Breast fat transfer with Vaser liposuction - fat cell survival?

Question

My surgeon's website has told me that with vaser liposuction, "about 80%" of the fat cells will survive breast fat transfer (his sourced paper: Acute adipocyte viability after third-generation ultrasound-assisted liposuction), whereas with traditional liposuction only about 50% survive. This first statistic is different to what real self says (50-70%), and I'm a bit confused with what to expect. Can anyone provide any clarification?

I love VASER for strictly liposuction cases but do not use it for fat transfer.  Even at low settings, by definition, the VASER will destroy some of the fat cell.  The goal of fat transfer is to make sure as much of the transferred fat as possible survives.  Looking at your question, it doesn't make sense how VASER ultrasound would INCREASE fat graft survival.  Maybe I'm missing something but  common sense wouldn't support those statistics.

Dear rubym12,
fat viability depends a lot of surgeon technique. The fat has to be placed back into the buttocks as soon as possible so that it has a greater chance of survival. It has to be placed carefully so that not too much fat is placed in only one area. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Hello, thank you for your question. Using an energy source such as laser or ultrasound can make fat extraction easier. However, with fat transfer the bottom line if fat transfer survival long term. Using energy can harm the fat cells making their viability less. When you use ultrasound or laser, this energy can destroy the fat cells that you need to survive long term. I do not recommend using an energy device, laser or ultrasound, when doing fat transfer.

In most surgeons' hands using a variety of methods to harvest fat, the survival rate is 50-70%, especially long term being closer to 50%.  The fat cells need to be harvested with a method that does not cause them to liquify, which Vaser does.
