However, the impact on cost and number of additional procedures is not well described. METHODS Patients with unilateral free flap reconstruction were identified in national administrative data from 2017-2021 and followed for one year. Patients were stratified by immediate and delayed reconstruction, then further stratified into groups with simultaneous symmetrizing surgery and without simultaneous symmetrizing surgery. Thirty-day complications included transfusion, wound dehiscence, surgical site infection, hematoma/seroma and thromboembolism. Costs of initial hospitalization and subsequent surgeries were determined. Deferred symmetrizing surgeries within one year were identified. Chi-squared and Fisher exact tests, and Wilcoxon tests were used for statistical analysis. RESULTS A total of 1136 patients were identified. 638 were delayed reconstructions: 75 with simultaneous symmetrizing surgery and 563 without. There were no significant differences in patient characteristics or 30-day complications. Within one year of index reconstruction, fewer patients with simultaneous symmetrizing surgery underwent a revision surgery (29% vs 51%, (p=0.001)) or at least one additional procedure (36% vs 57%, p<0.001). Patients with simultaneous symmetrizing surgery had lower total costs ($35,897 vs $50,521, p=0.005). There were 498 immediate reconstructions: 63 with simultaneous symmetrizing surgery and 435 without.
