Poly Implant Prothèse silicone breast implants: implant dynamics and capsular contracture

Area of Science:

• Plastic Surgery
• Biomaterials Science
• Medical Device Engineering

Background:

• Poly Implant Prothèse (PIP) breast implants were recalled in 2010 due to substandard silicone, leading to increased rupture risks.
• This study investigated the dynamics of PIP implants, focusing on gel bleeding, rupture, and capsular contracture rates and predictors.

Purpose of the Study:

• To analyze the implant dynamics of Poly Implant Prothèse (PIP) breast implants.
• To determine the incidence and risk factors for gel bleeding, rupture, and capsular contracture in PIP implants.

Main Methods:

• Eighty women with 152 PIP implants undergoing reoperation in 2012 were included.
• Demographics and Baker scores were retrospectively collected; pre- and post-operative implant volumes were calculated, and implant integrity was assessed intraoperatively.

Main Results:

• Implants removed after an average of 11 years showed 42% gel bleeding and 25% rupture.
• Gel bleeding correlated with increased post-operative implant volume. Implant rupture significantly increased the risk of capsular contracture.

Conclusions:

• PIP implant shells demonstrated excessive permeability, correlating gel bleeding with post-operative volume increase.
• Implant rupture was identified as a significant risk factor for developing capsular contracture.
