Abstract

Insights

The McGhan Style 153 double-lumen breast implant has a high rupture rate of 19.1%. Most ruptures occurred peripherally, likely due to shell flaws, not posterior tears.

Area of Science:

  • Plastic Surgery
  • Biomaterials Science
  • Medical Device Analysis

Background:

  • The McGhan Style 153 double-lumen breast implant was recalled in 2005 due to a high rupture rate.
  • The failure was linked to posterior shell tears at the bonding site of the inner and outer layers.

Purpose of the Study:

  • To determine the current rupture rate of the recalled McGhan Style 153 double-lumen breast implant.
  • To describe the failure mechanism of this specific breast implant model.

Main Methods:

  • A retrospective review of 97 patients (157 implants) who received the Style 153 implant.
  • Analysis of intraoperative findings and photographic evidence of ruptured implants.

Main Results:

  • The overall rupture rate was 19.1% after a mean follow-up of 82 months.
  • Ruptures were most commonly detected by physical examination (60%) and occurred at the implant periphery (63%).
  • Posterior tears at the inner bladder bond accounted for only a small fraction of ruptures.

Conclusions:

  • The Style 153 double-lumen breast implant exhibits a significant rupture rate of 19.1%.
  • Peripheral ruptures are predominant, suggesting fold flaws in the implant shell as the likely cause of failure.
  • The initially suspected posterior tear mechanism appears less common than peripheral shell failure.
