Am I bottoming out? Lateral malposition? (Photo)

Hi there! It does appear that your left implant is below your incision which is a good indication that the implant has migrated lower than anticipated. This is a subtle “bottoming out” as you were referring to. A pocket repair and use of internal bra scaffold can help repair this concern! I would return to your plastic surgeon and see what they think or offer

This could be easily addressed with horizontal skin excision to make the nipple to fold distance equal on both sides. It appears that the scar planning was a bit too high. The scars have now displaced on the lower pole of the breasts (worse on the left than right). There is also a slight "bottoming out" of the left breast, which could be reinforced at the time of the excess skin removal with the horizontal resection.

It does seem like your left implant is positioned somewhat low. You could consider returning to your plastic surgeon for and evaluation and an opinion whether a small revision surgery is appropriate.
