Abstract

Dacryocystorhinostomy or DCR is one of the most common oculoplastics surgery performed. It is a bypass procedure that creates an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium. It may be performed through an external skin incision or intranasally with or without endoscopic visualization. This article will discuss the indications, goals, and simple techniques for a successful outcome of an external DCR.
