Question

Quizplus · Accepted Answer

Dacryocystorhinostomy (DCR)is the establishment of a new tear passageway for drainage directly into the nasal cavity.Dacryocystitis is an infection in the lacrimal sac,which may result in a localized cellulitis.Chronic or recurrent dacryocystitis in adults may necessitate probing or DCR because of resistant obstruction of the nasolacrimal duct related to infection-associated scarring,dacryolith (calculus in the duct),or trauma.Another indication for DCR surgery may be intolerable epiphora (tearing)resulting from tear duct laceration following medial orbital wall fracture.
