What is this Deformity when i lie down? Can this be fixed? (Photos)

Hello and thank you for posting. This is not bottoming out and it is not a deformity. It is just your implant. The breast falls back when you are laying down but the implants stay in place because they are being kept in place by the muscle. Making your breast tissue tighter will help avoid the tissue displacement, but this would entail a breast lift. Another option is loosening the pocket. This will make it so the implants have more room to move with your breast tissue but this would mean a pocket revision and a wide or big pocket may increase the risk of implant displacement or bottoming out.
These are your best options but if it doesn’t bother you too much it is ok to leave it as is. There’s really nothing wrong with the implant or the procedure. It is up to you.

Best of luck,

Thanks for your question. It is very difficult to tell based on your photographs but it looks like the edge of the implant is visible in this area when you are lying down. This may be because there is a problem with the underling implant (for example rotation), or the soft tissues overlying the implant are not appropriately tailored and are falling off the implant, leading to visibility, meaning that you may benefit from tightening of the skin envelope via an uplift. See a plastic surgeon on the specialist register with a practice centred around aesthetic breast surgery.

Hi from İstanbul.Many thanks for your question.It is not possible to understand and comment clearly from the pictures, but as far as I can see, there is a possibility that the implant has rotated, so I recommend that you consult your own doctor and have a physical examination. Your own doctor will make a more accurate comment because he knows the technique he used during the surgery.
