I sat on my butt 1 week into BBL, do I still have hope for fat survival?

I recommend that my patients minimize sitting, even with a pillow, for the first two weeks. If they have to sit, it is critical that every 30 minutes or an hour that patients get up and stand for a few seconds to take the pressure off.   This reduces the chance for fat necrosis.  After 6 weeks the fat has revascularized, and you have a very good idea of your final results. Kenneth Hughes, MD, Board Certified Plastic SurgeoLos Angeles, CA

Dear fattransferpt,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. I instruct my patients not to sit for 2 solid weeks. We provide them a specialized pillow that our patients can sit on during that time. They can sleep on their stomachs or sides. Daniel Barrett, MD, MHA, MS

sitting for 30 minutes probably will not break the result. I would recommend you just do the best you can and stay off it as much as possible. I would recommend a rectangular pillow to be placed under the thighs some of these are now called the BBL pillow where there's no pressure on the buttocks. PRP has not as yet been shown to have any proven value in survival of fat cells so paying extra for that at this time may have been a waste of money. I would recommend you follow up with your doctor and address these concerns or recommend you get a second opinion from a board-certified plastic surgeon by the American Board of plastic surgery who has a lot of experience in performing this procedure.Best of luckDr Michael Gartner

There is actually NO literature to support that pressure in the early post op period causing increased fat volume loss or death. I ask my patients not to sit or apply pressure to the buttocks for 10 days because I feel that the shape stays more "round" if they stay off of it. We know that no matter what you do, you will lose ~30-50% of the fat volume that was injected over the first 3-6 months after surgery. Some PS don't even make you stay off of your buttocks after a BBL. If your surgery was done well and a large volume of pure fat was transferred, you should be just fine. 

Hello, thanks for your question and provided information as well... it will be better for you to sit on a boppy pillow for at least 6-8 weeks from the procedure. It will help your results to last. 

It is unlikely that sitting for 30 minutes would cause significant fat loss following a BBL procedure.  Be sure that any compression garment you might be wearing is fitting properly and is not getting kinked.  Check with your surgeon for further recommendations by try not to worry.  I doubt you did any damage.  Best wishes, Dr. Lepore.
