Purpose: A retrospective study to compare outcomes after external dacryocystorhinostomy
(Ex-DCR) and transnasal endoscopic assisted nonlaser dacryocystorhinostomy (End-DCR).
Patients and Methods: A total of 214 Ex-DCR performed to 208 patients 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.
Results: 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
different techniques. The operating time, difficulties, postoperative recovery time and
complications were compared.
Conclusion: The Ex-DCR has a higher success rate compared to the End-DCR. However,
End-DCR has a shorter operative time, no external scar and more suitable for recurrent
cases. |
