ABSTRACT
BACKGROUND: The autologous fat grafting is commonly used for reconstructive or aesthetic purposes. However, due to the huge variation in methods, its retention rate varies a lot. External volume expansion (EVE) has been used to treat recipient sites of fat grafting. Concerns have been raised regarding its efficacy and safety.
METHODS: We have searched PubMed, EMBASE, and the Cochrane Library for studies on EVE-assisted fat grafting published from 2000 to 2020. A meta-analysis was conducted to pool the retention rate. The incidence of complications was assessed for reconstructive or aesthetic purposes.
RESULTS: The 11 included studies involved 1152 patients with operations on 1794 breasts. Four studies were included in the meta-analysis. The pooled retention rate was 65% [95%CI 49, 79]. Eight stu dies reported the complications. The total complication incidence was 34%, which is 35% for the aesthetic group and 33% for the reconstructive group. The complication rate was not obviously different between the two groups.
CONCLUSIONS: The study shows that the EVE-assisted fat grafting has better retention rate than traditional fat grafting. However, the data showed that the complication rate was much higher in the EVE-assisted group.
