Seroma Formation in Pre-pectoral Implant-Based ADM Assisted Breast Reconstruction: A Comprehensive Review of Current Literature.

ABSTRACT

In the field of implant-based breast reconstruction (IBBR), the most recent and successful progress has been the evolution of the prepectoral approach through the use of acellular dermal matrix (ADM). ADM-assisted breast reconstruction is now gaining a foothold as standard practice, but its advantages are often clouded due to discouraging studies reporting increased seroma formation. The origin of the serum accumulation still remains unclear, but it has always been the most frequent early complication in breast reconstruction, thus proving to be crucial to address since it can lead to further complications. Using a standardized approach to obtain high-quality scientific evidence, the aim of this review is therefore to investigate the occurrence of seroma in breast implant-based reconstructive surgery and its possible relation with matrices. We conducted the review investigating only pre-pectoral implant positioning and one specific ADM (BraxonÃÂî) which is the one who has the highest number of cases in literature. nterestingly, ADM does not appear to be causative of seroma formation, but a surgery-related origin is discussed. In this setting, a series of rigorous guidelines have therefore been identified and analyzed to allow not only the treatment, but also the prevention of seroma, thus leading to a reduction in the incidence of this frequent problem.
