Inframammary Fold: The most common place for your incision is in the fold underneath your breast. This is called an inframammary incision. There are several reasons to choose this incision.
First of all, it is a well-hidden area. Generally, you will only see it if you lift up your breast or you are laying down topless. It can be hidden under almost any bikini. It gives the surgeon a good point of view to make the best shape and symmetry. It also has the lowest risk of problems like capsular contracture in the long term.
Periareolar incision: Another option is an incision around the bottom of your areola where it meets the normal skin. This is called a periareolar incision. This can be a well-camouflaged area for the incision.
However, if the scar does not heal well, it can be a very obvious scar. Also, there is a higher risk of capsular contracture and possibly infection since the implant has to go through all the breast tissue, instead of underneath it like in the inframammary incision
Axillary incision: Implants can be inserted through an incision in your armpit. The advantage is a well-hidden scar. The downside is that the surgeon does not have as good of a point of view to place the implant correctly, and again, there is a higher risk of capsular contracture than there is with an inframammary incision.
