Chronic dacryocystitis surgery is performed to treat chronic inflammation of the lacrimal sac, typically caused by blocked tear ducts that result in recurrent infections and excessive tearing. The goal of the surgery is to create a new drainage pathway for the tears, bypassing the blockage and restoring normal tear flow. This is typically done through a procedure called dacryocystorhinostomy (DCR).

DCR involves creating a new opening between the lacrimal sac and the nasal cavity, allowing tears to drain properly into the nose. In some cases, a silicone tube is used to keep the new passage open during the healing process.

Chronic dacryocystitis surgery is highly effective in relieving symptoms of excessive tearing, eye infections, and discomfort caused by blocked tear ducts. The procedure is performed under local anesthesia, and recovery times are generally short, with most patients experiencing significant improvement in their symptoms.
