External and internal oblique muscle amplification by Semilunaris PArallel to Rectus fat Transfer (SPARTAN)

High-definition body sculpting has revolutionised body contouring surgery worldwide. Intramuscular fat grafting for cosmetic purposes has been utilised for many years to enhance the underlying muscular anatomy. The purpose of this study is to present a novel technique of muscular fat grafting to the oblique muscles aimed at enhancing the outcomes of high-definition body contouring surgeries. This technique is referred to as the Semilunaris Parallel to Rectus Fat Transfer technique (SPARTAN).

This method of oblique muscle amplification can be executed under direct vision during an abdominoplasty or under ultrasound (US) guidance in patients undergoing liposuction alone. The objective is to infiltrate fat tissue into the oblique muscles, thereby enhancing the athletic appearance of the abdominal region.

The SPARTAN technique was applied to 51 patients, with no complications observed. This procedure complemented the Rectus Abdominis Fat Transfer (RAFT) and Ultrasound-guided Rectus Abdominis Fat Transfer (Ug-RAFT) techniques.

The SPARTAN technique serves as an adjunct to muscle enhancement, achieving a more defined and athletic look in high-definition body contouring. It can be performed under direct vision or with US assistance.

Level of Evidence: Level IV, therapeutic study.
