1, operation flow
1, first mark the range of depression and the suction range of fat donor area.
2. According to the size of the depression, determine the size of the suction range and the size of the suction.
3. The fat donor area is anesthetized by local infiltration. Inhale 1ml saline in the syringe with a 5ml syringe, and aspirate with the needle of 16 syringe.
4. The small incision on the edge of the upper eyelid suction area filled with autologous fat is (1 mm ~ 2 mm). After the needle pierces the skin through the incision, the syringe is pumped into negative pressure and kept negative pressure.
5. Pinch the skin and pull it back and forth in the subcutaneous fat layer. At this time, red and yellow blood lipid particles can be inhaled in the syringe, and generally 3 ml to 5 ml of blood lipid can be sucked out.
6. Autologous fat fills the depression of the upper eyelid. Rinse blood fat repeatedly with normal saline through the syringe to wash away blood cells, leaving pure yellowish fat particles in the syringe.
7. Suck with another syringe and several syringes as above until enough fat particles are estimated.
8. Choose a hidden incision (65438±0mm ~ 2mm) at the edge of eyelid depression, pierce the needle into the subcutaneous through the incision, and pump the fat particles into the subcutaneous through the incision, and inject evenly. The injection amount should exceed about 50% of the required filling amount.
9. Autologous fat is used to fill the depression of the upper eyelid and suture the incision with 5/0 silk thread.
2. Introduction to Surgery
Eyelid depression is caused by fat atrophy around the orbit, skin inelastic, natural aging process, facial trauma and complications of previous periorbital surgery, which can lead to eyelid skin retraction and unpleasant wrinkles. People with less fat around the orbit will look listless and even fierce, and there may be many folds in the upper eyelid. For the sake of social image and beauty, there are many ways to improve the depression of the upper eyelid, such as upper eyelid reduction and then.
Indications of eyelid depression filled with autologous fat: it is suitable for senile eyelid depression, traumatic eyelid depression, double eyelid incision or eyelid depression caused by excessive orbital fat removal during pouch surgery.
3. Precautions after operation
1. The absorption rate of fat injected into the lower eyelid depression is about 60%, which should exceed 50% of the required amount during operation. After absorption, depression can basically be corrected. If the effect is not good, repeat injection after 3 ~ 6 months.
2. Sucking fat should be done under the skin, not too deep, and it is not allowed to insert a long needle into the abdominal cavity by mistake. Special attention should be paid to aseptic operation in liposuction and injection. In order to avoid infection leading to surgical failure.
3. Avoid touching water and squeezing with your hands within one week after operation, and abstain from stimulating foods such as seafood, spicy food, beef and mutton, tobacco and alcohol within one week.
4. Pay attention to hygiene or follow the doctor's advice, which will help to obtain better autologous fat filling effect.
