Your implants are positioned high and although they will drop over the next few months, it is not likely they will ever adequately fill the bottom part of your breast. The lower part of your breast is constricted (which is more marked on the left side); a problem that is not uncommon in people coming for breast augmentation and needs to be surgically released. I suspect you started with a difficult problem and had preexisting breast asymmetry, and it is not possible to make a full assessment without your pre-operative photographs. Asymmetry is difficult to correct, as placing different sized implants means they have different widths and can magnify the asymmetry. In your case, it appears much of the asymmetry is caused by the greater constriction on the left side (in the bottom part of your breast) compared to the right which needed to be released. This would make a larger space for the implant in the lower part of the breast where you are lacking volume. The "side-boob" is due to an implant which is too wide for your existing chest wall. The most important determinant of which implant is best for you is its base width, which must conform to your chest wall width within certain limits. Once this measurement has been assessed, the volume is selected based on implants that have the correct width for your chest wall. Let your results settle over the next few weeks-months, however, it is important you address your concerns early with your plastic surgeon if you feel things are not improving. Most surgeons would offer a revision if you are unhappy after the 6 month mark.
