I had revision surgery to fix bottomed out implants. Have they bottomed out again? How can this be fixed? (Photos)

Hello! Thank you for your question.
Everyone has a unique footprint of their breasts on their torso. Yours do sit on the lower side which is something you cannot change. It's part of your anatomy.
Your implants do seem to be settling. This could be related to your skin being able to support the implant, whether it be due to your intrinsic skin quality, possibly also the weight of the implant. Options would be to improve support with a mesh, like Galaflex, and/or reducing implant size.
Hope this is helpful for you. I would recommend you seek guidance from a board certified plastic surgeon near you. You can find one at plasticsurgery.org.

yes, it appears you have asymmetric implant positioning with the left sitting considerably lower than the right side. Implant malposition can occur for a variety of reasons including implant selection, tissue quality, and pocket position. For patients that have had recurrent issues with implant malposition, I often will recommend incorporating a combination of capsule tightening (Capsulorrhaphy) and tissue support with some type of mesh product depending on the specific surgical needs. Ultimately, what needs to be done surgically depends on your anatomy and the problem. For some patients, this means requiring reinforcement of the breast fold while others have excess stretch of the lower pole of the breast and need offloading with a internal bra support. Consult a well-qualified plastic surgeon who can give you recommendations based on an in-person exam.
