Letter to the Editor: The Efficacy of Cell-Assisted Lipotransfer Versus Conventional Lipotransfer in Breast Augmentation: A Systematic Review and Meta-Analysis.

This is a letter to the editor about a meta-analysis titled "The efficacy of cell-assisted lipotransfer versus conventional lipotransfer in breast augmentation: a systematic review and meta-analysis" by Li and Chen published in the year 2021. The most frequently performed aesthetic procedure is breast augmentation surgery. In breast augmentation, cell-assisted lipotransfer (CAL) has received high recognition due to its positive outcomes. There are controversies in the medical literature on the use of CAL for breast augmentation. This meta-analysis by Li and Chen has concluded that CAL using ASC was superior to other methods as it improved fat survival rate in breast augmentation. We have written this letter to the editor of the Aesthetic Plastic Surgery journal about this meta-analysis because of its impactful information provided by this study to the medical literature for breast augmentation surgery using cell-assisted lipotransfer.
