Techniques and Outcomes in Fat Grafting: Using Evidence to Determine Fact or Fiction.

METHODS: A comprehensive literature search was performed using the following databases: the Cochrane Central Registrar of Controlled Trials (CEN-TRAL), Ovid MEDLINE, Ovid EMBASE , Ovid CINAHL and Google Scholar. The following key words were then searched: “fat grafting”, “autologous fat grafting”, “autologous fat transfer.” We then assessed each modality individually, from relevant articles, for the level of evidence that exists and whether the majority of evidence supports or refutes it.
