Is my current scar from myomectomy too low to be removed during upcoming hysterectomy/ tummy tuck surgery? (Photo)

You should get an excellent result from a full tummy tuck. The abdominoplasty incision will remove your current scar. Good luck with your surgery.

It should be possible to make it to the existing scar when performing the tummy tuck.  The necessity of a vertical scar would be determined at surgery.

These are excellent questions: 1) Yes,
we can incise below the myomectomy scar and excise it with the abdominoplasty,
and it is unlikely that you will have a vertical scar where your former belly
button was due to the amount of left we will get from the mons, groin and upper
thigh region and the upper abdominal skin laxity. 2) Yes, you will have
beneficial lifting and tightening of the mons, groin and upper thigh region!
The crease next to the mons will also go away. 3) The area you are pinching on
the side of your hip is the front margin of where we suction for muffin top,
but you have very little fat in this region. But on your backside, you will
benefit from liposuction. 4) Yes, enough skin for a full tummy tuck! 5) It
looks like you may have a small hernia in the upper part of your belly button,
which can be fixed at the time of the tummy tuck.

Don't forget that your internal girdle will be tightened with repair of you diastasis recti
resulting in a stronger core and flatter tummy.

Make sure to do your homework finding a plastic surgeon, ask for before and
after photos and focus on the incision, which should be low under the bikini
line and look at the new belly button to make sure they look pretty &
natural.

Good luck and thanks for sharing.
