BodyTite for Loose Flanks? (Photo)

I have went from 33% body fat to 14.5% body fat in the last two years. I had abdominal liposuction and this surgeon let me know he got as close to the skin as possible to heat it so it would retract. From the results this sounds plausible. This surgeon retired. I went to a new surgeon at the same practice to have my flanks lipo'd but the skin did not retract in the same manner as the abdominals. I've been advised that I may need a torsoplasty or could try BodyTite. Thoughts?
