Buttock augmentation with autologous fat injection: is it safe?

In recent years, buttock augmentation with autologous fat injection has become an increasingly popular procedure for soft tissue augmentation and volume replacement for various body features in both reconstructive and cosmetic settings.

 

The mechanism of action of the autologous fat injection technique and its effectiveness

It is a combination of modern liposuction and then re-injection of the fat after it is purified by a special device. This device expels blood and fluids and separates them from the fat, so that the doctor obtains pure fat that is suitable for enlarging and shaping the buttocks (buttocks).

The basic steps of the process of self-fat injection in the buttocks area

Buttock augmentation with autologous fat injection is performed under general anesthesia, as local anesthesia should not be used when removing the fat in order not to damage the very sensitive fat cells and to achieve an optimal result. Depending on the amount of suction and the location of the targeted fat for suction, buttock augmentation with autologous fat injection takes about 2-4 hours.

The areas that will be filled with fat are determined, and what are the areas that need coordination in order to look the perfect appearance that gives the buttocks a prominent, beautiful and feminine shape, and he will also determine the places from which he will perform liposuction, which are mostly either in the thighs, or the sides, or the area that the doctor sees fit, and the places to which he will return the fat

 

After the fat is suctioned and purified, and the appropriate one is chosen, it is placed in tubes or syringes, and then it is implanted again in the area to be highlighted. You should keep in mind that sometimes the specialist doctor may suction much fatter than the rate that he will inject into the buttocks, because it is not normal that all the fat that will be suctioned will be injected

 

Possible health risks and side effects of buttock fat grafting

Among the common negative effects after fat grafting are: bleeding, the possibility of cellulite increases after the operation, in addition to negative reactions to anesthesia, and there is a possibility of swelling, bruising, and poor wound healing. As for the more serious complications, they include:

• Fluid buildup

After liposuction, there is an excess of fluid that can accumulate under the skin, causing swelling and bruising. To overcome this phenomenon, the doctor sometimes leaves the surgical incisions open and connects them with a tube to drain the excess fluid. The tube is removed after a day or two after the operation.

• Numbness

The patient’s feeling of numbness in the surgical area results from the liposuction process, and this feeling may last for a long time, and it may fade quickly, and the nerve located in the liposuction area may become irritated

• Body asymmetry

There are some factors that may lead to asymmetry of the body shape as a result of the uneven removal of fat from the body during the liposuction process, so the skin will show signs of ripples and lumps, due to the poor elasticity of the skin, or the inability of the skin to recover quickly. When the cannula is inserted under the skin, it may Some signs of scarring appear, all of these damages can last for a long time, or recover normally depending on the patient’s condition.

• Damage to the heart and kidneys

When liposuction is performed, the level of fluids in the body changes as a result of the level of fluids absorbed by the body and entered through injections, and the level of fluids may change in a way that affects the heart and kidneys.

• Inner holes

If the tube that is inserted into the body during liposuction reaches one of the internal organs, it may cause a perforation of one of the internal organs, and here comes the need to perform emergency surgery to treat the organ that was pierced during the surgery.

• Fat embolism

After liposuction, and as a result of fat fragmentation, part of the disintegrated fat may get stuck in a blood vessel, and may leak into the lungs or brain, causing what is known as a lipid embolus, or a state of fat embolism.

 

The preparation phase before the procedure and the necessary care after the surgery to ensure the desired results

There are several things that the patient must take into account when determining the areas from which liposuction can be performed:

• Some analyzes and medical examinations are conducted for the patient, to identify the rates of sugar, pressure, and other blood diseases, if any.
• Fat grafting is not suitable for those who suffer from certain diseases such as cardiovascular diseases or lung diseases
• Refrain from drinking alcohol, because it is considered a blood thinner, and causes bleeding during the operation, as it delays the blood clotting process.
• The patient must completely refrain from smoking, because it reduces the level of oxygen in the blood
• Stop taking medical drugs that cause blood thinners, such as aspirin, for at least a week before the operation
• Refrain from consuming any type of caffeine, so as not to affect the anesthesia process. It is difficult for a person who consumes caffeine to become anesthetized, so he must refrain from stimulants such as Arabic coffee for a week before the operation.
• Ensure to eat a healthy, balanced food, and follow a specific diet, for a week before the operation, to avoid any complications that may occur during the operation.
• Make sure to do some simple exercises a week before the operation, so that the skin is strong and flexible
