Severe CCO was confirmed intraoperatively by soft resistance to probing \u226510\u2005mm from the punctum. The surgical technique included wide bony ostium creation, lacrimal sac marsupialization, direct endoscopic incision of the fibrotic common canaliculus, and bicanalicular silicone tube intubation (stent removed at 3 months). Outcomes were assessed at \u226512 months postoperatively using epiphora symptom resolution, lacrimal irrigation, nasal endoscopy, and fluorescein dye disappearance test. Anatomical success was defined as a patent ostium with unobstructed irrigation; functional success required anatomical patency plus complete epiphora resolution.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At a mean follow-up of 18.8\u2009\u00b1\u20096.9 months, anatomical success was achieved in 37 eyes (86.0%), and functional success in 35 eyes (81.4%). Failures included 5 cases of ostial fibrosis and 1 recurrent CCO; 2 patients reported persistent epiphora despite anatomical patency.
