·AIM:To compare the effect of nasolacrimal duct stent placement and dacryocystorhinostomy for chronic dacryocystitis.METHODS:From February 2008 to February 2010,44 patients with chronic dacryocystitis were examined in our hospital.All paitients were divided into two groups,group A(22 cases)was treated with nasolacrimal duct stent placement;group B(22 cases)received dacryocystorhin-ostomy.The intraoperative and postoperative complications and treatment effects were compared.Follow-up period was from 3 to 6 months postoperatively.The effective evaluation was improvement of epiphora and unobstructed irrigation of lacrimal passage.RESULTS:The postoperatively successful rate of nasolacrimal duct stent placement was 91%,the effective rate was 86%;The postoperatively successful rate of dacryocystorhinostomy was 100%,the effective rate was 82%.CONCLUSION:Nasolacrimal duct stent placement has higher postoperatively effective rate and lower postoperatively successful rate.
