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

Removal of long lasting, embedded in the cartilage sutures, may require very tedious procedure, possibly excision of strip of the cartilage where sutures are placed. Only that way you will be permanently released of this problem. Good luck.

You should check with some of the plastic surgeons or facial plastic surgeons in the area. If they have training in pediatric craniofacial surgery, they most likely will have done many of these procedures and can help you out. Happy to have a complementary video consultation with you sometime if you are interested. Good luck!
