Silicone intubation is commonly performed to maintain patency of the lacrimal drainage system. We describe a new lacrimal groove director, designed to simplify retrieval of the metal Crawford probe with minimal trauma to the nasal mucosa. This instrument can also be used to infracture or medialize the inferior turbinate in both pediatric and adult populations during nasolacrimal duct intubation or external or endoscopic dacryocystorhinostomy.
