Lacking upper pole fullness. What should I do? (Photo)

It appears you have achieve a good outcome from the prior procedure. If you truly desire more upper pole fullness, fat transfers are one option. As things currently look good, I would suggest procrastinating on further surgery, until you are sure this change would be worth the additional trauma, risks, and costs.

I'm sorry you are unhappy with your result. For more upper pole fullness you can consider fat transfer, which has its own risks and benefits, or exchanging the implants for a higher profile. Going with larger implants means they will be heavier and may be quicker to sag. There are options, but also the risks/benefits to consider.
