The nasolabial fold, commonly known as the "legal pattern", refers to the fold from the sides of the nose to the corner of the mouth, which is the dividing line between the cheek and the upper lip. Anatomically, it is located outside the rim of the orbicularis muscle and the upper lip muscle and the iliac muscle. There are three starting points for lifting the upper lip muscle, starting from the bottom of the nose, the lower jaw and the zygomatic arch, ending at the mouth. The occurrence of many facial expressions requires the contraction of these muscles, which are initiated by changes in the shape of the nasolabial fold. Repeated movement of these muscles causes the nasolabial fold to gradually deepen with age.

The injection of autologous fat granules into the nasolabial fold is a fat that is rich in the body's own fat, such as the abdomen, buttocks, thighs, etc., is sucked out by liposuction technique, and after special treatment into pure fat granules, the injection is implanted into the nasolabial lip. Ditch folds to achieve the purpose of filling the nasolabial fold.

Therapeutic effect: long-term maintenance Suitable for people: people with legal patterns Recovery time: 1-2 weeks

Indication

Adapted to various degrees of nasolabial fold, depending on the degree of nasolabial fold, the amount of fat filled is different.

Contraindications

1. Those with important organic lesions.

2, scar body.

3, there are bleeding tendency.

4, local skin has a disease.

5. Psychiatric patients.

Preoperative preparation

1. Autologous fat injection and filling of the law before the physical examination to ensure that your body is healthy and mentally normal.

2, autologous fat injection filling the law line for the first half of the month, no anticoagulant drugs and aspirin.

3, female patients as far as possible to avoid menstrual period of autologous fat injection filling law lines, bath before surgery, keep clean.

Treatment and process

1, fat aspiration: in the obese parts such as the waist and abdomen, thighs, buttocks, etc. using swollen anesthesia techniques, with a liposuction device to pump the subcutaneous fat required for transplantation.

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

3. Fat injection: The purified fat granules are injected into the nasolabial folds, and massaged and appropriately pressure-wrapped after operation.

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

treatment effect

Firming facial skin, lifting facial soft tissue or filling the nasolabial folds to remove or reduce nasolabial folds and improve facial aging.

complication

1, local skin unevenness: generally 3-6 months after surgery, the body itself can be adjusted, most can be restored to level, if there is still uneven, need to go to the hospital for correction.

2, lipoma formation: granule fat injected under the skin can accumulate, or stimulate the host cells to increase lipoma. After the formation, it is only removed to the hospital by means of excision.

3, fat liquefaction: excessive injection of fat tissue, or after the injection of fat tissue naturally aggregate, resulting in the injection of fat failed to survive, resulting in fat necrosis, liquefaction. When fat liquefaction occurs, it is necessary to go to the hospital to puncture the liquid or negative pressure drainage.

Rehabilitation and care

1. In the 24 hours after the hyaluronic acid eliminates the law, in order to fix the shape, avoid contact with the injected area.

2. Do not apply cold or hot compress to the area where the hyaluronic acid is removed.

3, hyaluronic acid to eliminate the law to avoid strenuous exercise within a short time.

Risk and prevention

1, infection: infection usually occurs 5-7 days after surgery, infection with local redness and heat pain, severe local skin flushing cyanosis or pinholes do not heal pus. When you have symptoms of infection, you should go to the hospital in time.

2, hematoma: liposuction and injection, may form a hematoma. Under normal circumstances, no serious hematoma will occur.

3, skin freckle: skin ecchymosis is caused by blood oozing. Skin ecchymosis generally does not require special treatment and can resolve within 2-3 weeks.
