What is the most common amount of distance between the pectoralis major muscles?

Question

Hi, I'm just curious what is a common gap/ distance for the pectoralis major muscle? Like how much space is it between the muscles on the sternum? I understand everyone is different but what is most common from your experience? And how close would you say you can go when doing dual plane type 2 without causing symmastia?

Aaron Gilson, DO · Answer

The gap between the pectoralis major muscles, which is typically measured at the sternum, commonly varies from 1 to 3 centimeters in most individuals. This anatomical feature is quite normal and varies widely among different people due to genetic differences in muscle structure and chest shape.

When performing breast augmentation using the dual plane type 2 technique, it's crucial to avoid bringing the implants too close together to prevent symmastia, often referred to as "uniboob," where the tissues between the breasts merge. The goal is to enhance the chest while maintaining a natural-looking separation between the implants. Proper assessment and technique by a skilled surgeon are essential to achieve this balance and avoid complications.

It does not matter to know how common the gap is. It matters to know it for each patient. That is a set fact that cannot be changed unless risking symmastia. Dual plane should not cause symmastia.

I recommend an in person consultation with a plastic surgeon to discuss your goals and be measured. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size and style breast implants, if interested. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what size and style breast implant is right for them. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author.

There is a very wide variety of distance between the two breasts based on the location of the breast bases and the size of the chest. Some women naturally are several centimeters apart.  wider based implants do help minimize the space, but the bases cannot be moved. Please do not choose implants that are too large for your frame and tissue.
