A Simple Technique to Avoid Restenosis for Dacryocystorhinostomy.

The most common reason for failure in dacryocystorhinostomy has been proven to be the granuloma or membranous obstruction of scar tissue formation on lacrimal opening in the nasal cavity during the healing process. In this article, the authors suggest an easy maneuver to avoid the risk of scarring and collapsing of the knot in bony window by using a piece of an aspiration catheter. Using this easy maneuver, the authors can manage to reduce the risk of scarring and stenosis, and when the authors take out the tubes after 2 months, removing the silicone tube was easier with our technique. Moreover with the present technique the authors observed there was no embedding of the knot in the scar.
