BACKGROUND: For women in the United States desiring implant-based breast reconstruction, the maximum volume of commercially available silicone breast implants has, to date, been 800 cc. The authors evaluated the safety of Mentor larger-size MemoryGel Ultra-High Profile breast implants (≥930 cc) in women undergoing postmastectomy breast reconstruction.
METHODS: This 10-year, multicenter, open-label, prospective, investigational study assessed the safety and effectiveness of larger-volume implants in women undergoing postmastectomy 2-stage primary or revision reconstruction. Three-year Kaplan-Meier curves and multivariable Cox regression analyzed the association between patient and treatment characteristics and surgical outcomes. The BREAST-Q was used to assess effectiveness at 3 years.
RESULTS: A total of 400 women were enrolled (225 primary and 175 revision reconstruction). Mean body mass index was 35.8 kg/m 2 ; 81% had a body mass index greater than or equal to 30 kg/m 2 . At 3 years, the cumulative incidence of postoperative complications (excluding rupture) was 63.0% (95% confidence interval, 58.1% to 67.9%). The reoperation rate was 24.5% (95% CI, 20.4% to 29.1%), and the explantation rate was 15.8% (95% CI, 23.5% to 19.9%). Independent predictors of complications included radiation therapy and a history of smoking. There were no significant associations between postoperative complications and implant volume greater than or equal to 1135 cc or less than 1135 cc. BREAST-Q scores at year 3 showed significant improvements from baseline in Satisfaction with Breasts, Psychosocial Well-Being, Sexual Well-Being, and Physical Well-Being (all P < 0.0001). The mean score for Satisfaction with Outcome was 79.9.
CONCLUSIONS: These 3-year results demonstrate that larger-volume silicone breast implants represent a safe and effective option for patients with larger breasts who are requesting postmastectomy implant-based reconstruction.
