Gluteal Shape Framework for Augmentation Surgery: A Systematic Review of the Literature and Proposed Classification System

Background:Gluteal augmentation is used to improve the size and shape of the buttocks. Unlike other anatomical areas, such as the breasts, where there are classification systems for size and projection, no standardized methods for classifying gluteal size and shape exist. Patients seeking augmentation rely on photographs to communicate their desired result to surgeons. The authors' study objectively reviews this topic and proposes a novel classification system for the buttocks that can provide an organized framework for patients and providers. Methods:A systematic of the literature was conducted on March 17, 2021, using various combinations of the following terms: "gluteal augmentation," "classification," "size," "gluteoplasty," and "Brazilian butt lift." All eligible articles were included for analysis. Results:The PubMed/MEDLINE searches yielded 49 articles and abstracts. After review, eight publications were chosen for analysis. All publications were found in plastic surgery journals, with the most common journals as follows: Aesthetic Surgery Journal (n = 4), Clinics in Plastic Surgery (n = 2), Annals of Plastic Surgery (n = 1), and Plastic and Reconstructive Surgery (n = 1). There are no articles in the plastic surgery literature that provide a standardized classification system for gluteal size determination. Conclusions:The authors' study revealed the need for a standardized classification system for gluteal size and shape. Although the publications analyzed discussed various techniques for related procedures and provided ways to improve aesthetic outcomes, none presented a system for reproducibly classifying size and shape. By introducing a classification system, we hope to enable plastic surgeons to more accurately and efficiently discuss their patient's goals.
