Official Title: Recovery After Endoscopic Dacryocystorhinostomy

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.

Detailed Summary:
Sponsor: Kuopio University Hospital

Current Primary Outcome: The success rate after primary DCR with and without silicone tubes. The success rate after revisio DCR with and without Mitomycin C. [ Time Frame: 5 years ]

Original Primary Outcome: Same as current

Current Secondary Outcome: The EN-DCR operation influence on the patients subjective symptoms and QoL before and after operation. [ Time Frame: 5 years ]

Original Secondary Outcome: Same as current
