What Is A Blow Out Deformity?
Fat cell transfer requires the cells to become vascularized otherwise face death. When a fat cell dies, it can become prone to infection. If there is a small volume of fat cells that die, then the body will be able to remove them.
However, if there is a large volume of fat cells that die in one region, then they cannot be reabsorbed, and will subsequently create a lake of dead fat cells.
