Hi, high profile is a squashed version of the volume in the implants so it sits higher and more rounded, a moderate profile is a flatter version of the implant so it’s sits wider and less prominent if that makes sense. You may need a moderate if your chest wall as wider so as not to give a large gap in the middle. Or a moderate plus which is in the middle of both. There’s lots of images on google to have a look at. I’m 4days post op with 400cc moderate plus under the muscle ????.
