In clinical practice, male breast disease with abnormal development and enlargement of breast tissue is known as gynecomastia, also known as male gynecomastia or gynecomastia. Due to the change of people’s dietary structure and the improvement of quality of life in recent years, the incidence of gynecomastia has been increasing year by year, and it accounts for about 60% to 80% of male breast diseases. Gynecomastia causes abnormalities in the appearance of the breasts, which not only affects the patient’s daily life and social life, but also leads to a certain degree of psychological disorder. Patients with moderate or severe cases are very eager to seek surgical treatment. Past experience has proven that drugs and fitness cannot fundamentally eliminate the appearance of gynecomastia, and surgical excision is the only treatment. Many patients are not very clear about the current popular surgical methods in China and only stay with a half-understanding. Here is a brief introduction for you: The traditional semi-annular incision at the areola margin will leave annular incision marks, and men in many cases will be topless, public bathing, facing intimate partners, so that the other party may not care, but for post-operative men, the areola incision marks may still cause some embarrassment in the heart. Breast lumpectomy is a modern minimally invasive surgical technique for the treatment of benign and malignant breast diseases. Breast lumpectomy involves making three to four 1-2 cm incisions in the patient’s lateral chest wall, with each incision inserting a duct-like working channel called a trocar. All subsequent operations are performed through these tubes, and the same steps as in open surgery are performed with extra-long surgical instruments under television surveillance to achieve the same surgical results. Although there is no surgical incision scar on the front of the breast, which reduces the surgical scar compared to the traditional large chest incision, it leaves three incision scars on each side of the chest wall, which can be embarrassing when the patient is bare-chested, and is not a scarless technique. EnCor allows for complete removal of breast lesions under minimally invasive conditions. EnCor is currently the most ideal minimally invasive sampling method for pathological biopsy to confirm breast lesions, especially those that are clinically inaccessible. Compared to traditional open surgery for breast masses, EnCor seems to be minimally invasive, but we must be clear that EnCor cannot do liposuction of the fat of the lateral breast wall and the parametrial area. The Anco rotary cutting system was originally designed as a biopsy instrument for breast fibroids and other small breast masses, only to obtain a small amount of tissue for pathological examination, which is the fundamental reason why most tertiary hospitals do not use it for male mastopathy surgery! We have summarized a set of our own techniques based on nearly two decades of clinical experience in surgery through research and thousands of surgical practices. According to the type of breast tissue enlargement of the patient, different surgical methods are decided, such as fat aspiration, fat aspiration combined with glandular excision, and simple glandular excision. In the case of male breast development breast removal, the incision is made in the areola with a minimally invasive incision of less than three millimeters (combined with our own Song’s super reduction fine suturing, we can achieve a scarless post-operative effect), and no incision is left on the lateral chest wall or breast, thus avoiding leaving embarrassing incision scars in the breast area and lateral chest wall. Minimally invasive incision of the areola removes the breast tissue and preserves the blood supply to the nipple and areola to the greatest extent possible, thus avoiding the possibility of ischemic necrosis of the areola nipple; at the same time, minimally invasive incision of the areola does not change the original tension of the areola skin and can completely ensure that the areola remains in the normal position of the breast after surgery.
