Abstract:
Objective:To preliminarily evaluate the outcome of fat grafting breast augmentation using filtration-adsorption technique.Methods:Patients undergoing autologous fat grafting (AFG) breast augmentation between July of 2020 and March of 2021 were retrospectively reviewed at Breast Plastic and Reconstructive Surgery Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, Peking Union Medical College. Patients with complete data who followed up for at least 3 months were included. The lipoaspirates were processed with filtration-adsorption technique and AFG breast augmentation were performed (filtration-adsorption group), and then sedimentation method which was commonly used clinically was set as the control group (sedimentation group). During the follow-up, breast palpation and ultrasound inspection were performed, and the breast volumetric change between preoperative and postoperative was quantitatively compared by three-dimensional scanning technique. Demographic and surgical details were statistically analyzed. Postoperative breast volume retention rates and complication rates were calculated and compared. Normally distributed continuous variables were described in the form Mean±SD, and t-test was used for analysis. Non-normal distributed continuous variables were described in the form of M ( Q1, Q3) and analyzed by Mann-Whitney U test. The classified data were analyzed by Fisher exact probability test. Results:A total of 20 female patients (40 breasts) were included, including 10 patients (20 breasts) aged (31.4±2.5) years in sedimentation group and 10 patients (20 breasts) aged (28.5±4.4) years in the filtration-adsorption group. The fat injection volume in the filtration-adsorption group was 151.1 (125.0, 175.0) ml, and 165.0 (151.3, 196.3) ml in sedimentation group, respectively, with no statistical significance ( P>0.05). The breast volume retention rate in filtration-adsorption group was (62.93±14.06)%, which was significantly higher than that in sedimentation group (24.97±11.02)% ( P<0.01). During postoperative breast ultrasound examination, 2 breasts in sedimentation group had palpable nodules (< 6 mm), 1 breast had ultrasonically detectable but clinically inaccessible nodules (< 4 mm), while only 1 breast in the filtration-adsorption group had an oil cyst (4 mm×2 mm). The complication rate in the filtration-adsorption group was lower than that in sedimentation group[5.0%(1/20) vs. 15.0%(3/20), P>0.05]. Conclusion:The filtration-adsorption technique is an ideal method for fat grafting, which would multiply the volume retention rate in large-volume AFG breast augmentation and reduce the rate of complications.
