AIM: To observe the effect of dacryocystorhinostomy for the treatment of chronic dacryocystitis using nasal endoscope and discuss the operation technique.

METHODS:A retrospective clinical analysis was performed on the clinical data followed up for 6～12mo from 140 patients(169 eyes)with dacryocystorhinostomy for the treatment of chronic dacryocystitis using nasal endoscope. The effect of the treatment was evaluated and the operation technique for the treatment of chronic dacryocystitis using nasal endoscope was discussed.

RESULTS: In all of cases 155 eyes(91.7%)were recovery, 3 eyes(1.8%)were improved, and 11 eyes(6.5%)were failure. The total efficiency was 93.5%, there was no significant difference compared with traditional dacryocystorhinostomy group(χ²=3.743, P>0.05).

CONCLUSION: Dacryocystorhinostomy using nasal endoscope for treatment of chronic dacryocystitis has a good curative effect.Techniques including lacrimal sac location and size, colostomy position and size, treatment of colostomy mucosal flap and nasal disease, postoperative follow-up and physical condition of patients are likely to affect the operation curative effect.
