Will my ears change through-out my life after an otoplasty?

Hi, Ive had an otoplasty a year ago. I do not currently talk to the surgeon that preformed it, as we fell out, hence why I can't ask him. Please could you answer my following questions: 1) Will my ear ever return to how they were? 2) Should I still be wearing a headband? 3) Behind my ears i get a lot of dead-skin build up, how do i clean it without damaging my ears? 4) Why are my ears still having a troll on my life (negativity).
