[Nasal intubation with silastic tubes in dacryocystorhinostomy and experiences with the Piza approximator]

The technique of intubation of the lacrimal pathways can be facilitated by using a Piza approximator for connection of the ring intubation, or two 15 mm long rods of a Bowman probe connected to silicone tubes for nasal intubation, with a double tantalum clip for closure of the loop in dacryocystorhinostomy.
