dacryocystorhinostomy
Pronunciation: dak-ree-oh-sis-toh-rye-NOS-toh-mee
Surgical creation of a new drainage pathway between the lacrimal sac and nasal cavity to treat blocked tear ducts.
Full Definition
Dacryocystorhinostomy (DCR) is a surgical procedure designed to bypass nasolacrimal duct obstruction by creating a direct connection between the lacrimal sac and the middle meatus of the nose. The surgery can be performed via external or endonasal approaches, with the latter gaining popularity due to reduced scarring and faster recovery. A silicone tube is often placed temporarily to maintain patency of the new drainage pathway.
Usage
Usage note: Commonly abbreviated as DCR in clinical practice; specify external vs. endonasal approach.
