Why does my left breast implant shift and crinkle when i flex my pectoral muscle? (photo)

Based on the photos provided, you appear to be very thin with every little fat or breast tissue coverage of the breast implants. this increases the likelihood of visible or palpable wrinkling of the implants. Textured implants also have a thicker shell which increases the probability of wrinkling. A submuscular plane of breast augmentation will minimize this type of wrinkling. Generally implants placed above the muscle ie. prepectoral will not animate or wrinkle with muscle contraction. I therefore can’t explain the wrinkling with contraction unless, perhaps, the surgeon placed the implants subfascial?

Your implants are too large for your frame and tissue. You need to go smaller and consider some mesh for better coverage.

Visible wrinkling of implants is not uncommon in the absence of adequate tissue coverage. Your photos suggest that you have very little native breast tissue and no significant fat. When coverage is largely skin as in your case, the wrinkling of implants will often be visible. A diagnosis of ruptures requires radiologic imaging, most commonly by a high-resolution ultrasound. Regarding your other questions and concerns, a physical examination would be required. A consultation with a board-certified plastic surgeon would be appropriate. He or she can arrange for an ultrasound, discuss options to reduce the rippling, and diagnose and treat your other concerns.
