Clinical Study of Nasolacrimal Duct Stent in the Treatment of Nasolacrimal Duct Obstruction

Objective To discuss the clinical results of interventional placement of nasolacrimal stent in the treatment of nasolacrimal duct obstruction. Methods Using song 601 nasolacrimal duct stent set,3 polyurethane stents were placed in 5 patients with epiphora secondary to obstruction of the nasolacrimal duct in retrograde fashion through nasal cavity. Results Technical success rate was 100%. The dacryocystography after stenting immediately demonstrated patency of naso!acrimal duct. During the follow up of 6 to 12 months, after 7 months,one case appeared the recurrence of epiphora,the other two maintained complete resolution. Conclusions The interventional nasolacrimal stent placement technique is simple,safe and effective in treatment of nasolacrimal system obstruction.
