Internal Bra: A literature Review and Sub-Classification of Definitions.

Background: The term 'internal bra' refers to a range of techniques that aim to stabilise the position of the breast and improve longevity of surgical results. It is increasingly being used to describe techniques in surgical literature and on patient information platforms, including social media. However a lack of consistency in the use of the term is a potential source of confusion and conflicting information.
Objectives: This narrative review aims to improve understanding of what is meant by the term 'internal bra', by providing an overview of the different techniques it refers to and suggesting more specific terminology for use going forward.
Methods: A literature search of the Medline, Embase, and Google Scholar databases was conducted to identify papers in which a surgical technique was described using the term 'internal bra'.
Results: 'Internal bra' techniques can be categorised into 5 groups: mesh techniques, acellular dermal matrix techniques, suture techniques, dermal flap techniques, and muscle techniques. Promising results exist for techniques in each group; however, research is generally limited by small studies with short follow up periods, and significant inconsistencies exist in use of the term 'internal bra'.
Conclusions: The titles of the five groups identified in this paper should be used going forward when discussing 'internal bra' techniques, in order to bring greater clarity to both surgical literature and patient information. Further research is also required to establish if 'internal bra' techniques truly improve longevity of surgical results and if one technique, or group of techniques, is superior.
