Why do I have this crease under my belly button? (Photo)

Thank you for your question and I am sorry that your current results are not what you anticipated but you are still early in your recovery and your appearance is likely the result of a combination of asymmetric swelling to the lower abdomen and tension from the removal of excess skin.  Hang in there and allow your results time to heal and mature further, you should see steady improvement in the crease.  

At only one week out from surgery, it is way too soon to give advice on the result. At this stage, you are still early in the healing process. The final result for a tummy tuck never really judged until several months from the procedure. Typically, I will wait 3-4 months before I assess the results. Of course, it can be difficult to be patient while awaiting a result for such a long time, especially when you are excited. But, keep in mind that living human tissues are different than sculpting with plastic or sewing with cloth. Those substances are fixed and don't change much with time. Human tissues, on the other hand, stretch, spread, settle, and change as they go through the different stages of healing. This process takes time and as it proceeds, your result will change until the healing is complete.This is why plastic surgeons will always advise patience for the first few months after these procedures. In the meantime, keep in close contact with your plastic surgeon and he/she can assure you that things are proceeding in the right direction.I hope this info helps!Best of Luck, Dr. SubbioPhiladelphia/Newtown Square

Thank you for your
question and the photo. Feeling anxious to see the final results after plastic
surgery is common and completely understandable. However, at only 8 days
post-op, you’re still experiencing a significant amount of swelling. You’ll see
considerable improvement in the coming weeks. As difficult as it may be to be
patient, you really shouldn’t explore revision options until at least a few
months after surgery. As swelling subsides and the incisions heal, you’ll
likely see the crease that concerns you go away. If you’re still not satisfied
with your results 3 to 4 months after surgery, then it may be time to visit
your plastic surgeon and discuss the possibility of a revision.

It's way too early to judge the results of the procedure. The final results will evolve over a few months. Typically the crease you a mentioning is caused by a compression garments that is causing the fold. You may want to have your surgeon check the garment or binder and adjust the way you are wearing it or switch to something else that will work better.

You need to post better exposed photos to see the complete abdomen with the scar!. I guess the surgeon try to bunch centrally the excess skin of the upper incision to a shorter lower incision thus bunching occurred!
