My appendix scar: would lipo help me to have a flat stomach? (Photos)

Thanks for your question and posting photos. 
When patients have contracted scars on the abdomen, it can lead to the surrounding skin looking bulging and uneven. Fortunately for an appendix scar, the entire scar should usually be able to be removed with a tummy tuck including the surrounding skin which makes the bulging. 
While liposuction can improve the contour somewhat by creating a more even projection, the results are more limited compared to a tummy tuck which can offer the best treatment of these areas. 
Seeing a plastic surgeon will allow you to get a detailed examination and a personalized treatment recommendation.

Dear Milanmom,
So, liposuction by itself would not give you a "flat stomach".  You definitely would need some skin excision, specifically to address the indented appy scar.  Also, it would probably benefit you to lose 5-10 pounds prior to the surgery.  Good luck and hope this helps!
