A retrospective study to compare outcomes after external dacryocystorhinostomy (Ex-DCR) and trartsnasal endoscopic assisted nonlaser dacryocystorhirtostomy (End-DCR). A total of 214 Ex-DCR performed to 208 patients operated from the 1996 to 2002 and a total 118 End-DCR of 116 patients were reviewed. The follow up period was at least one year. Three techniques were performed in each group. Patency of the drainage system was assessed by history and irrigation. A full success was achieved in 86% of Ex-DCR group and 77.1% among End-DCR group by dyferent techniques. The operating time, dffficulties, postoperative recovery time and complications were compared. The Ex-DCR has a higher success rate compared to the End-DCR. However, End-DCR has a shorter operative time, no external scar es. and more suitable for recurrent cases.
