Dacryocystorhinostomy (DCR) is a procedure of choice for nasolacrimal duct obstruction and chronic dacryostenosis in the setting of patent canaliculi and a functional lacrimal pump. Two major approaches are utilized: external, via a transcutaneous incision and endonasal endoscopically guided. The surgery has a high success rate via both approaches. We review the history, evolution, current techniques, complications and future directions of DCR.
