Is this a typical outcome of an extended tummy tuck with mons lift and SAL epigastric flanks and abdomen? (Photo)

Your perception is correct. The remedy is a secondary abdominoplasty to removal additional tissue. Some surgeons flex the operating table to maximize skin removal, while keeping the scar level low and well-concealed. Fortunately you can still get the outcome you want. Just need another operation.

As I mentioned in your previous post, This is far a good result and obviously not desirable. It's not malpractice material, and it every bit fixable so that you can obtain a far different result.

From the photos it appears you would have an improved result from a revision. There is still excess fat and skin that can be excised and further contouring performed in order to achieve better results. See a board certified plastic surgeon near you to learn more.
