Abstract

Background Chronic dacryocystitis is an inflammatory disorder of the lacrimal sac that is accompanied by nasolacrimal-duct obstruction. Watering and discharge are the most common symptoms. Objectives To compare the effectiveness of endoscopic dacryocystorhinostomy (DCR) with ologen implant versus endoscopic DCR with silicone-tube implantation. Patients and methods A prospective comparative study was conducted to evaluate the effectiveness of endoscopic DCR with ologen implant versus endoscopic DCR with silicone-tube implantation. A total of 40 patients underwent primary endoscopic DCR surgery from March 2020 to March 2021. A total of 20 cases underwent endoscopic DCR using ologen implant (group A) and the other 20 cases underwent endoscopic DCR using silicone tube (group B). Results The success rate, which was evaluated by MUNK score and syringing test, was compared between both groups, also, rate the complications like epistaxis, implant complications, and postsurgery synechiae was compared. A success rate was 75% in ologen group and 85% in the other group. Epistaxis, infection, and postsurgery synechiae were statistically insignificant between the two groups, but implant complications were more in ologen group than the other group. Conclusion Endoscopic DCR with ologen implantation is not superior to endoscopic DCR with silicone stenting due to difficult fixation of ologen in lacrimal fossa, more complications, and the high cost relative to silicone stenting.
