Abstract
Background: Gluteal fat transfer has witnessed a rapid increase in popularity, with fat transfer becoming an essential used tool in aesthetic surgery. Many studies detailed the technique of the procedure, while few explored the amount of fat needed for optimum results. This study aims to investigate the volume of fat that needs to be injected into the buttock, about 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 was 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 5.24ml/cm2 (2.91-7.88ml/cm2). Mean postoperative gluteal projection (immediately: 19.72cm, at 1-month: 20.90cm, at 2 months: 20.22 cm), was significantly higher than the mean preoperative projection (16.92cm). The area of injection was significantly higher in cases with ptosis (187cm2), than in cases without ptosis (158.67cm2). Conclusions: There was a significant improvement in postoperative projection immediately, at 1 and 2 months, with theThe highest projection was achieved at 1-month postoperatively. TheThe mean volume of injection per unit area within the study was 5.24ml/cm2.
