External dacryocystorhinostomy versus endoscopic non-laser dacryocycstorhinostomy " A comparative study"

A retrospective study to compare outcomes after external dacryocystorhinostomy [Ex-DCR] and transnasal endoscopic assisted nonlaser dacryocystorhinostomy [End-DCR]. A total of 214 Ex-DCR performed to 208 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. 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

Endonasal endoscopic dacrocystorhinostomy with application of a self retaining tube

Endoscopic endonasal approach to do dacrocystorhinostomy was used to treat cases of post saccal obstruction with insertion of a T tube in the inferomedial wall of the sac. The study was conducted in Benha university hospital. ENT department. 10 patients were included in the study in age range from 16 to 45 years. Endonasal endoscopic dacrocystorhinostomy with application of a silicone self-retaining T tube in the inferomedial saccal wall removed after 6 months. 12 months follow up proved 90% success rate. The procedure used in this study proved to be simple. direct and physiological with relatively short operative time and got satisfactory success rate
