Bacterial Biofilm Formation on the Breast Implant Capsules

Category: | Posted on: April 27, 2020 Updated on: August 4, 2020 | Author:

A biofilm is a group of bacteria that can adhere to the surface of a breast implant through the formation of a slimy glue-like substance. The formation of these biofilms around an implant may have a link with subclinical infections, capsular contracture, and other systemic symptoms.

Signs and How to Detect Biofilm on Breast Implants

It is not always evident if a biofilm is present around a breast implant. Patients may have subtle signs of pain, breast distortion, and other subtle symptoms (e.g., feeling tired all the time).

Unfortunately, there are no blood or imaging tests that can diagnose whether or not a biofilm has developed around breast implants. On physical exam, the breast implant may feel firmer than expected, or the breast may be visibly distorted. Diagnosis is made by physical exam, your symptoms, and whether or not the symptoms have improved with other forms of medical treatment.

Risks of Bacterial Biofilm on Breast Implants

Biofilms allow the bacteria to survive on the surface of the breast implant and also provide a barrier against antibiotics. Biofilms can cause an acute infection, but it can rarely cause an immediate problem.

Over time, however, biofilms have been linked to the following:

  • Formation of Capsular Contracture – A significant tightening of the connective tissue that usually forms around a breast implant
  • Breast Distortion
  • Anaplastic Large Cell Lymphoma (ALCL) – Usually, in connection with textured breast implants
  • A variety of Other systemic Symptoms – Fatigue, Malaise, Chronic Inflammation

Will it Spread to the Unaffected Breast?

It is unlikely that biofilm could spread to an unaffected breast. A biofilm usually forms when the implant is exposed to bacteria at the time the implant was initially placed.

Treating the Affected Breast Implants

At this time, there are no medications that can eliminate a biofilm after it has formed. The slimy part of the biofilm, forms a protective barrier around the bacteria, making it difficult for any medications to penetrate the barrier.

However, when we suspect that a biofilm has formed around your implant, and it is causing your symptoms, we recommend the total removal of the implant with the entire capsule. Depending on your symptoms, we may also prescribe antibiotics after the procedure.

Preventing the Risk of Bacterial Biofilm Formation

Biofilms usually form when implants are exposed to bacteria at the time of the initial placement. These bacteria can come from the environment, a patient’s skin, or breast tissue. The best way to prevent biofilm formation is to keep the implant away from being exposed to bacteria and avoid using implants where bacteria can easily adhere.

Here are a few things we do to prevent the implants from bacteria:

  • Patients are given intravenous antibiotics at the start of a procedure
  • Only the surgeon will handle the implant using new gloves
  • We reduce the amount of time the implant is exposed to the outside environment
  • The implant is soaked in an antibiotic solution
  • We use a barrier device and nipple shields to prevent contact between the patient’s skin
  • Keep our patients on antibiotics for a few days after the implant is placed

What does MBAS do once the biofilm is removed?

At MBAS, we send the capsule for complete testing. This testing includes:

  • Complete pathologic analysis – The capsule is looked at in great detail with a microscope
  • Microbiologic analysis – The capsule is examined for the presence of bacteria
  • Cytology (in some cases) – Advanced study to look at specific characteristics of cells within and around the capsule
