Answer

The acellular dermis matrix (ADM)-assisted expander-implant technique involves the use of tissue expanders or implants. In this technique, the surgeon disinserts the pectoralis major and shapes the lower pole of the breast, essentially using the acellular dermis as a sling. This allows increased control over expander placement, leading to better inframammary fold definition and, ultimately, a more natural soft tissue shape. [1, 4, 5, 6]

In addition, the use of acellular dermis creates a larger implant pocket, allowing greater intraoperative tissue expander fill volumes and an accelerated expansion process. [1, 2] After expansion, either expanders are exchanged for a permanent implant or they are removed and the breast is reconstructed with an autologous flap. Given sufficiently large mastectomy flaps, single-stage, direct-to-implant reconstructions have also been reported. [4, 5]
