The micro-reinjection of autologous adipose tissue is an important technological advancement made possible by the use of new single-use materials whose characteristics have been certified through years of experimentation.
Microlipofilling involves a real auto-transplant of adipose cells by reinjecting fat taken from the patient themselves. Thanks to special, very small cannulas, it's possible to extract and reinject micro-particles of fat with an approximate diameter of 0.5 mm, each containing several hundred cells.
The indications in reparative and reconstructive surgery are:
- Filling of post-traumatic tissue depressions.
- Improvement of skin trophism in scar lesions of any nature, especially burns, radiodermatitis, lesions from scleroderma...
- Aesthetic indications: volumizing effect, especially in the cheek area, nasolabial folds, lips, temples...; filling and reduction of facial wrinkles.
This technique can be used alone or in combination with another cosmetic surgery treatment, especially neck lifts and facelifts.
After a thorough clinical and photographic analysis of the areas to be treated, the precise amount of adipose tissue needed and the regions for injection will be determined. The procedure is usually performed under local anesthesia and can be done either as a day surgery or in an outpatient setting.
The Surgery
In the preoperative phase, the donor areas are identified: the area below the navel, hips, the inner surface of the knees, back...
The entry points of the cannula and the extraction sites are anesthetized with Xylocaine combined with adrenaline, and then the collection of adipose tissue can begin. This collection is done manually with a 10 cc syringe and very gentle suction force; typically, 4 to 6 syringes are collected, and the adipose tissue is isolated. It is then centrifuged to separate the anesthesia fluid from the micro-islands of adipose tissue.
The re-injection can begin after local anesthesia and the creation of access points through which micro-cannulas will be introduced to inject the adipose tissue in all directions and on all planes. The micro-islands of adipose tissue will act as grafts and remain stable over time, improving the quality of the skin.
In the post-operative course, there is no pain, minimal swelling, and usually only a few bruises appear. The result stabilizes after 2 months, and follow-up appointments will be scheduled at 2 and 6 months after the procedure. Micro-reinjection of autologous adipose tissue is a real surgical intervention. It will be necessary to ensure that there are no contraindications for the use of local anesthesia, and the risk of infection appears to be minimal. Over-correction and the injection of an excessive volume of adipose tissue should be avoided. In summary, micro-reinjection of autologous adipose tissue is a new technique made possible by the use of highly efficient cannulas that have the advantage of being single-use.
