Tummy Lipo Insertion Points?

The belly button is a common area used to access the abdomen, and more incisions can be used but may not be needed.  If you have weak muscles causing your abdomen to protrude, or a fair amount of intrabdominal fat, even a whole liter of fatty tissue removed from the abdomen may not look as dramatic as it does in other areas like you hips or back where the fat overlies only muscle and bone.

Typically a third to a quarter of the fullness making an abdomen protrude is due to the fat that the liposuction canula can reach.  The other three quarters to two thirds lies inside the abdomen depending on your genetics and weight. 

It would be helpful to know how far out from surgery you are. If it is a month, it would not be surprising to see little difference. If it is six months, any swelling should have resolved, and this would probably be your final result. 

There are numerous techniques for liposuction, and much depends upon the location and quantity of fat. The navel is a common port site because the scar is hidden. I will usually add two groin incisions to do the entire abdomen, but if a small localized amount of fat is present, sometimes the navel alone is enough.  There are as many ways to do this as there are patients.

All the best.
