Patients who choose saline implants tend to do so because they feel confident knowing that if the implant ruptures the saline that leaks into the body's tissues is safe. Saline is basically salt water, and it has many uses in medicine. Saline is often used to clean wounds, remove contact lenses, and help with dry eyes. Saline is injected into veins to treat dehydration, and it is also used to dilute other medications used intravenously. If a saline implant ruptures, the saline that spills into the breast tissue will be absorbed easily by the body. It will also be obvious that the implant is ruptured, as the breast with the ruptured saline implant will appear deflated.
On the other hand, saline implants tend to feel firm, and they may also feel less natural. Saline implants last the longest when they are maximally filled or even slightly overfilled. Underfilled saline implants will have wrinkles, and those wrinkles are weak spots on the implants that can lead to rupture. The firmness of a saline implant will be particularly evident in women who have little or no breast tissue. Saline breast implants can be used in women over age 18 years for breast augmentation, and in women of any age for breast reconstruction.
