I have atopic dermatitis on my ears (tops), corticostriod creams did not help!?

May not be atopic. In general atopic dermatitis responds well to topical steroids. If they are not working at all then it is possible that the diagnosis is not correct. Also, many atopic derm patients may have concomitant bacterial infection in some affected areas. Confirming such a co-existing problem and treating it appropriately will allow the steroids to work better. You probably should be seen.
