Abstract
BACKGROUND
There is a paucity of evidence comparing the safety of prepectoral and partial subpectoral implant-based breast reconstruction using acellular dermal matrices (ADM). We performed a meta-analysis to evaluate the postoperative complications of the two approaches.
METHODS
PubMed, EMBASE, Web of Science and Cochrane Library were searched to retrieve relevant articles. The rates of the complications were, respectively, pooled, and relative risk (RR) was estimated with 95% confidence intervals (CIs) to compare the incidence between the two cohorts.
RESULTS
Ten articles reporting on 2667 breast reconstructions were eligible. The hematoma rate was lower in the prepectoral group (RR = 0.590, 95% CI 0.351-0.992). No significant difference was observed in terms of seroma (RR = 1.079, 95% CI 0.489-2.381), skin flap necrosis (RR = 0.936, 95% CI 0.587-1.493), infection (RR = 0.985, 95% CI 0.706-1.375), tissue expander/implant explantation (RR = 0.741, 95% CI 0.506-1.085), wound dehiscence (RR = 1.272, 95% CI 0.605-2.673), capsular contracture (RR = 0.939, 95% CI 0.678-1.300) and rippling (RR = 2.485, 95% CI 0.986-6.261). The RR of animation deformity for the prepectoral group compared with the subpectoral group was 0.040 (95% CI, 0.002-0.853).
CONCLUSIONS
This systematic review suggested that with appropriate patient selection, prepectoral breast reconstruction could avoid animation deformity without incurring higher risk of early wound complications, capsular contracture or rippling than partial subpectoral breast reconstruction. Plastic surgeons should complete a comprehensive assessment of the patients before choosing appropriate surgical approaches in clinical practice.
