5’10, 145lbs, silicone 345cc R & 330cc L - does this look like lateral displacement? (Photos)

Dear Reliable330303,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Yes, you have lateral displacement. Your implants were placed behind the muscle and when the muscle contracts the implants extrude inferiorly and laterally. This is a normal event after implants have been placed. It is not because the implants are too small. Larger implants would make the situation even worse. If you want to correct this, you will need to reinforce the implant pockets laterally. Sometimes doctors use mesh or sutures. The pockets needs to be dissected more medially. You will need to reposition the nipple-areola complex more medial as well.

Best Wishes,

A front view standing photo would be very helpful., However, all breasts do fall to the sides when laying down. if you do not like this, your lateral pockets can be tightened. I do not suggest going larger because your frame and tissue will not support heavy implants. Implants behind the muscle do get pushed to the sides when laying down.

Based on your posted photos that are only in the prime position without upstanding upright position, I would recommend a virtual consultation, but appears like you have slight lateral displacement and the breast implants are I agree with you might be a larger size going up at least 50 to 100 cc per side. Again best of virtual concert with expect fees to range for correction of lateral displacement by capsule or procedure and exchange of implants Would be $8000-$12,000
