Introduction Breast-Q® instrument has been used for measuring the quality of life of patients undergoing breast reduction or breast lift surgery. The factors that determine the improvement in the quality of life of these patients are unknown. The aim of this work is to identify the determinant factors of improvement in the quality of life in patients undergoing breast reduction. Materials and methods A prospective cohort of 41 patients undergoing breast reduction or breast lift without implants was studied. Sociodemographic features, anthropometric measurements, variables related to surgery were studied and the Breast-Q® instrument was applied. For statistical analysis it was used descriptive statistics, generalized estimating equations models and linear and logistic regression models. Results We found improvement in the quality of life, globally (P < .0001) and per domains. Among the determining factors, there was a positive correlation between the extent of resection and improved quality of life globally (P = .032) and in the domain of physical symptoms (P = .012). Also highlights an improvement of 50% with resection of breast tissue above 300 g. Conclusion Breast reduction and breast lift surgery significantly increases the quality of life measured by the Breast-Q® instrument in patients with breast hypertrophy or ptosis. The determinant factors of this improvement would be directly related to the amount of tissue resected, with a 50% improvement with resections above 300 g.
