[The effect of endoscopic dacryocystorhinostomy on different lacrimal duct obstruction]

Objective:To observe the effect of endoscopic dacryocystorhinostomy on different lacrimal duct obstruction. Methods:Eighty eyes with the lacrimal passage obstruction were collected, and treated with endoscopic dacryocystorhinostomy. Meanwhile, the abnormal structures of the nasal cavity were corrected and the pathological changes of the nasal cavity and sinuses were treated. The patients were followed up and the curative effect was observed. Follow-up period ranged from 10 months to 8 years. Results:The first operation cure rate was 78.8%, the effective rate was 17.5%, the ineffective rate was 3.8%, and the success rate was 96.2%. Two of the 3 eyes failed in first operation were cured by reoperation. The total success rate was 98.8%. Conclusion:Endoscopic dacryocystorhinostomy can be used as a routine operation in the treatment of different lacrimal duct obstruction. The structural abnormalities and pathological changes of the nasal cavity and paranasal sinuses can be treated simultaneously. Combined with postoperative treatment and follow-up, long-term curative effect can be obtained.
