The process of fat injection for soft tissue augmentation has not been standardized as compared to liposuction. The process of collecting, cleansing and injecting fat, as well as the effective use of fat transplantation varies among physicians. Here, I would like to present my cases as well as those of Ichida who lectured on the methods of fat transplantation at 7th Korean esthetic surgery Symposium in Nov.1998 in Seoul.
  As liposuction has developed over the last two decades, more thoughts have been given to the use of fat over synthetic materials. Although there are some drawbacks to the use of fat, such as inconsistency in results (resorption), the benefits from the absence of rejection and the low cost make it attractive. I have obtained good results in soft tissue augmentation using the following technique. The fat is manually harvested using a 10 cc syringe with a 3mm cannula from the donor site. The tissue is then irrigated in a stainless steel filter with saline solution 2-3 times to remove the blood. The fat is then collected with a 1cc syringe and 18G needle. The syrings is inserted at the recipient site. As the needle is withdrawn, the fat is injected in 0.05 ml increments (20 each) along the exit path. the process is repeated in multiple layers until the soft tissue is augmented. This method is less aggressive, more precise than bolus injection, and provides a much higher survival rate of injected fat tissue.
