Abstract
BACKGROUND: Although the use of acellular dermal matrix (ADM) has increased exponentially, debates regarding its safety are still ongoing. There have been several meta-analyses; however, potential learning curve effects of using ADM might affect their outcomes. The present meta-analysis reappraised the potential benefits and risks of ADM on the outcome of implant-based breast reconstruction using recent publications. METHODS: Electronic databases were searched to identify relevant studies comparing the outcome of ADM use with traditional submuscular technique, which were published from 2011 to 2014. The relative risks of postoperative complications and mean difference of expander dynamics between the two groups were computed. RESULTS: A total of 23 studies representing 6199 cases were analyzed. There was one randomized controlled study and three prospective cohort studies. The use of ADM significantly elevated the risks of infection, seroma, and mastectomy flap necrosis, but did not affect the risks of implant loss, unplanned reoperation, and total complications. The risks of capsular contracture and implant malposition were significantly reduced by the application of ADM. The ADM allows for significantly greater intraoperative expansion and reduced frequency of injection to complete expansion. CONCLUSIONS: According to this meta-analysis, the increasing risks for serious complication and overall morbidity related to ADM use might not be remarkable, while its benefits for preventing late complications and improving expander dynamics might be appreciable. Although future well-controlled studies would be required, the implant-based breast reconstruction using ADM may be reliable and advantageous.
