Hyaluronic High Definition Fill Technique.

[INTRODUCTION] Achieving a defined abdomen through traditional surgical methods like liposuction and abdominoplasty involves risks and significant downtime. Hyaluronic acid (HA) body filling has emerged as a minimally invasive alternative, offering immediate results with reduced recovery periods.

[PATIENTS AND METHODS] The high-definition abdomen through HA technique (HHD) was implemented on young men with BMI < 24.9, excluding those with obesity or excessive skin laxity. HA gel with large particle sizes (800-1800 μm) and high G prime was chosen based on subcutaneous thickness. Injections were guided by ultrasound into the lamellar fat layer between Camper's fascia and Scarpa's fascia, targeting abdominal metameres for enhancement. Participants completed the Global Aesthetic Improvement Scale.

[RESULTS] The technique produced satisfactory outcomes, enhancing abdominal metamere definition. Mild post-procedural hematomas and transient discomfort were noted. At 10 months, 71.4% of patients reported "much improved," and 28.6% reported "improved," per the GAIS questionnaire.

[DISCUSSION] Customizing HA characteristics and employing ultrasound guidance ensured safe and precise injections, minimizing vascular risks. Limitations such as HA's temporary nature and exclusions for surgical candidates were acknowledged.

[CONCLUSION] HHD using large particle HA proved effective in achieving aesthetic abdominal enhancements with minimal risks and downtime. This technique not only provided immediate results but also contributed to enhanced patient satisfaction and self-esteem. Further research is needed to explore broader applications and refine outcomes across diverse patient groups.
