Saline Breast Implant Reduction

If you would like to decrease the size of an implant, this will require another surgery.
You may be able to keep the same implant if you only want a small amount removed. For example, 25-50 cc, depending on the implant.
Implants have a range of saline they need inside in order to maintain their shape. If you go below this range, the implant will collapse on itself. This will depend on the implant you have and how much saline was put in during the initial surgery.
Thus, if you want to remove a large amount of saline from the implant, you will need to replace the implant for a smaller one.

You can adjust those implants by 50 cc, that is, if they were 325 filled to 375. This is not a significant reduction.
In general, I recommend a reduction by at least 100 cc to have a noticeable difference. At times also if you do a significant reduction you may also have to tighten the skin (do a lift-mastopexy). Good luck.
