AIM: To study the clinical effect of modified dacryocystorhinostomy for chronic dacryocystitis.

METHODS: A retrospective analysis was conducted in our hospital from February 2014 to January 2016 including 168 patients(168 eyes)with chronic dacryocystitis.

According to the difference of treatment for patients we established two groups, the observation group of 87 cases underwent modified dacryocystorhinostomy treatment, 81 cases in the control group underwent the conventional dacryocystorhinostomy. Perioperative indexes, lacrimal patency and complication rate of two groups were compared.

RESULTS: The operative time, hospitalization time and bleeding amount of the observation group were significantly less than those of control group(P<0.05). The total efficiency of the observation group was significantly better than that of the control group, while the postoperative complication rate and recurrence rate were significantly less(P<0.05).

CONCLUSION: The modified dacryocystorhinostomy is easy to operate, the operation time is short, the complications are few, the curative effect is accurate, it is the effective surgical method for the treatment of chronic dacryocystitis.
