Dacryocystectomy (DCT) is a surgical procedure that involves the complete removal of the lacrimal sac, which is part of the tear drainage system. It is usually performed in cases of chronic dacryocystitis (infection of the lacrimal sac) when other treatments are not suitable or if there is suspicion of a tumor in the sac. Unlike dacryocystorhinostomy (DCR), which creates a new tear drainage pathway, DCT removes the infected or damaged sac entirely, thereby eliminating the source of infection and preventing recurrent swelling or discharge. The procedure is generally safe, performed under local or general anesthesia, and provides long-term relief from symptoms.

• Surgical removal of the lacrimal sac.
• Used for chronic dacryocystitis or suspected tumors.
• Eliminates infection source and prevents recurrence.
• Does not restore tear drainage like DCR.
• Performed under local or general anesthesia.
• Provides long-term relief from swelling and discharge.
