The overall objective of this proposal is to conduct a randomized-controlled study to determine whether treatment with dehydrated human amnion/chorion membrane (dHACMs) allografts can improve NAC viability in patients undergoing nipple sparing mastectomy (NSM). dHACM allografts are commercially available tissue membranes with biocompatible extracellular matrix and growth factors that have been shown to improve wound healing in patients with chronic and lower extremity wounds. To date, no study has evaluated the impact of dHACMs on NAC preservation following NSM. Investigators hypothesize that subareolar surgical implantation of dHACM allografts at time of NSM will reduce NAC necrosis and improve viability.
