Why are anchor sutures used and how long does it take them to dissolve?

Thank you for sharing your question.  Progressive tension or quilting stitches are often used to help speed the recovery process of a tummy tuck by minimizing dead space and encouraging the skin and adipose flap to seal down to your muscles faster.  Depending on the sutures used they will dissolve over a series of months.  Hope this helps.

Some surgeons use what I think you mean as quilting sutures or progressive tension sutures to help minimize the need for drains.  Depending upon what type of suture is used, it may take several months for them to dissolve.
