facial fat grafting

The most common issues are unevenness and lumps. Most of these stem from the method of insertion.

Causes ① Concentration into a single layer ② Fat cell damage ③ Thick cannula on thin skin

If a large amount accumulates in one spot, blood vessels cannot reach the center, causing some of it to necrose and remain as a lump. The skin on the face is thinner than on the chest, so even the same amount is more easily palpable.

Limit Whether the existing lump is fat necrosis or a simple clump First, distinguish using ultrasound.You must do it. The treatment is completely different.

The forehead has a thin layer of skin covering the bone, so if it clumps together in one spot, it can be felt immediately.

So, the forehead is more than the amount put in Method of spreadingThis is important. Divide the thin stems and lay them out from multiple directions, and do not fill the desired volume all at once.

Limit If you try to fill it all in at once, the shape may appear immediately, but absorption and clumping will occur simultaneously. It is better to do it in stages for more stable results.

The fat that has taken root remains as your own tissue. You need to separate the amount absorbed from the amount that remains.

Initially, some fat is lost along with swelling, and the engrafted fat is retained thereafter. Therefore, rather than focusing on 'how much percentage remains' How much grafting is achieved?is the key.

Limit The figures above are derived from breast research and do not apply directly to the face. It varies depending on the site, injection volume, and individual conditions. You should also consider that this is our own in-house research.

This is based on our own research standards. It is not an independent third-party verified study, and therefore cannot be directly compared with studies involving different subjects or measurement methods.

We check after the first treatment has settled. Swelling is usually less after the second treatment.

If done too early, absorption is still in progress, making it impossible to determine what remains, and adding more in that state results in overcorrection. For the second session, a smaller amount is injected and the dissection area is narrower, resulting in less swelling.

Limit It depends on the area. It is appropriate to determine the timing after observing the initial progress.

The purposes are different. It depends on whether it is reversible or long-lasting.

Fillers — Immediate shape, reversible, fixed duration / Fat grafting — Patient's own tissue once engrafted, requires time

If you already have fillers, you need to remove those first. Space for fat injection and blood flow conditions are secured. Placing fat directly on top of filler is disadvantageous for engraftment.

Limit It is impossible to generalize which is 'better.' The answer varies depending on the depth of the depression, skin thickness, and past treatment history.

Skin boosters address skin texture, while fat grafting fills in lost volume. Different causes lead to different solutions.

The reason your nasolabial folds appear deep depends on whether it is due to sunken cheeks or sagging skin. If the loss is caused by a loss of cheek volume, a booster will not solve the problem.

Limit Conversely, if there is volume but the texture is coarse, fat grafting will result in overcorrection. We first determine this using 3D measurement.

In many cases, reinforcement is possible. However, the area under the eyes is the part that requires the most caution.

Relocation Moving existing fatIf there is insufficient fat to transfer or the furrow is deep, fat remains. In this case, it is reinforced with micro fat grafting.

Limit The skin under the eyes is the thinnest, so even a slight excess can cause it to show through or clump. A very small amount must be injected in divided layers within the shallow areas, and it is safer to wait until the tissue has stabilized after repositioning before viewing.

While it is often possible, putting the same amount in the same place does not bring it back.

The space created by the removal surgery differs from the original fat layer. We design the plan by analyzing the depth of the sinkhole and the degree of sagging.

Limit The approach varies depending on whether the issue is solely about volume or if sagging skin is also present. In some cases, fat grafting alone may not be sufficient.

Maintaining weight, quitting smoking, and avoiding pressure on the surgical site — these are the three things you can do.

Rapid weight loss also reduces engrafted fat. Smoking interferes with the process of blood vessel growth.

Limit The rest are surgical conditions — how to extract, how to purify, and how much to distribute to which layer. Graft success is determined not after insertion, but from the moment of removal.

This method uses the same autologous fat but includes the stromal vascular fraction (SVF) separated from the fat.

Separation Method — SVF separation by collagenase enzyme treatment + centrifugation · 3D volume measurement

The theoretical basis is that SVF contains cells involved in creating new blood vessels, which helps speed up blood flow to the transplanted fat. We have been performing surgeries using this method since 2007.

Limit SVF isolation methods and cell counts vary by study and hospital. It is difficult to directly compare the figures. It is not necessary for everyone, and the decision depends on the body part and condition.

This is based on our own research standards. It is not an independent third-party verified study, and therefore cannot be directly compared with studies involving different subjects or measurement methods.
