7 years post op, implant has significantly droped and changed in size - could this be implant rupture? (photo)

You have bottomed out with your lower implant. If the other implant is smaller than it used to be, you may have deflated. I would suggest contacting your plastic surgeon.

Your post is intriguing. Patient who experience rapid the deflation of one breast size after breast augmentation typically have a ruptured saline implants. When saline implants rupture, the body will absorb the saline breast typically shrinks fairly rapidly. When silicone implant rupture, there is usually no change seen at least initially. A ruptured silicone implant will maintain its volume. Ruptured silicone implants can create capsular contractions, making the breast hard and distorting the contour.
Your right breast implant has bottomed out, and this should be addressed as well. I suggest finding a plastic surgeon who has extensive breast implant experience and can address both issues with revision surgery.
The rapid change in size doesn’t make sense if you have silicone implants.
Patience to get implant augmentation are given an ID card with her implant information. Perhaps you have that card available? If not, I suggest getting a complete set a before and after pictures and your operative report from your previous provider if you decide to go to another surgeon.
If your surgeon is still available, then follow up with him or her. Managing a bottomed out implant like you have on the right can be a bit more complex and getting this to look correct it’s a bit of a finesse procedure.
Simply, exchanging implants is not particularly difficult, but dealing with a bottomed out implant is not necessarily straightforward.
