Abstract. Purpose:To report findings by nasal endoscopy in functional obstruction of nasolacrimal duct. Cases:This study was made on 316 sides of 158 patients who presented with epiphora. The patients were examined by nasal endoscopy. Findings:The shape of inferior aperture of nasolacrimal duct could be classified into 4 types:wide open 40 sides,valve-like 26 sides,sleeve-like 43 sides and adhesive 207 sides. In 57 sides with functional obstruction of nasolacrimal duct manifesting adhesive inferior aperture,dye fluid outflow into the nasal cavity was observed in 7 sides,expansion of inferior membraneous nasolacrimal duct during irrigation occurred in 39 sides,outflow of putrid matter in 12 sides,outflow of dacryolith in 8 sides,and blood outflow in 8 sides among others. Conclusion:Preoperative nasal endoscopy is useful in evaluation functional obstruction of nasolacrimal duct.
