How do I prepare for a fat injection?
Fat injection is a more extensive procedure than the use of other cosmetic injectable fillers because liposuction techniques are involved. These techniques are used to extract the fat prior to injection.
While fat injection is a non-surgical procedure that is usually completed with local anesthesia, it may require local anesthesia with sedation if larger amounts of fat are being collected through liposuction methods.
Preparing for your fat injection may include:
- Lab testing or a medical evaluation
- Taking certain medications or adjusting your current medications
- Stopping smoking well in advance of surgery
- Avoiding aspirin, anti-inflammatory drugs and herbal supplements due to increased risk of bleeding.
How is fat injection performed?
Fat injection procedures are generally performed on an outpatient basis using local anesthesia. The procedure usually takes 30 minutes to an hour, or more, depending on the patient, the volume to be injected, and additional procedures that are being completed at the same time.
The fat is withdrawn from certain areas of the body (typically the abdomen or hips), either by using a needle or through techniques similar to those used during liposuction using a special suction cannula). Once enough fat is taken from the donor area, it is then purified through the use of a centrifuge, which spins the fat and removes impurities.
The fat is then injected into areas needing augmentation through an injection needle that is usually passed in and out of the specific areas multiple times. This creates a ‘grid’ of threads of fat graft.
