Optimizing the results of gluteal fat transfer – An attempt to identify the volume of fat injected to reach an appealing projection.Abstract Background: Gluteal fat transfer has witnessed a rapid increase in popularity, with fat transfer becoming an essentially used tool in aesthetic surgery. Many studies detailed the technique of the procedure while few explored the amount of fat needed for optimum results.The aim of this study is to investigate the volume of fat that needs to be injected into the buttock, in relation to the total surface area injected, and if that would be affected by the presence of preoperative gluteal ptosis.Methods: This study included 20 female patients seeking glutleoplasty by fat transfer. Patients were assessed preoperatively, and preoperative gluteal projection was recorded. They underwent gluteal augmentation using autologous fat transfer. Postoperatively they were assessed, and postoperative gluteal projection recorded immediately, at 1-month, and 2-months. The volume of fat injected per centimeter was calculated.Results: The mean volume of injection per unit area within the study was 5.24 ml/cm2 (2.91 – 7.88 ml/cm2). Mean postoperative gluteal projection (immediately: 19.72 cm, at 1-month: 20.90 cm, at 2-months: 20.22 cm), was significantly higher than the mean preoperative projection (16.92 cm). The area of injection was significantly higher in cases with ptosis (187cm2), than cases without ptosis (158.67 cm2). Conclusions: There was significant improvement in postoperative projection immediately, at 1 and 2 months, with the highest projection achieved at 1-month postoperatively. The mean volume of injection per unit area within the study was 5.24 ml/cm2.
