| Popis: | PURPOSE. To present our initial results in the treatment of nasolacrimal obstruction by placing a polyurethane stent. METHODS. 74 nasolacrimal stents were implanted under fluoroscopic guidance in obstructed nasolacrimal systems of 64 patients. Dacryocystography and CT were used to verify the position and patency of the stents. Mean follow-up was 15 months. Clinical examinations were done at the first week, first month, third month and sixth month after stent placement. RESULTS. Polyurethane stents were successfully inserted and permeable in 59 patients (92.1%), but could not be inserted in 5 patients (7.8%). Epiphora was solved and permeable in 53 cases (82.8%), it was not permeable but asymptomatic in 2 cases (3.1%), and was not permeable but symptomatic in 4 (6.2%). In 5 cases (7.8%) stents remained permeable although patients complained of epiphora. CONCLUSIONS. Polyurethane stent placement is a non-invasive technique that can replace dacryocystorhinostomy, giving better results and tolerance. |
