With a tummy tuck, are progressive tension sutures permanent or dissolvable?

No sutures really need to be permanent in a Tummy Tuck and definitely not progressive tension sutures. Permanent sutures are occasionally used for muscle tightening known as plication however I personally avoid permanent sutures. The reason to avoid permanent buried sutures is the risk of getting that suture infected and the spitting of the suture requiring additional surgery to remove it.

Progressive tension sutures are typically temporary and dissolve in a few months, therefore, should not be noticeable after surgery. Ask your surgeon if you are uncertain.
