Chemical and Structural Characterization of Several Mid-Term Explanted Breast Prostheses

Area of Science:

• Biomaterials Science
• Medical Device Analysis
• Public Health

Background:

• The Poly Implant Prostheses (PIP) scandal highlighted risks associated with non-medical grade silicone in breast implants.
• Thousands of patients required explantation, leading to significant healthcare costs and public concern.

Purpose of the Study:

• To analyze explanted breast implants using a multidisciplinary approach.
• To identify organic and inorganic contaminants within the implants.
• To assess the potential health implications of material degradation and contamination.

Main Methods:

• Explantation and analysis of sixteen different breast implants.
• Utilized Fourier Transform Infrared Spectroscopy (FT-IR).
• Employed Mass Spectrometry with Inductively Coupled Plasma (ICP-MS) and Gas Chromatography-Mass Spectrometry (GC-MS).
• Conducted tensile testing for structural integrity assessment.

Main Results:

• All analyzed explanted breast implants contained traces of organic substances (fatty acids) and inorganic substances (metals like Fe, Cr, Pt, Na).
• Detected contaminant levels were below established danger thresholds.
• The presence of these substances suggests potential for bioaccumulation and tissue contamination over time.

Conclusions:

• Continuous medical surveillance is crucial for patients with breast implants.
• Monitoring the aging process of implant materials is essential to detect potential long-term health risks.
• Further research into the long-term effects of low-level contaminant exposure is warranted.
