AIM: To investigate the clinical effect of dacryocystorhinostomy in treating recurrent dacryocystitis by nasal endoscopy.

METHODS: Totally 18 cases(18 eyes)of recurrent dacryocystitis were operated with dacryocystorhinostomy by nasal endoscopy from March 2007 to June 2012. During the dacryocystorhinostomy, the hole in the bone was expanded, and adhesion sites were separated. Blood clot, scar, granulation, and other lesions were cleared up. Nasal steroids were used after operation.

RESULTS: The patients were followed up for 6-12 months after operation. Fifteen cases(83.3%)were cured, 2 cases(11.1%)were improved, 1 case were failed. The total effective was 94.4%.

CONCLUSION: Dacryocystorhinostomy appears to be an effective and safe filtering procedure in recurrent dacryocystitis with the advantage of having fewer complications. It is worthy of clinical application.
