Do the Sientra textured gummy bear shaped implants will "giggle" like real breasts when walking, running, etc.

Thank you for your question about Sientra Breast Implants.No, in general textured anatomically shaped gummy bear breast implants do not typically "giggle" or undulate with movement.  They are more form stable and feel firmer that regular silicone gel breast implants.To be sure, see two or more experienced, board-certified Plastic Surgeons in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have surgery.I hope this helps.

For thin patients it is usually best to have the implants under the muscle for a more natural look. The cohesive gel shaped implants are firm and so they will not feel as squishy as natural breasts.

When replacing old implants that were likely smooth silicone gel or saline, you hopefully will find that Sientra cohesive gels are superior in comfort and shape. If your original implants are below the muscle, then I would place the new ones there as well.  It is a better pace for implants- having a muscle layer between the implant and your thin skin and breast tissues. It is better for mammograms and ultrasounds, and likely decreased chance of contracture and ripplesIn my practice, I have found that using a textured gel Sientra Implant provides and outstanding result in terms of comfort and shape. For a really thin patient without much droop, I like the anatomic shaped implants with the classic  base or round base-- they look amazing and are really natural in appearance. The do not ripple visibly.With motion and exercise, they stay put rather  than shift  much.  They feel really natural and soft, though do not "bounce and Jiggle".  That usually happens more in larger or  looser skinned patients  with a smooth implant that has room to move.  The textured gels will not move much. If your surgeon uses a smooth implant , then you may have more movement, which really does not change things much.  I use all three major brands of implants, and have found Sientra to be outstanding and are now my preferred implant. Best of luck in healing and a great outcome. I hope this information helps.

are firmer than standard round smooth implants... but they ripple less and are designed so they aren't supposed to have the mobility of a smooth round implant.  But when they do move, it could lead to malposition and more surgery.  If you like the movement of your current implants, it makes more sense to just have it replaced with smooth round gel implants.  What are the reasons for changing to a shaped gel implant?  And if you do go above the muscle, is your muscle going to be 'repaired'?  Lots of questions and you should make the best decision for yourself when you get all the answers.
