The Impact of Reduction Mammaplasty on Breast Sensation: A Systematic Review.

Loss of sensation is one of the most feared complications of breast reduction surgery. Although several techniques have been proposed to maximize sensitivity preservation, the scientific literature still reports contradictory findings. This systematic review aimed to assess whether breast reduction mammaplasty is associated with measurable changes in breast sensation. This review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed (National Institutes of Health, Bethesda, MD), Scopus (Elsevier, Amsterdam, the Netherlands), and Web of Science (Clarivate, Philadelphia, PA) databases were searched for clinical studies investigating breast sensation after breast reduction mammaplasty. The initial search identified 1523 studies of which 22 articles met our specific inclusion criteria. Most of the included studies are consistent in describing only transient sensation decrease or even sensation improvement after surgery compared to the presurgery condition with any approach, except those investigating outcomes after superior or superolateral pedicle reduction mammaplasty. Nevertheless, the overall quality of evidence is low or very low due to the limited availability of randomized controlled trials or controlled studies and the high risk of bias.
