True cohesive round implants, meaning form stable round implants, have very little clinical use, and are not available in the United States. If you look at an implant lying on its side on a table, it looks much like an M&M. But when it is held upright, the upper pole gradually collapses. It is that upper collapse that allows those implants to look natural (though it is doing so at the risk of folds on the implant shell.) A true cohesive round does not do that. By maintaining that M&M shape when vertical, it creates a dome-like, relatively top-protruding shape.
However, cohesivity is not a black and white issue; there is an endless continuum in cohesive gel from very liquidy to very solid. On Silimed's cohesive clinical trial, there are 4 different round gel options. These are more cohesive than implants made in the past, and can be considered cohesive, but they are not as cohesive as their anatomically shaped cohesive gel implants or the anatomic cohesive implants by Mentor or Inamed. They fold less than gel implants of the past, but they are not quite form stable, in terms of their ability to resist folds or predictably maintain a shape.
