Re-centering Belly Button After Tummy Tuck?

If the navel is off center by only a quarter of an inch, it can be reposition with local anesthesia.  There are several ways to do it but tightening the fascia on the opposite side of the deviation can move it laterally without any further scarring on the abdominal wall.  A second option is to make a lateral skin incision and pull it towards the midline by way of skin tension.  The navel may, however, have a slanted funnel.

Numerous issues surround an off centered umbilicus and it is most likely due to an off centered umbilicus pror to surgery. Commonly this is associated with a minor scoliosis. Once it is placed, options for correction include tightening the muscle to "pull" it over to the other side or sliding it throught the skin which will leave a scar on one side.

The position of the belly button during abdominoplasty is determined by the umbilical stalk. In most cases, the position of the umbilicus on the abdominal wall is not changed during a tummy tuck procedure.
Interestingly, a study performed a few years ago determined that in most patients, the position of the umbilicus is actually off center. Discuss this study with your plastic surgeon as it was published recently in PRS journal.
In answering your question, there are several ways to mobilize the umbilicus if it is off center. These should be discussed in the context of your physical examination.
