Which statement is accurate regarding DCR?

Which statement is accurate regarding DCR?

• A. It is never performed with nasal endoscopy
• B. It always requires general anesthesia
• C. It cannot be performed on one eye only
• D. It aims to create a direct connection between the lacrimal sac and nasal cavity

Answer: (D)

Dacryocystorhinostomy is done to bypass a blockage in the tear drainage pathway by creating a direct opening between the lacrimal sac and the nasal cavity, allowing tears to drain normally into the nose. This can be done through an external approach or via endoscopic (nasal) techniques, and nasal endoscopy is commonly used to visualize and guide the new ostium. It does not require general anesthesia in every case; local anesthesia with sedation is also possible. It can be performed on one eye, so unilateral DCR is routinely done when only one side is blocked. Thus, the statement that it aims to create a direct connection between the lacrimal sac and nasal cavity is accurate.
