Conjunctivodacryocystorhinostomy tube placement with a urologic catheter.

In an endoscopically performed conjunctivodacryocystorhinostomy, insertion of a Jones glass tube can be difficult if the nasal end of the tube draws soft tissue around the tunnel in front of the tube. A urologic Tiemann catheter has been used for Jones tube placement in 44 cases since 2001. The tube is put in the lumen end of the catheter, the tip of which is bulbous and gradually tapered in its diameter. The catheter can be easily inserted into the tunnel and pulled out of the nose with forceps, leaving the glass tube in the tunnel.
