Commentary on: Safety and Effectiveness of Single Session Mega Volume Fat Grafting for Breast Augmentation: A Space-Creating Concept and Clinical Experiences.

Abstract

See the Original Article here. In surgery, as in science, it is challenging to overturn what is held as common knowledge, more so when those principles in question pertain to the efficacy, viability, or especially safety of a technique so widely used and studied as fat grafting. In many ways that is what the Hsiao et al have sought to achieve.1 To answer the clinical question of repeat engraftment, with all the costs, risks, and inconvenience entailed, they have proposed certain technical modifications to fat preparation and delivery which they report allows for the safe, successful, and reproducible delivery of “mega volume grafts” of >300 mL per session (380-875 mL per breast across all patients). It is difficult to overstate the magnitude of the findings described, particularly as they substantially contrast the body of evidence developed over the last 15 to 20 years which has informed the common model of fat grafting as a careful balance between the metabolic needs of the graft and the ability of the recipient site to meet those needs.
