Does Fat Injected Deep into the Muscle Last Longer?

When performing a buttock augmentation with fat (Brazilian buttock lift) the majority of the fat is injected deep into the gluteal muscles.  The reason for this is to increase the survival of the fat cells as the blood supply within the muscle is far greater than the blood supply to the skin.  Superficial injections tend not to survive very long and contribute to a lumpy/bumpy appearance and fat atrophy (shrinkage).

Please consult with a board certified plastic surgeon who is experienced with these techniques.

I prefer to inject the fat into tissue with excellent blood flow.  Muscle is a great location in which to inject the fat. Some of the fat is injected into the fatty layer on top of the muscle also.  Another ciritical aspect is to deposit the fat in layers to allow the fat to be nourished by the surrounding tissue.  This has been shown to improve survival of the fat.

Most practitioners prefer to inject the fat into vascularized tissue with muscle being one of the optimal targets. Another ciritical aspect is to deposit the fat in thin threads to allow the fat to be nourished by the surrounding tissue. This is similar to the way seeds are sown in soil.

Most likely yes because of the increased vascularity. I usually inject fat under the muscle, in the muscle and over the muscle for various reasons. This has to be done with care in a special technique as the larger vessels are found under the muscle.

Generally when fat is injected deep into the muscle it does last longer. When a Brazilian butt lift is done, some if the fat is injected deep into the muscle tissue but it is also placed into several different layers, deep and superficial. You do get more take in the deeper areas but to get the best results you do need to disperse fat in all areas. 

A Brazilian butt lift is a safe and effective procedure that can improve the contour of your butt and beautifully increase its size. This procedure consists of aggressive liposuction of the abdomen, hips, waist, flanks, thighs, and lower back. This collected fat is then processed and strategically grafted to the gluteal region. . For a successful result, the technique that is used is crucially important. Fat that is injected into the butt must recruit blood vessels for nutrition and to remain viable. In our practice, we inject the fat a drop of the time through many different layers of the butt. This allows the surrounding tissue to encompass the fat droplets and allows blood vessels to grow into the fat so that it remains viable. Keep in mind that when fat is transferred from one part of the body to another a certain amount of this fat will melt away. By only using the highest quality fat cells and distributing them throughout the butt in a way that the surrounding fat can incorporate these new droplets, we can minimize the amount of fat that melts away to provide the patient with a full and permanent result.

I inject 80% of the harvested fat in the muscle, and 20% in the skin/fatty layer.  The muscle has a robust blood supply and should make it easier for the fat to survive.  More importantly, the buttock muscle has fascial covering, like saran wrap, so when you inject  the fat it pushes against the muscle covering which gives a smooth result and avoids  "lumpy butt" which is quite ugly indeed.However, there have been reports of the fat being injected into blood vessels.  It is critical that the injector uses a gentle injection technique with small amounts of at in each location to avoid this issue
