What are my options for revision, tummy tuck, etc?

A tummy tuck can be done for you and will remove part of he old scar.  However there will be a new scar across the lower abdomen.  I think it will improve the appearance considerably but only you can determine if it is worth the additional scar involved.

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  It would be helpful to view your entire abdomen.  You may be a candidate for a tummy tuck, which could completely remove this vertical scar.   Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most
important aspect is to find a surgeon you are comfortable with. I recommend
that you seek consultation with a qualified board-certified plastic surgeon who
can evaluate you in person.
Best wishes and good luck.

You could consider scar revision or skin removal through a horizontal scar.Kenneth Hughes, MDLos Angeles, CA

Hello,Thank you for your question and photo. Your scar could likely be revised to appear smoother and thinner. I recommend that you see a board certified plastic surgeon in person for assessment and to discuss options.All the best 

Hello,Your scar is noticeable because it is adherent to the muscle wall, giving a deep depression.  This can be made flat, with a much finer scar. Go visit a few ABPS certified/ASAPS member surgeons who specialize in body contouring. Best of luck!
