• When the condition persists, it can be treated by dacryocystorhinostomy (DCR), a procedure that creates an alternative route for tears to drain by connecting the lacrimal sac to the nasal cavity.
• This procedure can be performed either through external DCR or endonasal DCR.
• An external DCR procedure involves making an incision on the side of the nasal bridge, while an endonasal DCR involves operating inside the nasal cavity with or without an endoscope or operating microscope.
