When Should an Old Saline Implant Be Exchanged?
An intact saline implant has no fixed expiry date, but deflation, capsule problems or changed cosmetic goals — not the calendar alone — are what usually prompt an exchange.
Saline implants fail loudly. When the shell or valve gives way, the salt water is absorbed by the body and the breast visibly shrinks within days — which makes surveillance far simpler than with silicone. The harder question is whether an aging implant that still looks fine should be swapped preemptively.
Replace on a schedule, or replace on a signal?
Regulators do not set a mandatory exchange age, but they are equally clear that implants are not lifetime devices: shells and valves wear, and the likelihood of deflation climbs as the years accumulate. How fast a given implant ages differs from device to device and from person to person, so a fifteen-year-old implant in one chest may be quietly intact while a younger one has already failed.
In practice the exchange conversation starts with a signal: a deflating side, worsening capsular contracture, malposition, or simply a size and shape the patient no longer wants. Some choose a preventive swap when another breast operation is planned anyway. Weigh the age of the device and your own priorities in a consultation with a board-certified plastic surgeon.
