BACKGROUND: The current standard for breast augmentation involves placement of an implant. As an alternative, surgeons have been exploring breast augmentation with autologous tissue in the form of injectable fat.
OBJECTIVES: The authors explore the efficacy and safety of lipoaugmentation of the breast, with specific interest in volume changes, fat retention, overall aesthetic improvement, and patient satisfaction.
METHODS: Direct measurements, 2- and 3-dimensional images, mammograms, and magnetic resonance imaging (MRI) were obtained preoperatively from 10 consecutive patients undergoing augmentation mammaplasty with autologous fat transfer. These measurements were repeated 1 year postoperatively. Postoperative photo imaging was conducted at 3-month intervals for 1 year. Efficacy was evaluated by determining the volume of fat retention 1 year after the procedure with 3-dimensional imaging, standard breast MRI volume measurements, and subjective aesthetic comparisons.
RESULTS: The average amount of fat injected was 236 cc (90-324; SD, 69.8) in the right breast and 250 cc (90-300; SD, 65.1) in the left. The mean volume change based on 3-dimensional imaging was 85.1 cc (36% retention) for the right breast and 98.1 cc (39.2% retention) for the left. The mean volume change based on MRI measurements was 30.0 cc (39.8% change) on the right and 29.3 cc (38.1% change) on the left. Blinded observers found substantial improvement in 1 patient (10%), moderate improvement in 5 patients (50%), and minimal to no improvement in 4 (40%). Overall patient satisfaction was high, as measured by the abbreviated BREAST-Q. Radiologic abnormalities and artifacts were common and required additional imaging.
CONCLUSIONS: Objective breast enlargement in this study was modest but yielded disproportionately high subjective patient satisfaction reports.
LEVEL OF EVIDENCE: 2.
