Endoscopic Dacryocystorhinostomy (DCR) is a minimally invasive surgical procedure used to treat nasolacrimal duct obstruction by creating a direct drainage pathway between the lacrimal sac and the nasal cavity. This technique offers advantages such as reduced scarring, faster recovery time, and improved patient outcomes compared to traditional external approaches.

Nasolacrimal duct obstruction is a condition where the tear duct that drains tears from the eye into the nasal cavity becomes blocked, leading to excessive tearing and potential infection. It can be congenital or acquired, with treatment options ranging from simple massage techniques to surgical intervention depending on severity and cause.

Nasolacrimal Duct Obstruction

Direct drainage pathway

The lacrimal sac is a crucial component of the tear drainage system, located in the medial canthus of the eye, responsible for collecting tears from the eye surface before they drain into the nasolacrimal duct. Its proper functioning is essential for maintaining eye health and preventing tear overflow, which can lead to conditions such as dacryocystitis if blocked or infected.

Lacrimal Sac

The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face, playing a crucial role in respiration, olfaction, and filtration of inhaled air. It is lined with mucous membranes and tiny hairs that help trap dust and pathogens, while also warming and humidifying the air before it reaches the lungs.
