Dacryocystorhinostomy (DCR) involves the treatment of blockages in the tear ducts. Lacrimal glands located on the upper outer margin of the eye are responsible for the production of tears. The tears take along the path and pass through several channels and ducts before entering the lacrimal sac. The lacrimal sac located between the eye and the nose channelizes the tears into the nasal cavity through the nasolacrimal duct. A blockage in any of the various channels and ducts may interfere with the smooth flow of tears. This condition causes overproduction of tears or tearing. The diagnosis of the cause of blockage determines the course of treatment. A blockage of the nasolacrimal duct is a common cause of tearing. Creating a direct opening from the lacrimal sac into the nasal cavity can treat the condition and the procedure is known as DCR. Blockage of this duct can be due to several reasons including trauma, prior surgery, tumor, or inflammatory medical conditions. Surgery may be performed under general or local anesthesia. A small incision can be made on the face to reach the duct or the procedure may be performed with an endoscope through the nose. The procedure does not touch the obstructed nasolacrimal duct, instead, it channelizes drainage of tears directly from the lacrimal sac into the nasal cavity. Sutures or stents is placed at the opening to make it permanent. DCR is an effective option for patients with this condition that bypasses the need for a facial incision.
