Will suture knots dissolve after mini and neck lift?

Suture knots are usually caused by absorbable sutures that are present under the skin.  These sutures are important as they hold the final result in place for months deep under the skin.  Sometimes these sutures dissolve and sometimes your body will 'spit' them out.  There are several sutures so if 4 or 5 work their way out, it's perfectly fine.  Communicating with your surgeon, as you have, is the best treatment. 

It is possible that the sutures underneath the skin can come through the skin after a mini facelift procedure. If the sutures do come through the skin, they can be easily removed and the area should heal normally. It would be unusual, if this left a scar or any mark in the area.Unfortunately, if you're going to be away from your home state during this time, you may need to see a plastic surgeon at your current place of residence, this should be a rather easy issue for a qualified plastic surgeon or facial plastic surgeon to handle.I hope this helps

You should have your surgeon evaluate you to ensure these are knots you are feeling and that they will dissolve.   If they are only palpable and not visible, it may be fine to wait until they dissolve.  If they are also visible, you may need to have them removed.
