Can You Add More Saline After Breast Implant Surgery?

Saline breast implants have a specified range of acceptable fill volumes, so the most you could add is a couple of teaspoons which wouldn't be noticable. From experience I recommend that if a patient wants to see a definite change in size it usually needs to be at least 100 cc, whether going larger or smaller. this would mean different implants.

Certainly with your current saline implants you can add more saline.  It is another procedure, but usually pretty easy to do.  However, adding 15cc will not make any difference.  To get any sort of difference, you need to add at least 30-40cc of saline, and if you are looking for a noticeable increase in size, you need at least 75cc.  With your current implants, you can actually fill those to 450cc without any problem.  Allergan has a very narrow range that they put on the implants, but they admit that they can be overfilled much more than that without endangering the implant.  I hope this helps.
