Thank you for your question. The belly button incision is probably the part of a tummy tuck that has the most variation among Plastic Surgeons. Each surgeon has found their own best way of performing this part of the procedure, known as the umbilical transposition. I place a deep layer of dissolvable stitches below the skin, and then I place very very small nonabsorbable stitches externally in the skin, which I remove in my office at 5-7 days. If you talked to 10 different Plastic Surgeons, you would probably hear 10 different ways of doing this part of the surgery. The incision will continue to look better and better each day. At six days, it is still very early for you. Be patient. You will likely be happy once you give it more time. If it is still unacceptable to you after 3-4 weeks, you should at least bring it up to your surgeon. He or she should be aware of this, and they can potentially revise it in a few months. Best of luck!
