Interest of acellular dermal matrices in immediate breast reconstruction: Comparison of quality of life and complications with and without matrix.

Since 2001, acellular dermal matrices have been increasingly used in immediate breast reconstruction (IBR) because they allow for the placement of the ideal-sized definitive implant in one step. They are used in both retropectoral and prepectoral prosthetic breast reconstructions. The aim of this study was to evaluate the impact of dermal matrices on the quality of life and on complications. Two surveys were used to evaluate the quality of life: the BREAST-Q V2.0© and the QuickDASH. The surveys were sent to all patients who had an immediate prosthetic breast reconstruction at a University Hospital Center from 2010 to 2020. A case-control study was performed for comparison of responses between the "Matrix+" and "Matrix-" groups. Seventeen IBR with matrix (23.6%) and 55 IBR without matrix (76.4%) were analyzed. Patients in the "Matrix+" group had a better quality of life in terms of sexual well-being (p = 0.038) and a significantly lower QuickDASH (p < 0.01). They had better breast satisfaction (p = 0.016) and better implant satisfaction (p < 0.01). The likelihood of encountering major complications later in time was more important in the group with matrix (p = 0.04). We found a satisfactory quality of life with scores of sexual well-being and satisfaction with the breast and the implants, and a better satisfaction with care thanks to the use of the matrices. However, due to a higher number of major late complications and a lack of follow-up, we believe that immediate prosthetic breast reconstruction with matrix should be discussed according to the comorbidities, medical treatments, and the vitality of the skin flaps of each patient.
