Brief summary
Endoscopic dacryocystorhinostomy (EN-DCR) is an effective procedure when treating saccal and postsaccal obstructions of the nasolacrimal pathway. The benefit of silicone tubing after DCR is still controversial. We conducted a prospective, randomized study in order to evaluate 1) the necessity of bicanalicular silicone tubes after primary EN-DCR, 2) efficacy of the perioperative Mitomycin C for the prevention of adheesion and re-stenosis of rhinostomy site in revision EN-DCR, 3) the subjective symptoms and QoL changes before and after DCR-operation.
Interventions
The patients were randomized into the two study groups, either with or without the insertion of a bicanalicular silicone tube after primary DCR. In revision group patients were randomized into the two groups,ether with or without application of mitomycin C after DCR
