Fat grafting in breast surgery: a retrospective single-breast centre 6-year experience.

[PURPOSE] In recent years, fat grafting has gained importance as a valuable technique in breast surgery. As a breast center that has embraced this approach, we aimed to investigate the indications and complications of fat grafting.

[METHODS] In this retrospective study, we examined a total of 263 lipofilling treatments on 121 patients. Five groups were identified: the reconstruction group (72.7%), consisting of 24.8% autologous and 38% implant-based reconstructions after cancer, and correction of the tuberous breasts (10.7%). An almost equivalent group (10.7%), consisted of patients treated for cosmetic reasons. Patients after breast-conserving therapy amounted to 16.5%. Twenty patients (16.5%) were treated to alleviate pain.

[RESULTS] No major complications, and no cancer recurrence or metastasis were observed. One case of infection occurred at the injection site (infection rate: 0.38%). ANOVA showed statistically significant results for age (p < 0.001) and mean fat volume (p = 0.001). Posthoc analysis showed that the mean age of the tuberous group (21 years) was significantly smaller compared to all other categories (p < 0.001). Post-hoc analysis for fat volume indicated that the mean value for the cosmetic category (447.08 cc) was significantly greater than that of the breast-conserving and implant reconstruction categories (p = 0.009 and p = 0.030, respectively), while not significantly different from the tuberous and autologous reconstruction categories (p = 0.928 and p = 0.648, respectively).

[CONCLUSIONS] Lipofilling has proven a valuable adjunct in reconstructive and aesthetic breast surgery with a low complication profile. The versatility of this low-cost technique and the low rate of complications make it a powerful asset of modern breast centers.
