In past decades, several invasive and noninvasive aesthetic procedures have been sought as a way to improve body contouring, and one may resort to uncertified and potentially dangerous procedures to achieve that goal. An example of this practice would be the resection of ribs to reduce the waist for aesthetic reasons. The objective was to check scientific evidence on the effectiveness and safety of removal of floating ribs for aesthetic purposes. A systematic review of the literature was carried out in EMBASE/Elsevier, Cochrane, Scopus, Medline, PubMed, BVS, SciELO, OneFile, and Lilacs, throughout the period until June 2020, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Fifty-six articles were found in all databases. After applying the inclusion criteria, by reading the title and abstract of the studies found, only two articles were definitively included. One addressed the possibility of removing the 7th and 8th ribs for improving body contouring in patients with an exaggerated anterior projection of the chest wall, without showing cases or surgical techniques. The other demonstrated procedures of body contouring in transgender by the removal of the 11th and 12th ribs in five of the 22 patients studied, just providing a brief description of the surgical technique used, without details. Despite the relevance of the theme and its popularity, there is not enough scientific evidence to support the practice, effectiveness and safety of the resection of ribs for aesthetic purposes. This journal requires that authors assign a level of evidence to each article.
