Of course, it is hard to say without examining you. There is complex interaction between the skin, cartilage and scar in an already complex three-dimensional area with minimal to no support on the very edge. All this can cause less than desireable/predictable changes sometimes. I don't know the time from your surgery, but if it has been 6-12 months, this is not likely to improve any more. I have successfully used filler to improve a poorly supported area of the rim.
