To review the range of local and systemic complications attributed to silicone breast implants and to evaluate the epidemiologic literature on these complications.
Epidemiologic studies of the potential risks of silicone breast implants identified by MEDLINE search and literature review.
Epidemiologic studies with cohort, case–control, and cross-sectional designs. When epidemiologic studies were unavailable (as for estimates of local complications), case series were reviewed.
Epidemiologic studies evaluated for methodologic quality, including such characteristics as study design, sample size and selection, determination of silicone exposure and outcome variables, and duration of follow-up.
The epidemiologic literature on the potential complications of silicone breast implants has concentrated primarily on connective tissue disorders and cancer. Estimates of the true incidence of local complications, such as rupture, capsular contracture, and breast pain, are unavailable. Studies of scleroderma and other defined connective tissue diseases suggest that implant recipients have no substantially increased risk for these disorders; however, the epidemiologic literature is insufficient to rule out an association between breast implants and connective tissue disease-like syndromes. Overall, the rate of breast cancer does not seem to be increased in women with silicone breast implants. However, the risk to women as they reach the postmenopausal years is not yet known.
Information is insufficient to adequately advise women who currently have or are seeking to obtain breast implants about the overall risk of these devices. No epidemiologic study has indicated that the rate of well-defined connective tissue disease or breast cancer has greatly increased in women with silicone breast implants, but no studies have ruled out a moderately increased risk for these diseases. No studies have adequately addressed the crucial issue of local complications such as rupture and capsular contracture, although evidence increasingly points to a higher risk for rupture as implants age.
