When I was the athletic trainer for the wrestling team at the university of wisconsin-Madison, we made a little cast for the ear. We would use a special guaze cut in strips and soak it in collodian. We would then put in on the ear and form it around. It would then harden and form a cast around the ear applying gentle pressure. But if you have been around college wrestlers, they mostly don't care about cauliflower ear. Somewhat like a badge of honor for them.
