Acellular Dermal Matrix (ADM) is used in most post-mastectomy implant-based breast reconstructions in the United States. It is believed to be safe, despite a slightly increased complication rate. Though never established in a unifying study, the primary advantage of ADM is believed to be an enhanced aesthetic result, thus justifying the added expense. The purpose of this study was to assess the aesthetic benefits of ADM in expander-to-implant breast reconstruction.
A systematic review adhering to Preferred Reporting Items for Systematic Review (PRISMA) methodology was performed including all original studies examining aesthetic outcomes of expander-to-implant breast reconstructions with ADM compared to muscular coverage. Direct-to-implant and prepectoral studies were excluded from the evaluation. The results were aggregated and reported as a summary.
Among 883 studies identified, 49 full manuscripts were reviewed and nine manuscripts ultimately met inclusion criteria. All nine studies were not randomized. Of these, three manuscripts (1448 total patients) evaluated reconstruction aesthetic outcomes by patient satisfaction while six manuscripts evaluated the aesthetic outcomes by external observer (504 total patients). None of the manuscripts evaluating patient satisfaction reported a difference between ADM and muscular reconstruction. Five of the six manuscripts using objective outcomes demonstrated significant improvement in aesthetic outcome in the ADM group.
Though little evidence exists evaluating the aesthetic benefits of ADM for expander-to-implant breast reconstruction, the data suggest that objective observers consider ADM-assisted expander-to-implant breast reconstructions aesthetically superior to reconstruction with only muscular coverage, but patients appear to be equally satisfied with both reconstructive options.
