AIM: To discuss the clinical efficacy of dacryocystorhinostomy(DCR)associated with lacrimal duct drainage tube placement for treatment of chronic dacryocystitis and lacrimal duct stenosis.

METHODS: For 41 patients with chronic dacryocystitis and lacrimal duct stenosis, DCR has been given. And during DCR operation, lacrimal duct was probed and a new type drainage tube was planted for 3 to 6 months. Three months later after removal of drainage tube, flow of tears, pus excretion and lacrimal duct clearance were observed.

RESULTS: Upon removal of drainage tube, clear lacrimal duct ratio was 100%. Three months after tube removal, rechecking reports 38 cases with clear lacrimal duct(93%, 38/41)and 3 cases with block duct(7%, 3/41). Except for 8 cases with minor lacerations, no other complications were observed.

CONCLUSION: DCR associated with lacrimal duct drainage tube placement is an effective treatment for chronic dacryocystitis and lacrimal duct stenosis. Surgical equipment required a simple, small difficulty operation, operation under direct vision, which makes it a very applicable good method at primary hospital.
