Hi Rachel
There are three different placement types although I believe mya only offer over the muscle or partically under the muscle … Think only in certain circumstances do they put the implant fully under the muscle.
There are pros and cons to either placement for example overs tend to soften quicker and you usually have a quicker healing time as the muscle hasn’t been lifted. Overs also tend to be better if you do a lot of exercises that use your chest muscles as they are less likley to distort when the muscle is flexed. However overs have a slightly higher risk of capsular contracter and I think may have a slightly higher chance of bottoming out.
Unders/partials take longer to heal but give the implants a little more support as they are held by the muscle and not just the skin. They are also better if you have little or no breast tissue as they hide the implant edge giving a more natural look. The thing however that can occur with this type of placement is what’s called the double bubble, which is if your breasts were to sag but the implant stays in place under the muscle causing ridge or slight double boob effect.
Overal I think the best way to decide is research view pictures of people with different placement types … Bare in mind your shape and stats etc this will help you decide what sort of look you would like.
The big thing is by all means get ideas and research but don’t get your self to set on a placement until you’ve met your surgeon as they have seen many women and can help recommend the best placement for your body and for the look you want to achieve .
