Özet

A Song's nasolacrimal duct stent was placed in a patient with epiphora due to primary nasolacrimal duct obstruction and the stent was kept for 32 months. Mitomycin C 0.02% eye drops four times a day were prescribed for four weeks following polyurethane stent placement procedure. No epiphora-related complaints occurred for thirty months after then the epiphora started. Nasolacrimal stent was removed from nasal cavity endoscopially and the tissues within the extruded stent were examined histopathologically. The patient's complaints were relieved following stent removal. Dacryocystogram revealed normal passage and a filling defect within the lacrimal sac. Macroscopic evaluation of the stent revealed a firm mass in the stent mushroom, causing complete obstruction. Pathological examination of the mass revealed chronic inflammation, increased connective tissue and vascular proliferation.
