Do saline/silicone implants cause fungus or mold inside the body?

I have heard of the concern of mold forming in saline implants, but I have never actually seen it nor have I heard about it from another surgeon.  It must be extremely rare and the risk quite low.

The answer is NO.  Breast implants are the most studied medical devices in the history of humanity.  Provided they are used as they were designed to be used by appropriately certified surgeons in appropriately accredited facilities, they are safe, and unassociated with micro-organisms of any type.  That being said, we humans live in a world of micro-organisms, including those that make their homes in our gastro-intestinal tract, under our fingernails, in our respiratory tract, inside our sebaceous glands, and even inside the lactiferous ducts of our breasts.  When implants are associated with microbes, the source is most often the host.

and you may be referring to some case reports where old saline implants were removed and had organisms growing in the saline.  At this point, surgeons used closed systems to fill saline implants and gel implants are manufactured under the most stringent of conditions.  So implants do not harbor molds or fungus anymore.

Surgical infections can occur with any surgery, and they are not exclusive to breast implants: it can happen with orthopedic, cardiac and any type of surgery.Generally, the implant becomes contaminated AT THE TIME OF SURGERY. The contaminated implant can rest peacefully for months to years before any overt signs of infection manifest.Once an implant is infected, it is obligatory to remove it and wait for 6 months or so before putting a new one in its place. This allows the body to 'clean up' the infected breast tissue before adding the replacement implant.Having said all this, I should emphasize that implant infections are EXTREMELY rare. I have had one infection in 15 years, and in this case the patient neglected to take her antibiotics.I hope this helps!

Having mold/fungus grow inside of saline implants is highly
unlikely and very rare. I have never
seen a case in my practice but it can happen.
There are two ways that saline is
put into implants. This first method is
an open fill system where sterile saline is poured in a sterile container on
the surgical field and is exposed to air.
It is then drawn up via a syringe and injected into the implants. Even though the solution and field are
sterile, it is the exposure to air that can lead to mold formation in the
implant. The second and more common
method is to use a close filling system where the saline goes directly from a
closed IV bottle into the implant through connected tubing. This method is more sterile since the saline
is not exposed to the air, highly minimizing the risk of mold formation. If the implant is placed correctly and using
sterile technique the risk of mold formation is extremely rare. Make sure that you have procedures completed
by a board certified plastic surgeon to further minimize this risk.

The short answer is extremely rare and the reasons are:1) breast implants are manufactured under the highest sterile standards and our regulated/monitored by Governmental agency's.  They have/are under constant monitoring.2)Board Certified Plastic Surgeons have gone through extensive infection prevention training. Most Plastic Surgeons will give peri operative antibiotics and intra operatively, prior to insertion of the implants, rinse out the pocket with a solution that contains several antibiotics. 3)Accredited/certified Surgical Operating rooms have to meet very high standards to attain accreditation are required to perform rigorous and continuous  sterility checks and monitor surgical outcomes as they relate to infections. For more detailed information please go to the manufactures websites: Allergan.com, Mentor.com, and Sientra.com.Lastly,  make sure your Plastic Surgeon is certified by the American Board of Plastic Surgery and he/she operates in a accredited operating room.
