Experimental studies on the treatment of unilateral vocal cord paralysis.
After the injection of Teflon and Silicon behind the vocal cords of sheeps we noticed that these materials are quite well supported. The little particles of Teflon are surrounded by conjective tissue wheras the Silicon is enclosed in an unic membrane. We could not see a migration of the materials in the depth.
