Effect of Reduction Mammoplasty on Pulmonary Function Tests

Abstract

In patients with breast hypertrophy, excessive breast weight applies pressure on the thorax, which may disrupt the normal breathing. The purpose of this study is to evaluate the impact of the breast hypertrophy and reduction mammoplasty on respiratory function. A comprehensive search of 3 databases, PubMed, Ovid, and Scopus databases, was performed. “Mammoplasty” and “respiration or pulmonary function tests” were the keywords used to search for relevant articles. Ten studies involving 280 patients with breast hypertrophy were included in the final review. Seven articles demonstrated an increase in at least 1 pulmonary function test value after the surgery. This systematic review revealed that, preoperatively, pulmonary function test values of the patients are usually in the normal range. Nonetheless, reduction mammoplasty still improves lung function parameters. Additionally, patients with respiratory complaints felt improvement in their symptoms after the surgery. However, future studies are needed, as heterogeneity among studies was observed.
