There is a product called moleskin that is from Dr. Scholls....take a piece of that, hold it to the ear and trace the ear then cut out the trace. Make sure the inside of the ear is nice and dry, cleaning it prior with alcohol to help. Stick the moleskin to the inside of the ear and it will help hold the ear up while giving air circulation.
Let me know if you have any other questions
Good Luck &
Best Fishes
