Objective:
To evaluate the technique and curative effect of modified intranasal endoscopic dacryocystorhinostomy (EDCR) for chronic dacryocystitis.
Method:
Twenty-two patients (Twenty-three eyes)with chronic dacryocystitis, undergoing modified intranasal EDCR were retrospectively analyzed in this study.
Result:
The follow-up period ranged from six months to ten months. Twenty eyes were cured successfully and two eyes had relieved symptoms. While one case failed. No serious complications were found. The total effective rate was 22/23 (95.7%).
