ABSTRACT

Cosmetic breast implants have become increasingly popular throughout the world. However, there is insufficient knowledge about the frequency and severity of local complications such as rupture and capsular contracture. A pilot study of 25 Finnish women with 50 cosmetic breast implants was organized to determine the feasibility of conducting a magnetic resonance imaging (MRI)-based study of rupture incidence. The pilot investigation included a clinical examination by a plastic surgeon, MRI scan, and self-administered questionnaire. The participation rate was 100%. Implants in our study represented a cross-section of the different generations of implants in Finland, with implant ages varying from 4 months to 20 years. The average implant size was 215 mL, typical in Finnish cosmetic surgery. MR images were evaluated by two independent readers. The first reader diagnosed six implants with intracapsular rupture, while the other diagnosed all implants as intact. The procedures of the feasibility study proved successful, and the results demonstrate the importance of a rigid image evaluation protocol with employment of well-defined rupture criteria, as well as the benefits of several image readers.
