Abstract
External dacryocystorhinostomy is a traditional lacrimal bypass surgery used to treat epiphora or dacryocystitis due to nasolacrimal obstruction at the level of the lacrimal sac or nasolacrimal duct. It requires a patent and functioning upper lacrimal system. The surgery has a steep learning curve, and many peri- and intraoperative considerations are important to help ensure a high rate of success.
