dacryocystorhinostomy

With the advent of nasal endoscopes, endoscopic dacryocystorhinostomy is becoming popular.

Malhotra has developed two instruments used in endoscopic dacryocystorhinostomy (DCR):

The mainstays of treatment are oral antibiotics, warm compresses, and relief of nasolacrimal duct obstruction by dacryocystorhinostomy.

A surgical procedure called a dacryocystorhinostomy is done to join the lacrimal sac to the nasal mucosa in order to restore lacrimal drainage.

In case of elderly patients (above 70 years of age), dacryocystectomy is preferred to dacryocystorhinostomy as old age naturally causes atrophy in nasal mucosa.

A dacryocystorhinostomy (DCR) or dacryocystorhinotomy is a procedure to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function.

It is also in use in dacryocystorhinostomy surgery in which the lacrimal sac mucosa is connected to the nasal mucosa above the level of the mechanical obstruction at the nasolacrimal duct.
