Why don’t doctors use ultrasound to minimise risk during a Brazilian butt lift?

There are some surgeons using ultrasound to evaluate depth of injection during fat grafting this is not mainstream, and may never become widely used. There are some new cannulas being developed to differentiate between injecting into fat and muscle, but these are in the early stages. For experienced injectors, an ultrasound is not required to ensure safe depth of injection, which is subcutaneous.Watch this brief video for more information.Best wishes,Dr.Bruno

Thank you for your question.
The problem with intra muscular and intra vascular injections could be solved with use of intra operative ultrasound as you have suggested. There are however practical problems with this approach at this time. A surgeon who is well aware of the anatomy and stays above the muscle will avoid this problem without additional modalities. In the future, however, intra operative ultrasound may become a useful addition to the procedure. All The Best !

During a Brazilian Butt Lift operation, using ultrasound to make sure that you do not inject the fat too far is an idea that has practical limitations, as it would have to be in real time to really safeguard this. It's important that the surgeon plans the operation anatomically to ensure they don't go deep under the muscle.
