Abstract:
Dacryocystorhinostomy (DCR) is a surgical procedure in which a connection is established between the lacrimal sac and the nasal cavity in an effort to bypass an obstruction of the distal lacrimal apparatus. Endoscopic endonasal DCR (EEDCR) is a minimally invasive technique used to achieve this goal. In patients with altered anatomy, EEDCR can be challenging. Here, we describe the use of canalicular transillumination with EEDCR in three cases, and discuss the benefits of this technique.
