The aim of this study was to compare long-term clinical and patient-reported outcomes in terms of satisfaction and health-related quality of life (HRQoL) following postmastectomy breast reconstruction using BREAST-Q in patients undergoing implant-based reconstruction, abdominal-based autologous reconstruction, and combined reconstruction (with implant and LD flap or implant and TDAP flap). A cross-sectional study was conducted. Patients had undergone delayed postmastectomy breast reconstruction and completed the BREAST-Q reconstruction module. The results were related to the clinical data obtained from the clinic’s patient record system. A 5-year examination was included. Mean scores and standard deviations were calculated. Kruskal–Wallis test, Chi-square goodness of fit test and Chi-square test were used for the statistical analysis. Overall, 110 patients (n = 24 implant, n = 38 autologous, n = 48 combination) were included. Patients with autologous reconstruction reported greater postoperative satisfaction with breasts (p
