Nasolacrimal ductus obstruction cause Epifora. Two widely accepted treatment modalities are external and endoscopic dacryocystorhinostomy. Currently available rigid nasal endoscopes are safe for intranasal manipulation of structures of the nasal cavity, including the region of the lacrimal sac. Twenty-eight patients with complete stenosis of the nasolacrimal duct were treated with endoscopically controlled endonasal dacryocystorhinoslomy. Approximately 97% of the patients were symptom free, and 3% of these felt improved postoperatively. This procedure appears to be safe and effective, which should be considered as an alternative to external dacryocystorhinostomy for the surgical treatment of the nasolacrimal duct obstruction.
