By the term lipostructure it includes the removal of a certain amount of fat from certain areas of the body where this is present in excess and its transplantation, once suitably purified, in other areas of the face (but also of the body) in order to correct wrinkles, furrows or scar depressions. This surgical technique established use for decades now is widespread and commonly practiced by plastic surgeons in all parts of the world. The more classical donor sites include the abdomen, buttocks and thighs for obvious reasons distribution of adipose tissue in the human body.

Depending on the needs it is intuitive that this type of intervention is of course matched to the intervention of liposuction or liposculpture which has the purpose of removing localized fat deposits in excess and to sculpt certain aspects of the body behind the patient’s specific request. The sampling and purification technique must be performed rigorously using atraumatic cannulas that damage fewer fat cells possible if the fat cells to be transplanted.

The presence of stem cells in lipoaspirate (ASC adipose derived stem cells) has been well documented in scientific studies and esisitono variety of methodologies to concentrate this type of “regenerating” cells in the fatty material. The evolution of lipofilling (English term which is defined such technique) is based on the adipose tissue preparation techniques to be injected which is first filtered and then centrifuged to remove the unnecessary component (oil, serum and blood) from lipoaspirates trying to concentrate the cellular component. In the injection we have instead witnessed a refinement of techniques iniezieno (nano fat grafts and micro lipofilling) techniques in which microcannulas with 0.7, 0.8 or 0.9 mm are unable to infiltrate the eyelid and orbital area, the contour of the mouth, the region zygomatic and nose genieni grooves minimizing complications such as the formation of nodules, granulomas, and in spite of irregularities, in those areas the epidermal layer is particularly thin.

The transplanted cells play in this way their action bringing volume and renovating in a natural way the treated fabrics. The birth of this technique is done in reconstructive surgery where it is widely used to treat outcomes of burns, depressed scars and disfiguration of regions such as breast reconstructed after mastectomy or depressions created in the course of previous liposuction procedures performed too casually or aggressively. From here has been gradually also used in cosmetic surgery of the body to increase the buttocks, enlarge or reconstruct the breast up to also be used on the male and female genitals are the most sensitive areas to be treated. The intervention takes place in almost all cases and under local anesthesia in each case with anesthesia care. The result is stable over time because the transplanted cells acquire a new own life in the tissue where they were inoculated diversifying through the action of specific growth factors. The advantage compared to the common hyaluronic acid-based fillers is that the results are more stable in time and that the material to be injected is abundantly available in the human body.
