Saline breast implants
Saline breast implants are filled with sterile salt water. Should the implant shell leak, a saline implant will collapse and the saline will be absorbed and naturally expelled by the body.
Saline breast implants provide a uniform shape, firmness and feel, and are FDA-approved for augmentation in women age 18 or older.
Round breast implants
Round breast implants have a tendency to make breasts appear fuller than form-stable implants. Higher profile options can achieve even more projection.
Because round implants are the same shape all over, there is less concern about them rotating out of place.
Smooth breast implants
Smooth breast implants are the softest feeling. They can move with the breast implant pocket, which may give more natural movement.
Smooth implants may have some palpable or visible rippling under the skin.
Silicone breast implants
Silicone breast implants are filled with silicone gel. The gel feels a bit more like natural breast tissue. If the implant leaks, the gel may remain within the implant shell, or may escape into the breast implant pocket. A leaking implant filled with silicone gel will not collapse.
If you choose silicone implants, you may need to visit your plastic surgeon regularly to make sure the implants are functioning properly. An ultrasound or MRI screening can assess the condition of breast implants.
Silicone breast implants are FDA-approved for augmentation in women age 22 or older.
