Comparison of Outcomes Using AlloDerm Versus FlexHD for Implant-Based Breast Reconstruction

BACKGROUNDProsthetic reconstruction using human acellular dermis (ADM) is a common practice in breast reconstruction. AlloDerm and FlexHD are two different forms of ADM, each with unique characteristics. No studies have directly compared the postoperative complications of these 2 products. METHODSThe outcomes of 547 consecutive implant-based breast reconstructions were reviewed. RESULTSReconstruction was performed in 382 consecutive women (547 total breasts), employing mostly immediate reconstruction (81%). Mean follow-up was 6.4 months. Among immediate reconstructions, 165 used AlloDerm and 97 used FlexHD. Complications were similar by univariate analysis. In multivariate analysis, smoking and higher initial implant fill were risk factors for delayed healing. The use of FlexHD, single-stage reconstruction, and smoking were independent risk factors for implant loss. CONCLUSIONSThere is no significant difference in the complication rates between AlloDerm and FlexHD in immediate breast reconstruction. Multivariate analysis suggests that FlexHD may be a risk factor for implant loss.
