For breast reconstruction, we usually prefer the muscles of the rectus abdominis. Unless you are very strong and your latissimus dorsi muscles are well developed, you can use them. It also depends on the size of your opposite breast. If your opposite breast is small, you may be able to use the latissimus dorsi muscles. If the opposite breast is larger, then your latissimus dorsi muscles are not enough. Another thing is that there are some defects after the latissimus dorsi muscles are done. For example, after you remove the latissimus dorsi muscle, the side taken out is concave and deficient, so the shape of your back is not as perfect. However, most women have a lot of rectus abdominis muscle, which can be removed to give you a more perfect body shape.
