Background: With the increased use of acellular dermal matrices (ADMs) in implant-based breast reconstructions (IBBRs), the evaluation of patient-reported outcomes becomes more important. Methods: Patients who underwent an immediate human ADM-assisted, submuscular IBBR were included in this noninterventional, multicenter, prospective cohort study. Patients with primary reconstruction (cohort A) and patients with a revision surgery after capsular fibrosis (cohort B) were followed up for 12 months after surgery. Quality of life (EORTC BR-23) and patient and surgeon satisfaction scores (1 [“very satisfied”] to 6 [“not satisfied”]) with the outcome and the aesthetic result evaluated by 2 independent, external experts were assessed. Results: Eighty-four patients were enrolled in the study. The mean patient satisfaction score was 2.1 ± 0.8, with higher satisfaction in cohort B (p = 0.041). The score did not change significantly during the follow-up (p = 0.479). The mean satisfaction score of the surgeons was 2.0 ± 0.7; it was also higher in cohort B (p = 0.016) and showed no changes over time (p = 0.473). The mean aesthetic result was 2.2 ± 0.7. 92.9% of the patients completed at least 1 quality of life questionnaire. Body image and sexual functioning increased during follow-up. One year after surgery, the mean scores were 77.2 ± 22.5 and 44.7 ± 27.3, respectively. Conclusion: The level of satisfaction among patients and surgeons and the score of the aesthetic result were constantly high among patients after ADM-assisted IBBR. Higher satisfaction scores could be observed after revision surgery caused by capsular fibrosis (cohort B) compared to primary reconstruction (cohort A). Quality of life increased during the first year after surgery.
