“…This evolution is in part due to the conflicting evidence on whether ADM improves or reduces capsular contracture rates, and increased or null association with infection, seroma formation, and implant loss ( 5 , 21 - 25 , 33 - 38 ). There has also been an evolution of where ADM is applied, implant placement, and implant device type ( 32 ).…”

Background Acellular dermal matrix (ADM) has been the go-to biomaterial in post-mastectomy breast reconstruction, particularly in pre-pectoral reconstruction. ADM is thought to decrease capsular contracture, control the pocket, and increase soft tissue, but may yield more complications. This study evaluated whether ADM is even needed. Methods All patients undergoing immediate breast reconstruction with pre-pectoral tissue expander (TE) or direct-to-implant (DTI) after nipple-sparing mastectomy (NSM) by the senior author between April 2013 and January 2021, were included in this study. Cohorts were stratified into breasts with ADM or no-ADM. Complications within 30 days post-operatively were analyzed. Results A total of 115 pre-pectoral reconstructions were performed in 66 patients. ADM was applied to 75 breasts. TEs were used in 80 breasts and DTI in 35 breasts. Controlling for implant type, breasts with ADM exhibited more nipple necrosis (28.0% vs . 10.0%, P=0.02). Controlling for ADM status, DTI compared to TE was associated with less necrosis of the nipple (11.4% vs . 26.3%, P=0.04), implant loss (5.7% vs . 38.8%, P=0.004), and surgery for any complication (14.3% vs . 27.5%, P=0.04). Conclusions Outcomes of prosthetic reconstructions with ADM and no-ADM were similar. DTI reconstruction was associated with less complications, which was likely due to intraoperative bias and placement of TEs more often in breasts with perceived poorer vascularity.
