Percentage volume maintenance in autologous fat graft breast augmentation

Abstract

Objective To analyze factors of volume maintenance percentage after autologous fat grafting breast augmentation. Methods From March 2011 to December 2014, 39 patients were included. Age, BMI, donor site, breast preoperative volume, whether or not application of Brava and water-jet-assisted liposuction were collected as variables. We performed multivariate regression and univariate regression analyses in a general linear regression model and multilevel linear regression model to identify significant factors. Results The mean percentage of volume maintenance was (34±12)%. In univariate regression analysis, rate of volume maintenace was decreased 3.3% as increase of age per 5 years; Brava application increased volume maintenace, compared with donor sites of the back and abdomen 8.4% (40.7% vs 32.3%, P<0.05), application of leg fat increased by 9.6% of volume maintenace (39.1% vs 29.5%, P<0.05). In the multivariate regression analysis, Brava use increased volume maintenance of 6.2% (P<0.05); use of leg fat increased by 6.0 % of volume maintenace as compared with donor sites of the back and abdomen (P<0.05). Conclusions The age, Brava, and donor site are significant impact factors to percentage volume maintenance in autologous fat graft breast augmentation.
