Were my breast implants malposition? Are they bottoming out on one side?

Thank you for your question.  It seems (from the pics) that there are a few things going on.  1- Yes, I think there is an element of "bottoming out"2- I think for you to get the best result, you will need a lift which also makes the areola size smaller and the breast more youthful.A proper exam and consultation will allow to assess you and treat you.

Dear EsmeLala,bottoming out occurs when the implant falls below the current breast crease or inframammary line. It's more likely to happen with inframammary incisions, which is why I try not to use the inframammary approach to any breast surgery.
Bottoming out can also occur if an implant is too large for the breast pocket. That is why it is important to choose an implant size that's correct for your body. I perform numerous measurements in the office to determine optimal implant size for my patient's bodies.
If you are concerned, please check it with your plastic surgeon for reassurance and to further discuss your options and possibility of revision.Daniel Barrett, MD

and you're not believing that, its time to invest in a second opinion so that you can have someone tell you what is wrong and who doesn't have any interest in trying to avoid a revision or more surgery.  When you are told your options, you can return to your surgeon with that info and try to get it done under the revision policy which should save your $$$.  But it appears you had tuberous breasts to start with and if you want better, a lift is really needed in addition to correct of a contracture if occurring and improving symmetry of volume.  And the lift and new implant(s) will certainly add to the costs.  

I would suggest waiting until you have not breast fed for 6 months, then go back to your surgeon. One implant appears to be sitting too low and will need to be raise, and the other implant may have a capsule. Also, you will probably need a lift. Once your breasts have completely settled down from breast feeding, usually by 6 months after stopping, this can be corrected.

Sorry for your problem and I would go on some complimentary consultations with experts and compare recommendations after a full examination and look at photos of similar patients and become fully informed about the desired procedure.  That said it appears you have capsularcontracture and ptosis.
