How can I fix my belly button 3 years after an extensive tummy tuck?

Yes you can gradually stretch your belly button with progressively larger marbles. However a slot machine belly button can be fixed with an umbilcoplasty that can widen, round out or other wise change the shape of your belly button. Having a picture of what you expect might help your doctor help you understand what can be achieved.

A belly button (umbilicus) can be revised and made to look more natural as an office procedure.  You may have it done by your previous surgeon or others in your area.

can be less than desirable and there are revisions that you could pursue to improve the appearances of yours.  The real problem must be identified (too much skin moved inwards/too much fat lateral to belly button/incomplete release of stalk/etc) to provide the recommended fix.  Discuss with your surgeon and make sure your goals can be accomplished before having more procedures.

There is a lot that can be done to improve the shape of a belly button after abdominoplasty. I do not recommend the marble trick however !  It sounds like your umbilicus is narrow and vertically stretched. Regardless of what it looks like it can most likely improve in shape by undergoing an umbilicoplasty. It is a short procedure and can be performed under local anesthesia.  Best wishes.

Your best option at this point is a revision ( umbilicoplasty) of you belly button. This typically is a very straight forward procedure and usually can be carried out in the office.Good LuckStephen M. Davis, MD, FACSGreen Hills Plastic Surgery

Depending on how things were done, you should be able to do some things to help the shape and appearance of your belly button.  It typically involves a procedure done under local and then you can do the "marble trick" or I've had success using something a little softer like ear plugs to help get a better shape.  I know it sounds funny, but it's more comfortable and works really well.  And if you're at a loud concert, it comes in handy...

The marble trick is effective in the early stages of healing, less than 1 year after surgery.  Now that it has been 3 years, however, that won't work.  You can ask your board certified plastic surgeon about umbilicoplasty, or revision of the belly button if you are unhappy with the appearance.

Since you are 3 years post op, it will not be possible to alter the shape of your belly button with a marble.  Discuss navel revision with your surgeon.  In general, this is an office procedure with very little down time.  Best wishes!
