BACKGROUND External volume expander (EVE)-assisted autologous fat grafting is suitable for breast augmentation, but no large sample study in Asia confirms this method. OBJECTIVES In this study, we report our experience and outcomes in augmentation mammoplasty with EVE-assisted autologous fat grafting. METHODS A retrospective study was conducted in 305 female patients who underwent augmentation mammoplasty with EVE-assisted fat grafting between September 2012 and December 2020. Doctors used Crisalix for 3D imaging acquisition to measure the increase in breast volume to evaluate doctor satisfaction. The Preoperative Satisfaction with Breast and BREAST-Q questionnaires were used to assess patients' preoperative and postoperative satisfaction, respectively. RESULTS The 305 female patients were aged between 18 and 50 (mean, 35.9). Among them, 68.52% were "very satisfied", 18.69% were "somewhat satisfied", 11.15% were "somewhat dissatisfied", and 1.64% were "very dissatisfied" based on BREAST-Q analysis, whereas 100% were dissatisfied according to the Preoperative Satisfaction with Breast questionnaire. Doctors used Crisalix to measure the increase in breast volume to evaluate doctor satisfaction. The results showed 76.01% had an increase in breast volume of 150-250 mL or over 250 mL and were "satisfied" and "very satisfied", respectively, 21.64% had an increase of 50-149 mL and were "somewhat satisfied", and 2.30% had an increase of less than 50 mL and were "dissatisfied". There were no complications, such as obvious fat liquefaction, infection or fat embolism. CONCLUSIONS Augmentation mammoplasty with EVE-assisted fat grafting is effective and satisfying in China. Crisalix for 3D imaging acquisition is convenient and effective in measuring breast volume.
