Is it normal to still have sutures left 3 years post reduction? (Photos)

Thank you for your questions and photographs. 
It’s possible that there is a suture underneath your skin and soft tissue, depending on the type of sutures your Plastic Surgeon used during your procedure. As far as keloid scarring, techniques of excision, steroid injection, and radiation therapy are all regimens that have been used in attempts to treat this. 
I recommend you follow-up with your Plastic Surgeon. He or she will be able to answer your questions and guide you with how best to proceed. 
I hope this is helpful, best of luck to you.

A small procedure could be done called a scar revision  This would remove the scar and also remove the suture that is still in place . Can be done under local.   Best to ask your board certified plastic surgeon. Good luck. Andrew Cohen, MD
