Autologous fat grafting of lower eyelid

Autologous fat grafting of lower eyelid

The lower eyelid is an important part of the eye, also known as the eye socket. If the lower eyelid is not good-looking, for example, if it is sunken, it will have a certain impact on the image of the eye and even the overall appearance. In order to solve the problem of sunken lower eyelids, autologous fat can be used to fill the lower eyelids. Below, I will explain this method in detail.

1. Is autologous fat filling for lower eyelid depression effective?

Sunken lower eyelids are not common. It may be due to age or excessive fat removed during eye bag removal surgery. Sunken lower eyelids give people a feeling of oldness and fatigue, and patients need surgery. For sunken lower eyelids, the most common method currently is to use autologous fat injection to fill them. The filling material is taken from the body, there will be no rejection reaction, it is safe and reliable, and the effect is natural.

2. Autologous fat filling lower eyelid surgery process

First, mark the extent of the depression and the aspiration range of the fat donor area. The fat donor area is generally chosen near the navel in the lower abdomen. According to the size of the depression, determine the minimum suction range and the amount of suction. The fat donor area is anesthetized locally with local infiltration, and suction is performed using a 5ml syringe and a No. 16 syringe needle. When suctioning, first draw 1ml of normal saline into the syringe. The saline can act as a buffer during suction, thus reducing bleeding. Make a small incision (1mm to 2mm long) at the edge of the suction area. After the needle pierces the skin through the incision, draw the syringe into negative pressure and maintain it. Pinch the skin and pull back and forth in the subcutaneous fat layer. At this time, light reddish-yellow blood lipid particles can be sucked into the syringe. Generally, 3ml to 5ml of blood lipids can be aspirated.

Then, based on the different densities of adipose tissue and saline, another syringe is used to perform suction in the same way. Repeatedly use several syringes to aspirate until the estimated amount of fat particles is sufficient. Choose a more hidden place on the edge of the depression (1mm to 2mm) and make an incision. The needle penetrates into the subcutaneous tissue through the incision and the fat particles are evenly injected into the skin. The injection volume should exceed about 50% of the required filling volume. Finally, the incision was sutured with 5/0 silk sutures and removed after 6 days. Fat absorption will be obvious within 1 to 2 weeks and basically completed after 1 month, which can relieve the problem of sunken lower eyelids.

3. Notes

It should be noted that part of the autologous fat will be absorbed. If some patients do not achieve satisfactory results after surgery, they can be injected again after 3-6 months. Fat suction should be performed in the subcutaneous layer, not too deep, and long needles should not be accidentally inserted into the abdominal cavity. When performing liposuction and injection, special attention should be paid to aseptic operation to avoid infection leading to surgical failure.

Autologous fat filling technology is the key to solving the problem of sunken eye bags, but it is relatively difficult. Autologous fat filling of the lower eyelid requires the expert to have rich clinical experience and be able to accurately and evenly inject the right amount of fat to ensure good results of the operation.
