Endoscopic Dacryocystorhinostomy is useful in treating patients diagnosed with nasolacrimal duct obstruction or lacrimal sac. It also causes chronic stenosis in the nasolacrimal duct but these are not serious health conditions. The endoscopic DCR treatment is much suitable to treat the tearing due to blockage of nasolacrimal duct. Normally, the tears originate in the lacrimal glands that are located in the upper outer margin of the eye. It also presents the symptoms that include epiphora (tearing) as well as dacryocystitis (infection). Initial treatment would be conventional with warm compresses, probing the nasal passage and massage. The DCR is a standard treatment, which uses a minimal invasive procedure that is performed by an Ophthalmologist to unblock tear ducts as well as for correcting them along with many other causes for decreasing the patency of nasal passage. In the procedure, the rigid endoscope will be inserted in the nasal cavity into the lacrimal sac through blocked tear duct for exploring as well as conforming nature of the obstruction. Nasal mucous membrane are removed that would allow the creation of window based on lacrimal sac and upper nasolacrimal duct. Decongestants are administered for clearing the nasal passage then gauze will be soaked for anesthesia to numb the area and it would automatically constrict the blood vessels. The DCR surgery is efficient for clearing nasal passage for removing the blockage of the lacrimal sac in the nasal cavity. Both the ophthalmologist as well as otolaryngologist would do evaluation and management of the tearing.
