**1. Introduction**

Autologous fat grafting has been used for over a century and is still considered as a technique of choice for soft tissue replacement in Aesthetic plastic and reconstructive surgery. However, the critical point of this technique was fat graft survival. The high percentage and variable amount of fat resorption were the main disadvantages of this procedure before the use from 1997 the FAMI technique, Facial Autologous Muscular Injection [1].

Autologous fat transfer has been subject to great evolution over the last century and became very popular after the fundamental clinical studies of Y.G. Illouz [2]. The material harvested during liposuction is discarded, but the fat tissues used in fat grafting needs to be preserved and not polluted by the products used during the tumescent local anaesthesia [3]. The presence of adipose stem cells in the harvesting samples found by Patricia Zuck and her team [4] emphasised the necessity of fat preservation during the harvesting process and some changes in the technique.

JA Klein, a Californian dermatologist [5], invented the tumescent liposuction which consists of infiltrating at the fat deposit with a local anaesthetic and a vasoconstrictor diluted in a large volume of saline. This technique allowed the patients to benefit from liposuction totally by local anaesthesia, thus avoiding the risks of general anaesthesia and promoting a short recovery time.

For providing samples of fat during fat transfer which no or little contact with the lidocaine, the "Island technique" was used for decades in the first step of the FAMI technique [6, 7].

This simple method will help all practician to harvest pure fat in the syringe with less saline mixed with Lidocaine.
