When will my stitches from otoplasty dissolve?

You should contact your plastic surgeon's office and let them know the sutures are not dissolving.  

I have performed countless numbers of these procedures.  For patient comfort, I typically place dissolvable sutures in the incision, that is always positioned in the crease behind the ear, and never in the front.Sutures typically go away by a week or two.  If material remains, I recommend gentle washing behind the ears to eliminate the material.  Follow up with your surgeon is always critical!Best of luck!
