Recently, our burn plastic medicine and aesthetic surgery department has applied the innovative combination of minimally invasive suction and incision method to treat gynecomastia in many cases and achieved satisfactory surgical results. The whole procedure is less bleeding, safe, minimally invasive, painless, quick recovery, no obvious surgical incisions, less follow-up treatment cost, cost-effective and other advantages, which has achieved good social benefits. Minimally invasive aspiration and excision treatment for gynecomastia is one of the many cosmetic surgical procedures that have been improved by the Burn Plastic Medicine and Aesthetic Surgery Department under the premise of “safety and effectiveness, minimally invasive quality”, and the core of this procedure is a special method of incision away from the breast area, which is popular among patients because of the reduction of surgical scars. A micro-incision of about 3 mm is made and the suction knife is “extended” to the hypertrophy through a “subcutaneous tunnel”, the lesion is identified, the blade is attached to the lesion, and the hypertrophy is cut layer by layer and sucked out of the body by positive pressure suction. The operation also preserves the original anatomical structure and physiological function of the normal male pectoral tendon, and the anatomical level of the operation is clear and does not affect the function of the pectoral muscle. Gynecomastia (also known as male gynecomastia, or Gynecomastia in English) is a common male breast lesion with the symptom of abnormal male breast development. This condition often occurs in adolescent males and is mainly due to a hormonal imbalance in the body during puberty, which usually disappears on its own. It is rare to see this symptom in adult men. However, in some special cases, such as; lesions, hormone medication, etc., the hormones in the male body become imbalanced and secrete estrogen, or due to the appearance of tumors, gynecomastia also occurs in adult men. Although this disease is not common clinically, it causes great psychological pressure to patients and affects their normal life, and there is also the possibility of cancer, so timely, accurate and effective diagnosis and treatment of this disease should not be taken lightly. Therefore, timely, accurate and effective diagnosis and treatment of this disease should not be taken lightly. Early detection and early treatment are essential.
