Accurate Plane Fat Grafting in Gluteal Augmentation: An Anatomic Study.

The safety of gluteal fat grafting is a global concern in plastic surgery. To test whether fat grafting to the buttocks with Auto Stop Reach (ASR) technology prevents penetration from the subcutaneous space into the fascia and muscle layers of the buttocks. Fat transfer simulation was performed with blue dye on 8 fresh tissue cadaver buttocks by 3 board certified plastic surgeons (SSK, SC, BW). An open control was used to visualize the process in the different anatomic layers while all of the other procedures were performed blindly akin to live surgery. After blue dye transfer reached maximum capacity (ranging from 400-800cc per buttock), dissection of the anatomical layers of the buttocks was performed to determine the plane(s) of injection. Blue dye fat transfer injection to the buttocks did not penetrate the gluteal fascia or muscle layers from the subcutaneous space while using ASR. Auto Stop Reach Technology supports the safety of gluteal fat transfer in the subcutaneous space by board-certified plastic surgeons.
