Accurate Plane Fat Grafting in Gluteal Augmentation: An Anatomic Study

Area of Science:

• Plastic Surgery
• Anatomical Studies
• Surgical Technology

Background:

• Gluteal fat grafting is a widely used cosmetic procedure.
• Concerns exist regarding the safety of fat transfer to the buttocks.
• Ensuring injection into the correct anatomical plane is crucial for patient safety.

Purpose of the Study:

• To evaluate the efficacy of Auto Stop Reach (ASR) technology in preventing deep tissue penetration during gluteal fat grafting.
• To determine if ASR technology can maintain fat injections within the subcutaneous space of the buttocks.
• To assess the safety implications of ASR technology in plastic surgery.

Main Methods:

• Simulated fat transfer using blue dye on 8 fresh cadaver buttocks.
• Procedures performed by 3 board-certified plastic surgeons.
• Open control for visualization and blind procedures mimicking live surgery.

Main Results:

• Fat injections using ASR technology did not penetrate the gluteal fascia or muscle layers.
• Blue dye remained confined to the subcutaneous space in all tested specimens.
• The technology demonstrated consistent performance across multiple procedures.

Conclusions:

• Auto Stop Reach (ASR) technology enhances the safety of gluteal fat transfer by ensuring injections remain in the subcutaneous space.
• ASR technology provides a reliable method to prevent inadvertent penetration into deeper anatomical structures.
• This technology supports safe practices for plastic surgeons performing buttock augmentation via fat grafting.
