BACKGROUND: Pre-pectoral implant breast reconstruction (IBR) is gaining popularity. Several techniques using different types of meshes and methods of placement have been described, but no method is currently considered standard. The aim of this study was to evaluate the outcomes of pre-pectoral IBR using acellular dermal matrix (ADM) for anterior implant cover. METHODS: Retrospective cohort study of consecutive patients who underwent pre-pectoral IBR between November 2016 to August 2018. Data on demographics, adjuvant therapies and operative technique was collected. Postoperative complications, length of hospital stay and secondary cosmetic procedures were recorded. Statistical analysis was performed using descriptive statistics, non-parametric tests and logistic regression. RESULTS: One hundred and eleven pre-pectoral IBR were performed in 65 patients. Median age was 41 [interquartile range (IQR), 35-51.5] years, and BMI 22 (IQR, 20.4-24.4) kg/m2. Therapeutic mastectomy was performed in 33 procedures with nipples preservation in 78 cases. The median mastectomy weight and implant volume was 360 (IQR, 220-533) gr, and 445 (IQR, 400-475) cc respectively. At a median follow-up of 18 (IQR, 12-22.5) months, 37 mastectomies had at least 1 complication, but only 12 required surgery. The implant loss rate was 4.5% (5 cases). Lipofilling as secondary procedure was performed in 10.8% of cases. Factors associated with post-operative complications on univariate analysis were nipple preservation (P=0.028), BMI (P=0.01) and implant volume (P=0.027) but these did not remain significant on multivariate analysis. CONCLUSIONS: Pre-pectoral IBR using ADM for anterior implant cover is associated with low complication and reconstructive failure rate. Patient selection and meticulous surgical technique are important for successful outcome. 2021 Gland Surgery. All rights reserved.
