Abstract
Background
Some studies have indicated that liposuction may cause breast enlargement. Fat redistribution to the upper body as a compensatory mechanism after liposuction has also been reported.
Objectives
To evaluate the possibility of secondary breast hypertrophy and fat redistribution after liposuction, breast size and upper body measurements were obtained and compared for women who did not gain weight postoperatively.
Methods
Eighty-two women who underwent cosmetic surgery, not including breast surgery, were enrolled in this prospective controlled study. Participants represented 1 of 3 procedure groups: cosmetic surgery not including liposuction (n = 24), liposuction (n = 41), and liposuction combined with abdominoplasty (n = 17). Breast measurements were obtained from standardized lateral photographs matched for size and orientation. Results were compared among the study groups.
Results
Postoperatively, there were no significant changes in mean body weight among the study groups. No significant increases in upper pole projection, breast projection, or breast area were found in patients treated with liposuction alone and those who received liposuction plus abdominoplasty. Upper body dimensions were unchanged except for a significant (P 1500 mL.
Conclusions
Results indicate that neither liposuction nor abdominoplasty produces secondary breast enlargement. Upper body dimensions are unchanged, consistent with findings of a previous study and contrary to the theory of fat redistribution.
