Autologous fat filling is a common plastic surgery method. Now more and more people are beginning to accept autologous fat filling. Autologous fat filling is actually to transfer local fat on the body to areas with less fat. Although It is said that autologous fat filling is a minor surgery, but many people are still afraid of it. Is autologous fat filling safe? Is autologous fat filling risky?
1. Is autologous fat filling safe?
Autologous fat filling is not absolutely safe.
When performing autologous fat filling, there are very strict requirements on the level of the doctor and the surgical environment, so that the safety of autologous fat filling can be relatively guaranteed.
2. How to ensure safety
Autologous fat filling first requires a doctor to have a professional and skilled technical level. The doctor must be very familiar with the facial structure system to avoid damage to nerves, blood vessels and muscles. , In addition, the amount of liposuction must be accurately controlled.
Furthermore, autologous fat filling surgery must be performed in a sterile environment to ensure the sterility of the fat re-injected into the human body and avoid skin infection and inflammation in the recipient.
3. Risks of autologous fat filling
(1) Infection
Under normal circumstances, there will be no rejection of autologous fat filling. However, if you do not pay attention to disinfection during the operation, it will easily lead to the risk of infection. If the patient's surgical site is already infected, it will also lead to postoperative infection. Generally, infection will appear 5 to 7 days after the operation. When this happens, prompt medical treatment is required.
(2) Postoperative blood lipids
Human facial blood vessels and nerves are densely distributed. If the doctor is not skilled in liposuction, it is easy to cause damage to the patient's skin. Cause subcutaneous bleeding.
If the facial subcutaneous tissue or small blood vessels in other parts are injured during fat injection, or the patient has a coagulation disorder, bleeding and hematoma may occur after autologous fat filling.
(3) Skin ecchymosis
Autologous fat filling requires very high technical skills from the doctor. If a large local wound is formed during the liposuction process, the tissue cavity will Excessive blood leakage will occur and skin ecchymosis will also form.
(4) Skin itching
When performing autologous fat filling, if the disinfection is not thorough, the patient may come into contact with surgical instruments contaminated with bacteria or receive the surgery in a bacterial environment. Surgery may cause skin infection and inflammation, leading to skin itching.
(5) Subcutaneous effusion
Autologous fat filling may also lead to subcutaneous effusion, which is caused by poor venous return. This generally occurs. In the lower limbs, fluid accumulation occurs about 10-20 days after surgery. Once this occurs, the fluid should be drained out in time at the hospital.
(6) Formation of lipoma
The reason why lipoma is formed after autologous fat filling is mainly due to the accumulation of granular fat injected subcutaneously, or the adipocytes stimulating the proliferation of host cells. . Although this risk is relatively rare, the recipient must be cautious.
(7) Fat movement
Improper post-operative care for autologous fat filling and excessive squeezing of the fat injection area can easily lead to the risk of fat movement. Therefore, autologous fat filling must not only choose It is carried out in a regular hospital, and postoperative care must be carried out in accordance with the doctor's instructions.
(8) Fat liquefaction
If too much autologous fat is injected at one time, or the fat tissue naturally gathers into lumps after fat injection, causing the fat to fail to survive, it is easy to cause fat necrosis or Liquefaction, if this phenomenon occurs, you must go to the hospital promptly for puncture to extract the liquid, or negative pressure drainage to suppress the harmful side effects of autologous fat filling.
(9)Skin necrosis
If the doctor’s method is too violent when performing liposuction, it will easily lead to the risk of local skin necrosis, so you want to avoid doing autologous fat filling When such risks arise, it is best to go to a professional public plastic surgery hospital for surgery. Once the risk of skin necrosis occurs, seek medical treatment as soon as possible.
4. Precautions after surgery
1. 2 to 3 days after autologous fat filling is the peak period of swelling, so put on a shaping garment immediately after liposuction, which can help Control swelling.
2. When filling with autologous fat, liposuction will cause local wounds on the skin. Before the sutures are removed from the wound, do not let the skin at the liposuction site touch water, because bacteria in the water can easily enter the skin along the wound. , leading to wound inflammation and infection.
3. In the initial stage of autologous fat filling surgery, the affected area will appear swelling, soreness, etc., and some may even have congestion and bruises. This is because the small blood vessels in the skin are trapped by the skin during liposuction. Most bruises will slowly disappear and recover within about a week, so you should get enough rest during this time to avoid postoperative bleeding.
5. How soon can you wash your face?
Generally, you can wash your face after 7 days of autologous fat filling. You cannot wash your face within 7 days, and you cannot let the wound get wet.
However, this also depends on the patient’s physical constitution and the recovery situation after autologous fat filling. Different physical constitutions require different recovery times, and the specific time for face washing is also different.
