What Is an Autologous Fat Transfer?

Autologous fat transplantation is to suck out the excess fat in the waist, abdomen, thighs and other parts of the body. After cutting-edge green centrifugation, purification and purification, select complete fat cell particles to improve the survival rate of fat cells. Adopt fine combined injection technology, multi-level Perform facial filling / removal / shaping of temples, apple muscles, cheeks, etc. at multiple points.

Autologous fat transplantation

1. Autologous fat transplantation is its own fat particles. As its own tissue, its biological characteristics are far better than any prosthetic material, so it is non-toxic and harmless to the beauty seeker itself, and it will not produce an immune response and Rejection.

2. Autologous fat transplantation will not cause changes in the endocrine environment of the human body, and will not produce the breast itself.

Fat grafts have a lower survival rate (generally reported as 30%), and sometimes require a "little and multiple" approach and overcorrection. Due to the unstable treatment effect, the widespread use of this surgical method has been limited.

Autologous fat transplantation has a wide range of indications: dysplasia of facial soft tissues, depressions in the palate, temporal, frontal, and orbital areas, depressions caused by facial surgery or trauma, the upper lip is too thin or too short in humans, the nasolabial sulcus is too deep, and the ear lobe Minor etc

Used for congenital mammary dysplasia, breast atrophy after breastfeeding, asymmetry of bilateral breast sizes, and deformed nipples;

Used for depression after liposuction, and depression of other soft tissues in the body, such as hip, thigh, calf flexion, etc .;

Soft tissue atrophy of the hand (commonly known as chicken paw hand);

Remodeling of genitals, such as thickening penis, vaginal relaxation, atrophy, etc.

The technique of autologous fat transplantation facial modification is to collect stem cell-rich fat particles from the excess parts of the patient's body fat, purify them through specific treatment, and then use three-dimensional three-dimensional injection to transplant all levels of the face. The entire process is completed with a very thin catheter needle. Compared with the traditional surgery for skin peeling, autograft facial modification is safer, does not require surgery, leaves no scars, no foreign bodies, and is not painful.

And autologous fat transplantation has undergone more than 100 years of scientific research and clinical certification; so far, there are many more mature autologous fat transplantation technologies in the world, such as Coleman technology in the United States, FAMI technology in Spain, and domestic FAAS technology.

1. After being filled with fat, it is absorbed to a certain degree. In order to ensure the best results, another operation is needed;

2. The fat distribution after filling is uneven, and massage is required to make the fat cells as evenly distributed as possible;

3. Too much fat or too concentrated injection, a large amount of fat accumulation will cause fat necrosis, dissolution and absorption due to insufficient blood supply, and it is easy to cause infection, resulting in sequelae such as fibrosis or calcification and fat necrosis.

Filling defects with autologous fat transplantation has become a new dawn. Although it is convenient and non-exclusive, it still has its limitations:

(1) The blood circulation in the filling area must be good, and there should not be too much scar tissue, so as not to affect the survival of the transplanted fat cells;

(2) The fat suction technology should be gentle, the suction pressure should not be too high, to avoid damaging the fat cells, and the granular fat cells can only be injected and transplanted after screening and purification;

(3) The amount of injection at a single point should not be too much, otherwise it will only affect the growth of microvessels into fat cells and reduce the number of survival;

(4) At present, the best autologous fat transplantation technology will be absorbed by 50-75% after one year, so it is recommended to inject an additional 2-3 times to achieve the best results.

1. Technical principle:

Autologous fat transplantation to remove the nasolabial sulcus is to absorb fat from the body's own fat-rich parts, such as the abdomen, buttocks, thighs, etc., by using liposuction technology, after special treatment into pure fat particles, the injection is implanted into the nasolabial sulcus. Wrinkles to fill and eliminate nasolabial folds.

2. Adapt to the crowd and contraindications

Adapt to the crowd: adapt to various degrees of nasolabial sulcus, according to the degree of nasolabial sulcus, the amount of fat filled is different.

Contraindications

a. Those with important organic lesions.

b. Those with scar constitution.

c. People with bleeding tendency.

d. Local skin condition.

e. People with mental illness.

3.Technical methods

Liposuction: Use swelling and anesthesia techniques in obese areas such as waist, abdomen, thighs, buttocks, and use liposuction equipment to suck the subcutaneous fat required for transplantation.

Fat particle purification: The fat particles sucked are processed by fat purification technology to extract the fat particles required for injection.

Fat injection: Inject the purified fat granules into the nasolabial folds, and then massage and shape with appropriate pressure bandaging.

Due to the low survival rate of autologous fat transplantation, if the filling effect is not satisfactory, a second injection filling can be performed after 3 months.

4. Material: autologous fat particles

5. Risks and complications

Infection Infection usually occurs 5-7 days after surgery. The infection is localized with redness, swelling and hot pain. In severe cases, local skin flushing and bruising or pinholes do not heal and pus. When symptoms of infection occur, go to the hospital in time.

Hematoma may form during liposuction and injection. Under normal circumstances, severe hematomas do not occur.

Skin ecchymosis is caused by blood exudation. Skin ecchymosis usually does not require special treatment and can be resolved within 2-3 weeks.

Skin necrosis mostly occurs in the liposuction area. If skin necrosis occurs, seek medical treatment as soon as possible to reduce the occurrence of obvious scars.

Local skin unevenness is generally 3-6 months after surgery. The body itself can be adjusted, and most of it can be restored. If there is still unevenness, you need to go to the hospital for correction.

Lipoma formation Granular fat injected subcutaneously can accumulate or stimulate host cells to proliferate into lipomas. After the formation, only removal to the hospital by removal.

Fat liquefaction injected too much into adipose tissue, or the adipose tissue naturally aggregated into blocks after injection, resulting in the injected fat failing to survive, resulting in fat necrosis and liquefaction. Fat liquefaction occurs, you need to go to the hospital to puncture and extract the liquid, or drain under negative pressure.

6. Recovery time

Autologous fat particle transplantation and wrinkle removal generally does not require hospitalization. Swelling can be reduced 1-2 weeks after surgery, and normal work and life can be achieved. Due to the absorption of fat in injection transplantation, if the filling effect of one injection is not satisfactory, 2-3 injection transplants may be required.

7, matters needing attention

Non-steroidal anti-inflammatory drugs such as aspirin should be discontinued two weeks before surgery; smokers should be abstained two weeks before surgery; female patients should avoid menstruation during surgery.

Take a bath before surgery and keep it clean.

Minimize activities after surgery to facilitate recovery and swelling, but without bed rest;

Use elastic bandages as much as possible within half a month after surgery to avoid hematoma and help tighten the skin.
