Regional analgesia has been increasing in popularity due to its opioid- sparing analgesic effects and utility in multimodal analgesia strategies.

 Several regional techniques have been used in plastic surgery; however, there is a lack of consensus on the indications and the comparative efficacy of these blocks.

 The goal of this review is to provide evidence-based recommendations on the most relevant types of interfascial plane blocks for abdominal and breast surgery.

 A systematic search of the PUBMED, EMBASE, and Cochrane databases was performed to identify the evidence associated with the different interfascial plane blocks used in plastic surgery.
