I can feel teardrop implant move. Why is this?

Your breast implant is not attached in one place. It is placed in a pocket in which it will move as you move. There is no way to affix an implant to a spot on your chest wall. Textured implants tend to move less and the dimensions of the pocket can affect movement but the fact that the implant moves is irrelevant unless the appearance changes, as your surgeon told you.

Your implant isn't permanently attached to anything so there should be some movement when you move. It's part of what makes them look natural. However, keep an eye on it as too much movement can increase the chances that your implant may rotate. For now, though, nothing to worry about. Best, Dr. Nazarian

The bottom line:I agree that this should only be a thought/worry/concern IF the shape changes meaning the implant has shifted. Until that point, it's all worrying for nothing and time better spent other ways. Shaped implants have a rough surface so that your body will heal and adhere to them, keeping them locked in that position like a Velcro shell. Sometimes, the implant can pull free from this adherence and move more freely, potentially allowing to change positions or flip. This is possible in your situation, but it also could just be a difference in the way that one side feels or moves in contrast to the other. There's no great way to know for sure, and in the end, it's not worth worrying about because the implant may be "locked" or even "unlocked" and unlikely to change positions. All this is stress which may be for nothing. Try to put it out of your head, and if one day there is actually a change, simply visit your surgeon and get examined. Good luck!Dr. Subbio
