A retrospective study to compare outcomes after external dacryocystorhinostomy
(Ex-DCR) and transnasal endoscopic assisted nonlaser dacryocystorhinostomy
(End-DC!?). A total of 214 Ex-DCR performed to 208
patients operated from the 1996 to 2002 and a total 118 End-DC!? of 116
patients were reviewed. The follow up period was at least one year.
Three techniques were performed in each group. Paiency 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
different techniques. The operating time, difficulties, 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. |
