My breasts fall into my armpit 8 month after breast augmentation! What should I do? (Photos)

I am sorry you are having this problem. It appears that your implants have become laterally displaced and you may need a revision, which involves closing off the pocket laterally, preventing the implant from falling off when you lie down.  It is a fairly straight forward procedure. Talk to your surgeon, as I am sure he or she will be happy to help. Good luck!

I am sorry to hear about the problem you are experiencing. You demonstrate your concerns nicely. Although some “falling to these sides” of breast implants is quite normal when you lie down, if this occurs “excessively”, it may be a concern to patients.  This phenomenon is called lateral displacement of the breast implant;  it may be of concern from the visual and the discomfort standpoints. Surgical correction is an option.
Generally, the lateral breast implant displacement can be corrected using an internal suture technique, decreasing the size of the pockets and moving the implants toward the midline.    In my practice, I use  a 2 layered suture technique (capsulorraphy) to close off the space laterally (towards the axilla). The use of acellular dermal matrix is an option ( although not usually necessary)  especially if significant implant rippling/palpability is present.
I hope this (and the attached link) helps. 

Thank you for your question and photographs.  Sorry that you are not happy with your surgical result.  Best to consult with your plastic surgeon regarding options for correction.  Scars that are red and itchy are quite normal and indicate healing.  Best of luck.
