What does the 77.48% retention rate for SVF breast augmentation mean?
The 77.48% figure comes from a 2023 study in Annals of Plastic Surgery authored by SC301's representative director: among 384 women who had SVF-enriched breast fat grafting, the average retention measured in the left breast was 77.48% in the 102 patients followed to 18 months. It is a single-center, provider-authored result, not a general average for all SVF fat grafting, and should be read with its study design.
Answer
The same study reported 78.65% retention at 3 months (n=384) and 77.17% at 6 months (n=273). Retention was lower in the right breast (60.35%) and in stiff breasts, and higher with more SVF cells. No independent randomized comparison was identified as of September 2026.
