Abstract
Lacrimal stents were used in the past to preserve the caliber of the lacrimal pathways after surgery, trauma, reconstruction, etc. Recently, their role in preventing functional epiphora has also been highlighted. Over the years, the stents have evolved and different models, materials and surgical techniques for positioning have appeared. Extensive and accurate knowledge of the type and design of the stent, the correct insertion technique offer optimal results depending on the anatomical area and the type of disorder of the lacrimal pathways. We will present the advantages of a simple catheterization technique for the lacrimal sac, endoscopic post-dacryocystorhinostomy.
