Abstract: Objective To observe the clinical effects of the recessive placement of spherical headed silicone tube on treatment of chronic dacryocystitis. Design Retrospective case series. Participants 65 patients ( 67 eyes) with chronic dacryocystitis. Methods All the participants were accepted the operations of the recessive placement of spherical headed silicone tube. Using the method of probing of lacrimal passage, the traction line was sent into the inferior nasal meatus using the 8-pin, after the expansion of nasal tube using the expansion rope, the ball head silicone tube was tracted retrogradely guaided by the traction line and implanted. Then the lacrimal passages were washed with plus gentamicin and dexamethasone mixture and saline irrigation after the operation once a day in one week, after 1 week once a week, for 3 months, and the tube was removed three to six months after placing. The lacrimal passages were washed with antibiotic and hormone (about 4 times), the tube was injected with TobraDex after the tube was removed. The symptoms were observed in the following 3 months to 2 years.  Main Outcome Measures The symptom of epiphora and pus, the situation of lacrimal duct. Results After the tube planting,  the lacrimal duct system of totally 65 patients (67 eyes) were able to be irrigated successfully. 49 eyes（73.13%） were cured after the removal of silicone tube during the follow-up period, and the symptom of epiphora and pus disappeared, there were no serious intra- and post-operative complications. Conclusion Recessive placement of spherical headed silicone tube is an effective method for the most chronic dacryocystitis. (Ophthalmol CHN, 2014, 23: 126-129)
