Endoscopic Intramuscular Fat Grafting for Precise and Safe Abdominal Contouring: Introducing the Supercharged Body Technique—Preliminary Report of a Novel Approach

Abstract Background High-definition (HD) liposuction is widely favored by plastic surgeons and patients for its capacity to create athletic, sculpted body contours. However, traditional HD liposuction may not effectively enhance muscle volume, resulting in a less natural appearance during motion. Objectives To evaluate the benefits and efficacy of the Supercharged Body Contouring (S-Bc) technique, which employs endoscopic intramuscular fat grafting to augment the rectus abdominis and external oblique muscles under direct endoscopic visualization. Methods From October 2019 and November 2024, 32 patients (30 male, 2 female) underwent abdominal deep plane liposuction with preservation of superficial fat, combined with the S-Bc technique, a novel endoscopic intramuscular fat grafting method designed to enhance abdominal muscle definition. Results No significant complications, such as infections, pulmonary embolism, venous embolism, or fat embolism, were reported. A minor complication, mild seroma, occurred in 8 patients. Other minor issues included temporary bruising in 2 patients and slight asymmetry in one, which was addressed with a secondary fat injection at 3 months. At the 1-year follow-up, the median patient satisfaction score was 9.5 out of 10 (range: 7-10, 95% CI: 9-10). The fat injection technique for enhancing muscle appearance produced sustained results in all patients. Skin tightening evaluations showed 56.25% (n = 18) of patients rated as good, 40.6% (n = 13) as very good, and 3.12% (n = 1) as moderate. Conclusions The S-Bc technique offers a safe and reproducible method for enhancing HD liposuction, achieving natural and dynamic abdominal contours. This case series suggests its applicability in aesthetic abdominal surgery, pending further validation in larger studies. Level of Evidence: 4 (Therapeutic)
