What is the Difference Between Fat Being Above the Muscle or Under the Muscle on Stomach?

will it effect the outcome of a full tummy tuck w/lipo flanks?

Fat inside the abdomen, surrounding your internal organs plays a role in the width of your abdomenal girth. However, I have never heard of a plastic surgeon who will remove any of this fat.

The fat removed during liposuction or a tummy tuck is fat outside the muscles that protect your internal organs.

Therefore if you have a lot of fat inside the muscles, plastic surgery will not address this concern.

Belly fat on top of vs. below muscle.

+1

When talking about the abdomen...  The fat anterior to, (on top of), the muscle is available to the surgeon to be suctioned out, (liposuction), or cut away, (tummy tuck).  Fat that is posterior to, (under), the muscle can't be addressed by surgery.  This is why in some patients you can't pinch fat, but they have a belly that protrudes.  Diet and exercise is the way to get rid of the fat posterior to the muscle.

Only subcutaneous fat is accessible to liposuction and tummy tuck

+1

Only fat that is above the muscle (between the skin and the muscle wall) is accessible to treatment with liposuction and tummy tuck.  This is called the subcutaneous fat.  The fat on the inside of the abdomen, wrapped around your organs, is called visceral fat and this fat only goes away with weight loss.  This is why people with "beer bellies" may not be good candidates for surgery (but may be if they lose weight).

You appear to have a combination of excess subcutaneous fat and an abdominal deformity.  You would be best treated with a combination of abdominoplasty and liposuction.  The liposuction will reduce your hips and flatter your figure by promoting the curves of your buttocks.  You might consider simultaneous fat injection of the buttocks.

I have attached some examples from my website .

Location Of Abdominal Fat

+1

There are two areas in which excess fat is stored in the abdominal area.  Some fat is, as you mentioned, above the abdominal muscles.  This fat can be addressed with both abdominoplasty and with liposuction.  The other fat is not only "located below the muscle", it is located within the abdominal cavity (primarily in the omentum) and as noted by others cannot be addressed by any plastic surgical procedure.  The only mechanism for reducing the intra-abdominal fat is with generalized weight loss.  The intra-abdominal fat is more common in men, but can be seen in women to varying degrees as well.

Abdominal fat is not all the same.

+1

There are two main areas for fat deposits in the abdomen: The subcutaneous fat located directly under the skin, and the visceral fat located within the abdomen (under the muscle) surrounding the intestines and organs. In body contouring procedures, the subcutaneous fat is the fat that is liposuctioned, directly removed, and sculpted. The visceral fat is never removed or manipulated with body contouring. There are physiologic differences to these fatty deposits as well. The visceral fat is considered a "metabolically active" fat. This means that it changes in volume much quicker than subcutaneous fat (ie it can be readily removed when the body needs energy). The visceral fat is also more closely linked with cardiovascular disease (strokes, plaques, heart attacks) than subcutaneous fat.

Visceral fat makes up the majority of "beer bellies" that we see in men. The way to reduce visceral fat is through diet and exercise, not surgery (except for gastric bypass). High amounts of visceral fat will lead to issues with rectus muscle separation, abdominal wall hernias, etc. For patients undergoing a tummy tuck, the Plastic Surgeon will often attempt to quantify how much visceral fat is present versus how much subcutaneous fat is present. If a lot of visceral fat exists, the results from a tummy tuck may still have quite a it of abdominal bulging. This is distressing to patients if they are not educated about the limitations of abdominal contouring.

Abdominal Fat Location and Tummy Tuck Results

+1

For purposes of discussion, the abdominal (tummy) region may be thought of as being comprised of five physically distinct layers. From the most superficial layer to the deepest layer, they are: skin, fat, muscle, the lining of the abdominal cavity, and, lastly,  the abdominal cavity itself.

Anatomically, the fat in the abdominal region is located in two distinct areas and is referred to as being either extra-abdominal or being intra-abdominal.

Extra-abdominal fat is the fat that is located just below the tummy skin and it sits on top of the abdominal muscles; this is the fat that is physically removed during a tummy tuck procedure. Fat found in the hip/waist/flank, and back areas that is located at this same level (below the surface skin but above the muscle) is removed during liposuction procedures.

Intra-abdominal fat is the fat that is found inside the abdominal cavity (remember this cavity anatomically exists far below and is deeper to the tummy muscles, being physically separated from them by the lining of the abdominal cavity), along with the intra-abdominal organs such as the gall bladder, uterus, intestines, spleen, and kidneys, etc. This fat is intimately  associated with the arteries, veins, and lymphatic channels associated with these intra-abdominal structures and the critical maintenance of their functions and, therefore, is never involved in the tummy tuck procedure. Furthermore, this intra-abdominal fat responds favorably only to the increased caloric expenditure and decreased caloric intake associated with weight loss. 

In my opinion, a critical component to the result of a tummy tuck involves the  tightening or repositioning of the tummy muscles back to their most optimal anatomic location with the use of sutures.  However, the presence of excessive intra-abdominal fat may place too much pressure on the back side of the abdominal musculature and may physically impede the adequacy of any attempted muscle tightening/repositioning; the end result could be a suboptimal visual appearance of abdomen (persistent convex or protuberant shape).  In combination with the removal of pre-existing flank fat by liposuction, this undesirable effect may be even more dramatic.  

Additionally, muscle tightening in the presence of too much intra-abdominal fat can even result in difficulty with breathing after surgery as the tightened muscles may put pressure on the intra-abdominal fat itself (same amount of intra-abdominal fat now in a smaller space brought about by tightened tummy muscles) which then interferes with the dynamics of breathing.

Routinely, a well-trained and experienced tummy tuck surgeon will determine the physical contribution of both the extra-abdominal and intra-abdominal fat layers to the visual appearance of the tummy area before surgery such that he/she will, ultimately, be able to deduce the likelihood that the presence of excessive intra-abdominal fat will limit the results following surgery.

Fat Content

+1

People come in all shapes and forms and how they are genetically determined to carry their body fat varies tremendously. Some people store their fat on their hips, some on their legs, and still others within and around their abdominal organs like their intestines, liver and pancreas. If a person caries a large amount of fat around their organs, it can push out on the overlying muscle wall and cause it to bulge.

Unfortunately, it is not safe to remove fat around your organs. This would be outside the scope of any plastic surgical procedure. The muscle wall can be tightened pushing in on your organs: this would be the equivalent of and internal corset. However there will be a limit as to how much this can be tightened. 

I hope this is helpful for understanding the limits of your upcoming procedure and I wish you all the best.

Fat above and below the muscle

+1
I agree that the fat below the muscle cannot be addressed with any plastic surgery procedure. A tummy tuck will address extra skin and fat above the muscle, but the final contour of your waist will be greatly limited by the fat below the muscle. For the best result, you need to loose the extra weight first.

Fat above or below Muscle in Tummy Tuck

+1

The abdominal wall is very uniform. You have skin, Fat then Muscle. Muscle is surrounded by Fascia which houses the Muscle (Rectus Ms.) . Below this layer is the abdominal cavity which houses your intestines and the omentum ( Fatty apron that lives in the cavity). 

So, the only fat of concern with a tummy tuck  and lipo is above the muscle,  none below the muscle. The omentum is in the abdominal cavity and can lead to increase in abdominal girth. It can not be affected by any plastic surgery procedure. This is very common with men more then with women.
