Intranasal stent for stabilization and fixation of interstitial radioactive isotopes

This article introduces the use of an intranasal stent for the stabilization and fixation of afterloading catheters during interstitial radiation therapy. After catheters have been positioned to desired locations within the stent, they are immobilized with light polymerizing resin. The fixation of the catheters to the stent allows the radiotherapist to afterload predetermined radiation sources to desired locations. This technique maximizes tumor response and minimizes untoward effects to normal surrounding tissues.
