Spitting stitches 1.5 years post tummy tuck - Is this normal? (photos)

No, this is not normal this far out from surgery. perhaps these are not dissolving stitches, but permanent. However, I have removed dissolvable stitches at never dissolved 5 years out from surgery from an ankle.

Thank you for your question regarding sutures surfacing five years after your procedure. Based on your history and images, it appears you are experiencing suture rejection. This can happen when permanent sutures, which are commonly used to tighten the rectus abdominis or "six-pack" muscles during a tummy tuck, become infected or rejected by the body.
In my opinion, treatment should be aggressive when this occurs. An incision should be made over the emerging wound, and the problematic suture should be located and removed. The condition doesn't necessitate a complete redo of your procedure, but each surfacing suture should be dealt with promptly and decisively.
Sincerely,
Dr. Katzen

Hello and thank you for your question! Spitting sutures are a frustrating post op possibility in plastic surgery and the course/severity of issues really depends on the timing and type of suture material used. If permanent suture material was used and you are experiencing chronic, recurrent issues far out after surgery not resolved by measures such as antibiotics and local wound care therapy, there is a chance you may need a revision procedure to remove the remaining suture material. I recommend following up with your surgeon as they would know the type of suture material used, and/or a second opinion from a board certified plastic surgeon.
