Mastoplasty for: mastopexy, reduction and reconstruction are established procedures, but there are still uncertainties regarding their planning and execution, due to the large number of techniques that make it difficult for the young surgeon and sometimes for the already experienced ones, to decide which is the best to perform .To contribute to this theme and make surgical decision-making objective, the present research was designed to verify the accuracy by establishing the margin of error or success and the agreement between the methods found by the comparative statistical analyzes of the established results called "Volumes Desired Breasts” and “Final Breast Volumes”, thus validating the use of the Pythagorean Theorem and the Expression for Cone Volume Calculation in the preoperative period as predictive and the surgical method as universal. The surgical steps were created with the analogy made between the topographical and descriptive anatomy of the breast with the geometry of solid bodies in which the breast without ptosis was considered a straight cone and the ptosis an oblique cone, which makes it possible to use the theorem and the expression and creation of the operative technique. The type of research, longitudinal, prospective, selfcontrolled and analytical, was carried out in 31 patients, operated in the years 2017 to 2021 at the Plastic Surgery and Reconstructive Microsurgery Service of the University Hospital. from the Federal University of Ceará. Three protocols were created for the method: clinical examination, in which the mentioned theorem and expression were used; surgical procedure, which used the description and the descriptive and topographic human anatomy of the breast with the Archimedes test and the statistical analysis, establishing the confidence interval, relative deviation, logistic regression and agreement test to verify the accuracy. The results of the analyzes indicated 98% satisfaction with the surgical procedure, the statistics showed a margin of error of 7.9%, that is, 46.47% of what was predicted, which was 17% (100%), a four times greater probability of patient was satisfied than dissatisfied and a concordance between the methods with coefficient values “3.39” and intraclass correlation “0.976” very small, considering the established parameters. The 05 most used operative techniques with the proposed method and their sociodemographic results were discussed, analyzed and compared, in addition to the various objective aspects arising from the use of the theorem and expression cited as the foundations of the technique created. The accuracy was verified with a large margin of safety, validating the expression and the Universal Method for Mastoplasty
