Which procedure is considered definitive treatment for acquired NLDO?

• A. Dacryocystorhinostomy
• B. Dacryocystectomy
• C. Canaliculitis management
• D. Blepharitis treatment

Answer: (A)

Dacryocystorhinostomy creates a new drainage pathway between the lacrimal sac and the nasal cavity, bypassing the blocked nasolacrimal duct. This restores tear outflow and provides lasting relief from epiphora, making it the standard, definitive treatment for acquired NLDO. It can be performed externally or endonasally, with high long-term success rates. Removing the lacrimal sac (dacryocystectomy) does not reestablish drainage and is not used to treat NLDO, while managing canaliculitis or blepharitis targets different conditions and won’t cure NLDO.
