Abstract

Hybrid breast reconstruction combines free tissue transfer with implant placement. Various mesh products have been successfully used to secure the implant position in these reconstructions. In this study, the authors investigate the impact of mesh type on long-term outcomes following hybrid breast reconstruction.A retrospective analysis of all patients with at least 24 months of follow-up after immediate bilateral prepectoral hybrid breast reconstruction was performed. Univariate and multivariable regression analyses were used to evaluate long-term outcomes and compare breasts reconstructed with polyglactin mesh versus acellular dermal matrix (ADM).Thirty-nine patients (78 breasts) who underwent hybrid breast reconstruction with an average follow-up period of 50.4 months (range, 27 to 73 months) were included in the study. Post-operative complications included hematoma [n = 2 (2.6 percent)], mastectomy skin necrosis [n = 12 (15.4 percent)], and fat necrosis [n = 6 (7.7%)]. There were no instances of implant infection, implant exposure, or flap failure. Polyglactin mesh and ADM were used in 24 breasts and 54 breasts, respectively. Implant malposition and capsular contracture occurred more frequently in the polyglactin cohort leading to 10 (41.7 percent) instances of re-operation for implant replacement compared to only 1 (1.9 percent) in the ADM cohort (p < 0.001). On multivariable regression analysis, polyglactin mesh was associated with a 36-fold greater probability of requiring implant replacement compared to ADM (p = 0.006).ADM (vs. polyglactin mesh) is associated with lower rates of capsular contracture and implant malposition in the context of hybrid breast reconstruction.
