Nanofat Grafting Survival Rate (feat. Upper and Lower Eyelid Fat)
Learn about nanofat grafting for hollow eyes. Discover the differences between microfat and nanofat, the procedure process, and how it improves survival rates.
Nanofat Grafting Survival Rate
Let’s take a closer look at the survival rate of nanofat grafting.
When there is hollowed-out skin above the eyelids or under the eyes, fat grafting is often performed to restore lost volume.
In such cases, you can choose between standard fat grafting, microfat grafting, or nanofat grafting.
- Standard Fat Grafting: Clusters of fat cells ranging from several hundred μm to several mm in size.
- Microfat Grafting: Fat particles approximately 400–600 μm in size.
- Nanofat Grafting: A liquid form of fat where cell membranes are broken down, primarily consisting of stem cells and growth factors; fat particles are microscopic.
These are the primary differences.
When injecting fat into the upper eyelids, standard fat can sometimes result in lumps or be felt under the skin. To minimize these issues, nanofat grafting is used.
Because nanofat is almost liquid in consistency, it is excellent for creating smooth, natural shapes.
Extraction is performed using specialized tools. This may involve mesh-type filters or commercial products like the Adinizer.
These types of devices are commonly utilized.
Post-operative appearance
The injection is performed in this manner.
Fat is typically extracted from the thighs or abdomen and then injected into the upper eyelid area.
The surgery time is usually within 20 to 30 minutes if only the fat grafting is being performed.
