Is the shape of my boobs parenchyma maldistribution? If so, how can I fix it? (Photo)

Judging by the photos, I would say you would need a breast lift. If you are happy with the volume that you already have then a lift would be all you need. You can opt for a lift and breast implants if you would like to add more volume, in particular in the upper part of the breast (upper pole).

Make certain you see a board certified plastic surgeon to discuss your surgical options.

Hope that helps.

Dear Original773513
based on your photo, it looks like you would benefit from breast lift. My preferred lift is a lollipop lift when a periareolar won't do (ie greater than 2cm lift required). The lollipop technique was created by a Canadian plastic surgeon named Elizabeth Hall-Findley and treats the breast as a three dimensional structure instead of two dimensions (anchor - lift). Most importantly it does not require the horizontal component scars that the anchor-lift requires and breasts appear much more natural, lifted, and less boxy. Lastly, the lift lasts longer because the lollipop doesn't rely on the skin to hold the breast up, its actually breast tissue thats being brought together to support the breast and hence improves longevity. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.
