Dacryocystorhinostomy

Dacryocystorhinostomy (pronunciation: dak-ryo-cysto-rhino-stomy) is a surgical procedure performed on the lacrimal apparatus to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function.

Etymology

The term "Dacryocystorhinostomy" is derived from the Greek words "dakryon" (tear), "kystis" (sac), "rhinos" (nose), and "stoma" (mouth or opening).

Procedure

During a Dacryocystorhinostomy, a new tear drain opening is created from the lacrimal sac into the nose. This allows tears to bypass the blocked part of the tear drain for normal flow from the eye into the nose.
