The incision for the implant to be inserted can be made in four different places :
There is a scar on the breast, but it is barely visible.I generally place my incisions 4-5 cm long, in the inframammary fold. It is the easiest way and one that gives good access to stop bleeders. It is also the only way in case of anatomical implants.
The peri-areolar scar is on the edge of the areola. One needs to have reasonably large areolas. I don't use it often,because it is an access through the breast, which leaves scar tissue which is difficult to discern from beginning cancer on an X-ray. Also the nipple sensation can be diminished.
The transaxillary approach has a scar behind the fold in the armpit. It has the advantage of being less visible. But the approach is blind, meaning that there is no control of bleeding vessels and a higher incidence of capsular fibrosis.
