Does Breast Implant Profile Matter in Preventing Bottom Out?

Implant size, not implant style, may have more to do with bottoming out in your case. Once the inframammary fold is repaired or reset, a smaller (and therefore lighter) implant will help prevent this problem from recurring in the future. The difference between high profile and moderate plus profile is a matter of millimeters. The most important treatment here is the surgical repair of the fold, not so much the implant style choice.

Larger implants are heavier and therefore more likely to migrate downward causing bottoming out. Textured implants adhere more and are less likely to do so. 

"Bottoming out" is a term that originally came from breast reduction surgery.  Post-op, we would notice that, over a year or more, the lower half of the breast stretched out, while the nipple position maintained itself pretty well.

While this can happen after augmentation, due to a heavy implant, or stretchy skin, some surgeons confuse this with descent of the implant pocket or  "pocket expansion", which is a different situation.  Here, the implant drops lower, acting like a wedge between the skin and the chest wall, opening up the tissues.  Essentially, the implant is sliding down the rib cage, and the level of the inframammary fold descends, and the nipple starts to point upward.

Based on your information, I can't tell which of these problems you have:  inferior pocket expansion or true bottoming out.

The treatments are different for the two problems - which is why it's important to make an accurate diagnosis.

But no, implant profile by itself has not been linked to a higher rate of bottoming out.
