Should do ultrasonic cavitation on my stomach, flanks & back before surgery to tighten skin? (Photos)

Unfortunately, the combination of your skin quality and the amount of tissue that would be removed would leave you with apparent excess of skin that will not be ‘tightened’ by any skin tightening modality, with the exception of skin excision, i.e. a tummy tuck. There is a saying ‘if all you have is a hammer, everything looks like a nail’. That gets to the core of the issue you may be having: if the surgeon you are using can’t do a tummy tuck, he’s/she’s not a board certified plastic surgeon and he/she can’t give you the appropriate evaluation and recommendations. In your case, it’s a tummy tuck. You don’t have to heed my words, but I can tell you that a smooth, attractive abdomen will not be yours after the cavitation liposuction alone.
