I had a saline breast implants 16 years ago. Should I get new implants before they deflate? Or should I wait?

Even though your implants are 16 years old there is no reason to replace them if they're giving you no difficulty.

I am glad your breast augmentation surgery well. My philosophy if your implants are not bothering you or causing obvious physical deformity then leave them alone. There is no hard and fast rule that they must be replaced at 10 years

As long as you like the way they look and feel there is no reason to change them.  If you're unsure I would recommend you have a consultation with a board certified plastic surgeon.Best Regards,Dr Gartner

Usually, unless there's a medical problem or aesthetic problem- as deflation for example-- which according to you --you do not have-- there's no need to exchnage the implants. But generally speaking, if you feel that your breasts sag and you're unhappy with they way they look--- you might be a candidate for a lift with a possible augmention with silicone implants. Seek an experienced Board Certified Plastic Surgeon for in person consultation.

Two choices: if they don't bother you and you like the appearance there is no problem in waiting until one ruptures as the saline will simply be absorbed.On the other hand it is more than likely that one will rupture soon and you may want to plan the replacement electively that fits the best time in your schedule. Both reasonable choices.
