There are many approaches to incisions in breast augmentation, and this can be confusing for patients. In general, most surgeons favor one approach. While none of the incisional approaches are bad, some have disadvantages. I favor the inframammary incision. This places the incision in the crease of the breast. In my opinion, this incision enables the best positioning of the implant, provides a well hidden scar, and yields the most natural result. The inframmary incision is particularly good when placing silicone gel filled implants as these require a slightly larger incision than saline filled implants.
Placing the implant through the armpit (transaxillary approach) can lead to an unnatural or high-riding appearence. Placement of the incision around the nipple (periareolar approach) can lead to an unfavorable scar or distortion of the nipple.

Below is some information from Mentor on incisional approaches which is helpful in understanding the different surgical incisions which can be utilized.
