AIM: To analyze the reasons of dacryocystorhinostomy failure and the corresponding managements.

METHODS: From August 2003 to February 2013, 34 patients(34 eyes)who had a previous failed dacryocystorhinostomy were re-operated in my hospital. This paper analyzed the reasons of operation failure, discussed corresponding managements. The postoperative follow-up time was from 6mo to 4a. Success of the operation was achieved in 33 of these 34 eyes, not effect in 1 eye.

RESULTS: The main reasons of the failure of dacryocystorhinostomy were: anastomotic granulation tissue congestion, bone hole locations were not correct, intraoperative bleeding, bone holes were too small, the decryocysts were un-incision.

CONCLUSION: Preoperative perfect relevant examination, intraoperative careful operation, reducing intraoperative bleeding, making the perfect size and location bone hole and lacrimal duct flushing on time can reduce the occurrence of failure. Re-operation of dacryocystorhinostomy is effective in these patients who had a previous failed dacryocystorhinostomy.
