How would this scar/overhang be fixed and will I need another full tummy tuck? (Photos)

First of all, I would ask your gynecologist why in the world he or she didn’t just use your previous incision. I cannot think of any good reason for this, and it put the skin between the incisions at risk for necrosis. Now, you have these two scars on each side and the only way to really surgically correct this is to remove the skin and the remainder of an ellipse of skin further out to the side laterally. This would result in a longer, but single, scar.  

Hello.
Great question. Thank you for your question. Based on your images, it appears you may benefit from a full tummy tuck procedure to aid in your bulge, bely button and scar. Please visit a board certified plastic surgeon for a detailed surgical plan to achieve your desired results. 

Dear Stainless,
based on your photos, it looks like you would need scar revision in order to get better results. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

First, you should call your gynecologist for not using the pre-existing scar versus making a new one...ludicrous and dangerous to the skin in between the two scars!You may do a revision abdominoplasty and combine the two scars into one, or just do liposuction of the lower abdomen and flatten the bulges.Dr T

Your OB/GYN should not have made a second parallel incision. This should never be done in surgery and creates something called a watershed zone. The skin between the two parallel incisions can die creating a large wound that can be difficult to heal. It’s Also not very attractive.Most likely your OB/GYN cut through all the muscle tightening stitches below your belly button and did not replace them correctly and now your lower abdomen bulges and that’s why you have the appearance that you do.The only way to correct this is most likely to redo the entire tummy tuck though it’s possible you will not need muscle tightening from above the bellybutton.Best, Mats Hagstrom MD
