My ear is flat and uneven. What can I do to fix it?

When i was really young, i had multiple surgeries on my left ear to remove a cholesteatoma and later reconstruct it. Since then, i've grown up and began to notice my ears are uneven. My left (surgically altered) ear is flat to my head, while my right protrudes the normal amount. Does anyone know why this might be, and what can be done about it? Thanks.
