Preventing Belly Button Closure After Tummy Tuck?

Hi there-
It looks to me like you have a yeast infection around your belly button...
It would be impossible to tell without an examination, but I would recommend you visit your surgeon and ask if some anti-fungal therapy would be appropriate.
As far as keeping your belly button looking like a belly button, I try a glass marble.

There may be many reasons for the rash. One is a mild yeast infection and the other is a reaction to bacitracin ointment or the metal as stated. If approved by your surgeon, I would suggest using a mild steroid cream (if not infected) or an antifungal cream. I would allow this to settle. Glass marbles can be found at a craft's store. Occasionally I prefer glass beads because a small string can be placed which makes them easier to retrieve or remove once in place. Sterilize or cleanse the bead before each and every placement.

You can also try placing some gauze in the belly button to keep it open; may of us use Xeroform gauze after surgery for this purpose. Check with your local pharmacy as a prescription may be required for this depending upon your state's regulations.
If you do need a revision, this can usually be done under local anesthesia in the office. Good luck.
