Is It Normal to Feel the Valve of Breast Implants?

The modern saline implant valve complex is rather flat and non-projecting and located at the topmost portion of the implant. As a result, they are very rarely felt and only in some women with almost no breast tissue in whom the implants were placed over the muscle.
A better option in such patients are silicone gel implants which are lighter, ripple less and which have no valves.

It is not unusual for a saline implant placed above the muscle in a thin woman to have a palpable implant valve.  If this is your situation, your options include moving the implant to a submuscular location and changing to a silicone implant which has no valve.
