Had "ear pinning back" surgery when I was 12 and there were sutures left inside - what type of doctor should I consult?

I had "ear pinning back" surgery when I was around 12 in another country but a lot of non dissolvable sutures were left inside ears and slightly protruding out of my cartilage. I am now 33 and every now and then it gets red and swollen and tender with puss. No doctor I have seen can help me because it's cosmetic and was done out of country. The sutures seem embedded. What would be correct doctor in Miami that I need to see and the price because I am sure insurance doesn't cover. Thabk you.
