Skin-reducing mastectomy.

BACKGROUND: The authors propose a combined flap technique to reconstruct large and medium-sized ptotic breasts in a single-stage operation by use of anatomical permanent implants. METHODS: The authors enrolled 28 patients fulfilling criteria for skin-sparing mastectomy and presenting with ptotic breasts whose areola-to-inframammary fold distance was more than 8 cm. All reconstructions were performed as a single-stage procedure. After preoperative planning, a large area in the lower half of the breast was deepithelialized according to the conventional Wise pattern. Mastectomy was then carried out. To perform reconstructions, the inferomedial fibers of the pectoralis major muscle were dissected and sutured to the superior border of the inferior dermal flap. An anatomical implant was then inserted into the pouch, which was closed laterally with the previously harvested serratus anterior fascia. Skin flaps were finally closed down to the inframammary fold. RESULTS: The authors performed 30 procedures on 28 patients. The medium size anatomical implants was 433 cc. Twelve women achieved symmetrization in a single stage ending in a symmetric inverted-T scar. The overall complication rate was 20 percent, with four cases (13 percent) complicated by severe, extensive necrosis of the skin flaps requiring implant removal. CONCLUSIONS: Breast cancer treatment must nowadays optimize cosmetic results. This can be accomplished in selected cases by means of a single-stage operation that the authors call "skin-reducing mastectomy." The final scars imitate those of cosmetic surgery. Careful patient selection and improvement in the learning curve may reduce the complication rate.

Prevalence of rupture in inamed silicone breast implants.

BACKGROUND: Silicone breast implants have been used for decades and are arguably the most studied implantable device. However, the vast body of scientific literature has been unable to establish a definitive rupture rate. Various studies have evaluated implant rupture, but the meaningfulness of these data was confounded by the inclusion of different generations of implants and multiple manufacturers' implants and the selection of subjects who were already suspected of having ruptured implants. The authors' study was designed to acquire long-term rupture data specific to Inamed's third-generation silicone breast implants using magnetic resonance imaging technology. METHODS: A total of 106 women with at least one Inamed silicone breast implant (styles 40, 110, and 120) were enrolled in this multicenter, cross-sectional study. The majority received implants for cosmetic augmentation (n = 77, 72.6 percent), with a smaller number having undergone breast reconstruction (n = 11, 10.4 percent) or revision of previous breast implant operations (n = 18, 17.0 percent). Most subjects were Caucasian (n = 99, 93.4 percent) with a median age at implantation of 34 years (range, 18 to 70 years). Enrolled subjects underwent a physical examination and magnetic resonance imaging screening at one of five sites to determine the prevalence of asymptomatic rupture. RESULTS: A total of 199 implants were evaluated, with a median implantation time of 10.9 years (range, 9.5 to 13.2 years). Overall, 183 implants (92.0 percent) showed no evidence of rupture, 12 (6.0 percent) showed evidence of rupture, and four (2.0 percent) were indeterminate. All indeterminate evaluations were considered ruptures, providing a worst-case rupture prevalence of 8.0 percent. CONCLUSION: The study results establish a rupture prevalence rate of 8.0 percent at 11 years for Inamed's silicone breast implants.
