Endoscopic Dacryocystorhinostomy With Ologen Implant

Abstract

Objective: To compare the effectiveness of endoscopic dacryocystorhinostomy with ologen implant versus endoscopic dacryocystorhinostomy with silicon tube implantation.Background: Chronic dacryocystitis is an inflammatory disorder of the lacrimal sac that is mostly accompanied by partial or total nasolacrimal duct obstruction. Watering and discharge are the most common symptoms, however some cases can escalate to serious ocular and extraocular complications. It can result in severe ocular morbidity and loss of productivity at work, as it can temporarily obscure vision, prevent a person from concentrating on their task, and be socially uncomfortable. The goal of this research is to find a way to reduce recurrence after DCR surgery.Methods: We conducted a prospective controlled study to evaluate effectiveness of endoscopic dacryocystorhinostomy with ologen implant versus endoscopic dacryocystorhinostomy with silicon tube implantation. A total of 40 patients underwent primary endoscopic DCR surgery in Menoufia University Hospital from march 2020 till march 2021. A total of 20 cases did endoscopic DCR using ologen implant (group A) and the other 20 cases did endoscopic DCR using silicon tube (group B). Results: The success rate, which was evaluated by MUNK score and syringing test, was compared between both groups also rate of complications like epistaxis, implant complications and post surgery synechiae was compared. Success rates was 75% in ologen group and 85%in the other group. Epistaxis, infection and post sugery synechiae were statistically in significant between the two groups but implant complications was more in ologen group than the other group.Conclusion: Endoscopic DCR with ologen implantation is not superior to endoscopic DCR with silicon stenting due to the challenging ologen implantation procedure and the high cost relative to silicon stenting.
