During a C section no extra skin is removed for aesthetic purposes. A tummy tuck is done for cosmetic reasons, an incision is made along the top of your pubes (mini tummy tuck) or from one hip to the other (tummy tuck) or from one side of your torso to the next (extended tummy tuck) or all the way around your lower torso (extended tummy tuck). the amount of excess skin you have will determine which one you require. the belly button is replaced (not necessary with a mini TT) and in addition to a tummy tuck you can have muscle repair (good for those with children) where the surgeon tightens the unlying mucles to make the abs look flatter/better. This procedure is usually performed with some form of liposuction. hope this helps!
