What might I expect with implant removal and no lift? (Photo)

The smaller the implant and the less the amount of time it has been since placement, the greater the chance the breasts will return to their preoperative state. It is very difficult to predict breast size
following explant b/c breast implants and weight fluctuations over time tend to thin tissues, cause a decrease in size, and create more droop.  
Usually removing the implants and performing the lift at the same time makes the most sense as some patients clearly need a lift and only want to go through one surgery.  If you are borderline, it is not unreasonable to remove the implants and then observe a waiting period of six months before the determination for breast lift is made. This will give your breasts time to bounce back and your PS time to determine what type of lift, if any, or a breast fat transfer is necessary for you to reach your goals.

You did have some sagging prior to implants and will have some after removal. You could consider a lift, or even skin tightening with radiofrequency like ThermiTight. Implants did stretch your tissue and did thin your own breast tissue some.

I'm sorry to hear of the issues you have had with your breast augmentation.  After removal and complete healing you can anticipate your breasts to return to a similar look to what you had prior to surgery with a little more looseness to the skin.  I encourage you to meet with a board certified plastic surgeon to discuss your surgical goals.
