Complications after Breast Augmentation with Fat Grafting: A Systematic Review

Mathias Ørholt et al. Plast Reconstr Surg. 2020 Mar.

Abstract

Background: Breast augmentation with fat grafting is used as an alternative to breast implants. However, a systematic evaluation of the complication rates after fat grafting using only studies with consecutive patients has not previously been performed. In this study, the authors compiled studies reporting complication rates and radiologic changes in consecutive patients undergoing cosmetic breast augmentation with fat grafting.

Methods: Studies reporting on consecutive patients undergoing breast augmentation with fat grafting were included. Complication rates, radiologic changes, Breast Imaging Reporting and Data System assessments, and the number of patients undergoing revision surgery were extracted. Mean complication rates and radiologic changes were calculated with meta-analytical methods.

Results: Twenty-two studies with 2073 patients were included. The rates of major complications were low (hematoma, 0.5 percent; infection, 0.6 percent; and seroma, 0.1 percent). None of these patients needed revision surgery. The most frequent minor complication was palpable cysts in 2.0 percent of the patients; 67 percent of these were treated with aspiration. The radiologic changes in the patients after fat grafting were as follows: oil cysts, 6.5 percent; calcifications, 4.5 percent; and fat necrosis, 1.2 percent. The risk of being referred for additional radiologic imaging (e.g., to exclude malignant changes) was 16.4 percent, and the risk of being referred for biopsy was 3.2 percent.

Conclusions: The complication rates after breast augmentation with fat grafting are low and support fat grafting as an alternative to breast augmentation with implants. The rates of radiologic changes are high after fat grafting, but the changes do not seem to have any therapeutic consequences for the patients.
