Is this a lateral breast implant displacement? (photos)

You need an examination to see what is happening and if it this normal. I would suggest going back to your surgeon and discussing your concerns.

Thank you for your question. Breast augmentation surgery with smooth surface implant may cause the implant pocket to get gradually widened after the surgery. To prevent the pocket widening, it is necessary to wear a proper supporting bra to control the implant position for several months after the surgery. If such effort doesn’t solve the problem, revision surgery to close the excess space should be considered. I can see that you are very concerned about your surgery outcome, but I can say that properly conducted revision surgery with experienced doctor will bring you good results.

HI there,
I came by your question and I'll do my best to answer it. Based on the pictures, it almost looks like the left lower pole of your breast is still tight and the implant hasn't "settled". If the implant feels like it's going into your armpit as oppose to the bottom of your breast, sometimes it could be from tightness of the tissue that is still present because of inadequate release or capsular contracture on one side. However, looking from the frontal view, they look pretty symmetric and evenly space. Implants can take up to year to stretch out the skin below so that can still be possible. As long as the pain continue to improve, I wouldn't worry about it. You show take more prospective pictures every 2 weeks to see how the breast shape is changing for your own records so you have something to compare to. Hope that answer your question.
