Dacryocystorhinostomy (DCR) is the treatment of choice for epiphora due to nasolacrimal duct obstruction. A passage is created between the lacrimal sac and nasal cavity by removing the layers of bone and mucosa between them. It can be performed via an external (transcutaneous) or endonasal route with equivalent success rates.[1] In order to prevent restenosis of the ostium, silicone tubes are often used to maintain the patency of the newly-created fistula. The tubes are removed between 6 weeks and 3 months post-operatively.
