Both silicone and saline implants have the risk of rupturing or leaking once placed inside the body. Surgery may be required to safely remove and replace the damaged implant. Saline implants placed over the pectoral muscle can sometimes cause skin rippling due to a lack of tissue covering the implant, which results in a wavy texture in the skin. Other risks include reduced nipple sensation, scar tissue, and capsular contracture causing a hardened texture. You should contact your doctor immediately if you feel a difference in your breast implant shape after your recovery.
