I’m not sure there’s an actual name for your breast concern, but I will attempt to give you an explanation of why this may be occurring. First of all in order for us to make quality assessment we need quality information and that generally means always including proper before and after pictures. If you don’t have before, and after pictures, then ask your surgeon to forward the pictures they took. we usually make assessments based on patients in an upright standing position. My best guess on why your breast look the way they do when you lay on your back is the following. I’m guessing that your breast were relatively small before the procedure and that you have fairly large implants relative to your breast size before surgery. When surgeons use breast implants that are wider than the natural breast diameter the IMF or infra mammary fold needs to be opened up in order for the implant not to sit too high. When you land your back, the implant is probably moving up slightly, and this causes the change in breast shape. If you push the implant down with your hand by putting gentle pressure on the upper part of your breast, I’m guessing that your breast shape looks normal when you’re laying on your back. My best guess is that this issue would be less likely had smaller implants than used. I don’t think it is related to how the procedure was done other than the IMF was probably opened to accommodate the size implant used. Anytime, excessively large implants are used the chance of undesirable side effects, complications and need for revision surgery will always go up. I have no idea what size implants you have and I don’t know what your breast look like before. I suggest you follow up with your provider. I don’t think you should have any intervention for this. I think it’s simply part of what happens when the procedure is done in certain ways especially using larger implants. Best, Mats Hagstrom MD.
