Hello and thank you for your question. Unfortunatetly some patients sort of reject permanant suture. This can happen at any time. This happened to 2 of my patients when using merseline suture. I've since stopped using permanent suture in all my body contouring patients and hav not seen this again. Hopefully this is your last one.
Permanant sutures offer the advantage that they do not dissolve and so offer continued support. However, as they don not dissolve, the sutures can push themselves through the skin. See your surgeon and she/he can best advise you.
