How to increase the survival rate of fat grafting

Fat filling is a relatively common plastic surgery method, especially autologous fat, which has a relatively high survival rate because it uses one's own fat and will not be rejected. Of course, in order to improve the survival rate, it has an important relationship with the doctor's transplantation technology, physical constitution, fat conditions, nursing ability, post-maintenance, etc. In addition, it also has an important relationship with the part of the plastic surgery.

No.1 Yamagen

Most people physiologically do not have fat at the bridge of their nose, so the final result of fat filling this area may be that all of it is absorbed. Therefore, no matter in terms of filling shape or survival rate, the bridge of the nose cannot be permanently raised by fat filling. If the bridge of the nose is too low and affects the effect of the entire face filling, I will fill fat in this area during the operation, but I also often tell the patient to consider further rhinoplasty or hyaluronic acid filling in the future, otherwise an ugly nose will seriously affect the final facial shape.

No.2 Nasolabial folds

It is common for Asians to have a sunken nose base, which is more likely to cause visual enhancement after filling the apple cheeks. Therefore, apple cheek filling is often accompanied by nose base filling. However, since the nasolabial fold is the insertion point of many of our facial expression muscles and motor muscles, the area where muscle movement is active will affect the early angiogenesis of fat. Therefore, laughing less, talking less, and chewing less are the key to maintaining the survival of fat in this area. However, based on clinical experience, the nasolabial fold is still a relatively easily absorbed area, and is more suitable for treatment with hyaluronic acid filling or face lifting after surgery.

No.3 Chin

The fat of the chin is filled in the subcutaneous tissue, mentalis muscle and periosteum. People with poor congenital conditions have less jaw tissue than normal people. In addition, the chin cannot be avoided from moving when we eat, drink and talk. Therefore, the survival rate of fat in this position is also very low. If you want to make minor adjustments to your morphology, you can try chin fat filling, but for those with severe chin retraction, the better option is still a prosthesis.

No.4 Temple

The anatomy of the temple is complex, with intricate blood vessels and nerves. If the operation is improper, there is a possibility of distal ocular vascular embolism, so be extremely careful. In view of such concerns, on the basis of reducing the difficulty of surgery and improving the safety of surgery, the filling levels for patients with sunken temples are relatively conservative, especially avoiding the superficial temporal fascia layer, and only filling is performed in the subcutaneous or middle temporal fascia layer. Therefore, the fat survival rate is also relatively limited, and multiple fillings are required to achieve satisfactory results.

No. 5 Both sides of the forehead

Some people have the habit of raising their eyebrows unconsciously. Similarly, places with active exercise will affect the regeneration of fat blood vessels and cause the absorption of transplanted fat. After many people have forehead fillers, the fat from the center of the eyebrows to the top of the head is well preserved, but more fat is absorbed on the sides of the forehead, mostly due to the patient's habitual eyebrow raising. In order to increase the survival rate of fat, you can consider using botulinum toxin to control muscle movement, which can also achieve the effect of removing forehead wrinkles at the same time, which is like killing two birds with one stone.

Other parts such as the front of the forehead, brow arches, apple muscles, cheeks, tear troughs, and lips (rich in blood supply) are all areas where fat is relatively easy to preserve. The key to improving the survival rate of fat is to improve the conditions of the recipient area. It is crucial to ensure the stability of early vascular remodeling of transplanted fat. All you can do is not to rub or touch it, laugh less, chew less, reduce facial expressions and talking frequency as much as possible, do not disturb the growth of fat, and spend the month after the operation peacefully.
