Are the results of ultrasound cavitation permanent? Is it possible to reverse them?

While this procedure isn't textbook "reversible" there are options available that can provide you with great results. Some options include a fat transfer or Sculptra injections. I suggest waiting a minimum of 3 months post op and including lymphatic massages as a part of your post op care routine as the results may be better over time. See an expert. Best, Dr. Emer.

merano.  Sorry you are having these issues, however it is difficult to evaluate without photographs or physical examination. Generally speaking, traditional Liposuction is the gold standard for fat removal and body contouring. In your case, I recommend waiting at least three months for all healing to occur, and then seek the advice of a board-certified plastic surgeon in your area. Best of luck.

Without in person examination and seeing the before treatment photos to compare the results, none of use, responding MDs can offer much guidance. Usually after 3 months the results are finalized. Reversal could most likely only be done with fat grafting or injections of Sculptra or Rejuvenate (stored allograft fat) syringes - this is very expensive but can improve deficiencies.
