What is the survival rate of frozen fat cells for a fat transfer ? Is frozen fat reliable in a fat transfer or is the survival rate of the frozen fat cells more likely to be reabsorbed due to not being fresh?

Answer: Transfer frozen fat cells? I think it would be a waste of time and money to try this. Have your transfer done at time of harvesting. If you want more transfer later, then hold some donor site areas to be liposuctioned at that later date. Good luck.

Answer: Frozen fat transfer Nadia, It is difficult to preserve tissue by freezing it as water normally forms sharp ice crystals and expands which normally kills cells. Some special techniques are used to preserve certain tissue, like sperm or eggs, but freezing isn't used for most transferred tissues. That is one of the reasons transplanting an organ is so complicated. Some studies have shown that fat grafts cooled to just ABOVE freezing can survive for weeks, but even if the survival rate is close to fresh fat it will never be better than fresh fat. That means the more important question is why would you ever use frozen fat cells? An experienced surgeon using a time-tested technique should have a consistent survival rate and be able to achieve good volume restoration at the initial procedure. If more fat is needed at a latter date it should be years down the road, and a second harvest of fresh fat cells seems more practical than trying to store some for this possibility. -Dr. Rolfes
