Implant-Based Breast Reconstruction: Impact of Body Mass Index on Postoperative Complications and Aesthetic Results: A 5-Year, Single-Center Study

Abstract Background Increasing adoption of implant-based breast reconstruction (IBR) has raised expectations regarding postoperative outcomes and aesthetic results. BMI has been extensively explored as a predictor of complications. This study is the first to examine complication rates in underweight subjects, and compares these rates among underweight, normal weight, overweight, and obese patients. Objectives The aim of this study was to investigate the influence of BMI on postoperative complications and aesthetic results in IBR following mastectomy. Methods Retrospective analysis encompassed patients undergoing mastectomy with subsequent IBR, performed by a collaborative team of breast and plastic surgeons. Demographics, treatment specifics, and outcomes were evaluated by univariate and multivariate regression models. Significance was determined at P < .05. Results In total, 1046 IBRs were performed in 921 patients, of whom 63 had a BMI
