Left breast much narrower than the right (Photo)

With the implant being on the smaller side, I wonder if this difference reflects an asymmetry of your natural breasts. If so, it could be improved with a slightly larger/wider implant seated a bit more medially (toward the center). The other scenario could be an underdeveloped pocket toward the center. The fix might involve correcting that and different implants to account for a slight volume asymmetry. Your original surgeon will have the best handle of what is going on. Good luck!

Dear Fierce984128,
I understand your concern and it is quite normal to be concerned about the outcome following a breast augmentation surgery. However, you are still in the very early stages of the healing process at 1 days post op.You will need to be patient at this moment and follow what your surgeon has instructed you to do post operatively.At the early stage of the healing process, the tissues around the implants are still swollen. Once the swelling subsides and the implants drop to their final position, you will be able to see the final result of your breast augmentation surgery.

Hello,
To provide an accurate assessment, it’s important to see what your breasts looked like before the procedure. If there was already some asymmetry between your breasts before surgery, differences in the location and shape of the pockets created during the procedure can cause a significant difference in appearance. However, if there wasn’t a noticeable difference beforehand, the post-surgery disparity is usually due to uneven pocket creation or inadequate muscle release on one side when the implant was placed under the muscle.
