treatment of patients with small lacrimal sac remnant after EE-DCR due to ostium atresia.It is worthy for clinical application.
