Should/Does the plastic surgeon revise for free if I'm unhappy with my results 11 days out? (Photo)

This is a tough situation for all parties.  The Floating Belly Button Tuck, aka Tunneled Tummy Tuck allows for tightening of the rectus diastasis, but does not remove very much skin.  In your pre-op photos, you don't appear to have much skin redundancy.  However, after repairing the rectus diastasis, the skin excess becomes more noticeable.  I would recommend you allow your skin a few months to recover from the recent surgery before making any decisions.Then discuss the matter with your surgeon.  You may require a conversion to a full tummy tuck.  You will need to work with your surgeon to find an acceptable agreement between the two parties.  Your surgeon did carry out the agreed upon procedure.  However, sometimes the outcome does not reflect the intentions of both parties. I think a fair compromise might be for the patient to cover the cost of additional operating room and anesthesia fees, and the surgeon will cover their own fee.

Though it is still early, your concerns will likely persist.  I agree that this is likely a floated belly button tuck.  If so this is very difficult to fix later with a full tummy tuck as the belly button will not survive.  If that happens a new belly button would need to be fashioned.  'Refloating' the belly button will help with the skin laxity, but will move the belly button further down toward your pubis.  Try not to get discouraged, and give it some time.  Much of the laxity may improve.  Good luck and take care. 

Thank you for your pictures. Revision policies for up to the individual surgeon/offices. You need to discuss this policy with your surgeon.  I am sure that you could come to some reasonable middle ground about who would be responsible for fees if they revision is needed. I would give you result three months before you critically judge it.
