Patient satisfaction and outcomes following reduction mammoplasty is important to measure, being a being a reconstructive procedure with physical and cosmetic benefits. This study aimed to evaluate patient satisfaction and the various questionnaires that have been devised for this measurement. A systematic search of literature was performed in PubMed, Cochrane Library, Medline and Scopus databases from 1966 to July 2018 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. After application of pre-determined inclusion criteria by two authors, 95 articles were included. Data was extracted from included studies relating to demographics, surgical technique, questionnaires used and physical, psychological and aesthetic outcomes. Of the 95 studies included (9,716 patients), 58 studies (5,867 patients) reported on overall satisfaction with a mean rate of 90.26%. Researchers' own nonvalidated questionnaire was most commonly used in 52.6% of studies. Validated questionnaires used were most commonly the SF-36 (25.3%), Rosenberg self-esteem scale (RSES) (9.5%) and BREAST-Q (8.4%). All showed improvement in physical and mental health. Our findings suggest that women who have undergone reduction mammoplasty for breast hypertrophy report postoperative satisfaction and improvement in quality of life. Of the validated questionnaires used, a combination of those assessing both mental, physical and psychosocial health as well as breast-specific surveys were most commonly used and may provide an accurate assessment of patient outcomes.
