Liposuction is not a treatment for obesity, but rather it is designed to correct the persistence of fatty tissue that cannot be removed under regular dietary regimens. The technique consists essentially of the aspiration of the fat of an area determined by means of the introduction of a blunt cannula that is connected to a machine of high emptiness (aspirator).
One of the important advantages of this technique is that the aspiration is being performed using a small incision that can oscillate from 2 to 8 millimeters in length, to insert the cannula. As the incision does not need to be located in the exact place of aspiration but it can be located at a certain distance, it allows to hide the small scar in a little visible zone. The aspiration of the fat is made making numerous tunnels with the cannula in the pre-marked areas.
It is important to be able to make a suitable liposuction so that the skin has a good elasticity so that it can adapt to the fatty tissue reduction without external signs of flaccidity.
By means of the liposuction technique fat of different corporal regions can be aspirated: hips, thighs, knees, ankles, arms, abdomen, face, etc. in some occasions the technique is made altogether with other interventions like mamoplasty, abdominoplasty, etc.
Liposuction is usually performed under general anesthesia although it can be done under local anesthesia with sedation if it is a small area. After the intervention, it is important to use a sticky elastic bandage or a compressive strip on the zone that has been treated.
It is normal that bruises appear in the area of liposuction. The fatty tissue tends to swell up by the surgical trauma and usually takes a considerable time in recovering the previous volume. For that reason, the results of a liposuction are not due to evaluate before a minimum of three months of the intervention. If the skin elasticity presents itself with irregularities or small depressions where the suction has been performed, it might be necessary to inject fat or perform local treatments and massages.
Sometimes the patients can present excess fatty tissue in some areas and lack in others. In this case injection of his own tissue can be placed creating harmony in the patients figure.
