The effects of breast reduction on pulmonary functions: A systematic review.

Breast reduction is one of the most commonly requested and performed plastic surgery procedures, and its psychological, esthetic, and analgesic benefits are well known. Several studies dealing with the effects of reduction mammoplasty on the physiology of respiration have been published in the past decades. This systematic review aims to assess whether bilateral breast reduction is associated with measurable improvement in lung function in women with macromastia. This review was performed in accordance with the PRISMA guidelines. PubMed, SCOPUS, and Web of Science databases were queried in search of clinical studies that investigated lung function in women undergoing breast reduction for macromastia and reported any type of parameter or outcome measure relevant to pulmonary function. The search yielded 394 articles of which 15 articles met our specific inclusion criteria. The primary outcome measures of the studies and their respective results were tabulated, contrasted, and compared. The 15 studies included in this review cover the period from 1974 to 2018. According to most included studies, reduction mammaplasty produces a change of objective respiratory parameters, such as spirometric tests or arterial blood gas (ABG) measurements; nevertheless, the clinical and functional relevance of the observed changes is debatable.
