    Abstract:
    BACKGROUND: Prepectoral implant-based breast reconstruction is gaining in popularity. Acellular dermal matrices are an integral part of prepectoral reconstruction. However, large quantities of acellular dermal matrix are required for total implant coverage, and the cost of acellular dermal matrices could be a deterrent to reconstruction. To minimize the cost, the authors have resorted to the use of a bioabsorbable mesh, GalaFLEX, as a partial replacement to acellular dermal matrices. This study evaluates the comparative safety of using a GalaFLEX-AlloDerm construct versus AlloDerm alone in prepectoral reconstruction. METHODS: Consecutive patients who underwent immediate, expander-implant, prepectoral breast reconstruction were included in this retrospective study. Patients were stratified into two groups: those who received the GalaFLEX-AlloDerm combination versus AlloDerm alone. In GalaFLEX-AlloDerm reconstructions, the lower third of the expander was covered by the AlloDerm, whereas the rest of the expander was covered by GalaFLEX. Complications following reconstruction were compared between the groups. RESULTS: AlloDerm alone was used in 128 patients (249 breasts) and GalaFLEX-AlloDerm was used in 135 patients (250 breasts). The rate of any complication was 7.6 percent in the AlloDerm-alone group and 6.4 percent in the GalaFLEX-AlloDerm group. The rate of infection, major skin necrosis, seroma, capsular contracture, prosthesis exposure/extrusion, and prosthesis loss were less than or equal to 3.0 percent in the GalaFLEX-AlloDerm group and did not differ significantly from those in the AlloDerm-only group. CONCLUSIONS: GalaFLEX bioabsorbable matrix is a less costly alternative to acellular dermal matrices in two-stage, prepectoral reconstruction with comparable safety outcomes. Further long-term data and clinical experience are needed to better understand the safety of this matrix for use in breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
