Liposuction alone can effectively treat Grade I Webster/Simon gynecomastia cases. The procedure involves making small incisions, infiltrating a numbing solution, and using a thin cannula to suction excess fat. It is suitable for patients with good skin elasticity and minimal glandular enlargement. Additional techniques like glandular tissue excision or skin tightening may be needed for optimal results in cases of significant enlargement or excess skin. Advanced techniques like power-assisted liposuction (PAL) and ultrasound-assisted liposuction (UAL) have improved outcomes. UAL, including Vibration amplification of sound energy at resonance (VASER), is particularly effective for treating fibrous glandular tissue while ensuring skin contraction and minimizing risks.
