Endoscopic dacryocystorhinostomy: An evaluation for lacrimal patency and eye watering recurrence
Main Article Content
Abstract
Endoscopic dacryocystorhinostomy (DCR) has nowadays become the first choice in the management of nasolacrimal duct obstruction. The aims of this study were to describe the anatomic success rate and the causes of failure after DCR. This was a prospective study on 84 cases with endoscopic DCR. All patients were examined to assess lacrimal patency and ostium opening through nasal endoscopic examination. The rate of anatomic patency gradually decreased to 86.91% 6 months after surgery, then remained stable up to 12 months. 63.64% failures had more than one cause. The most common causes were fibrotic scarring of the ostium (100%) and obstruction of the common canaliculus (27.27%). To conclude, DCR helps with lacrimal patency. However, failures existed and the most common causes of recurrence are ostium fibrosis and obstruction of common canaliculus.
