The follow up period was at least One year. techniques were performed in each group. Patency of the drainage system was assessed by history and irrigation. A full success was in 86% of Ex-DCR group and 77.1% among End-DCR group by techniques. The operating time, difficulties, postoperative recovery time and complications were compared. The Ex-DCR has a higher success rate compared to the End-D CR. However, End-DCR has a shorter operative time, no external scar es. and more suitable for recurrent cases
