Gynecomastia is a benign increase in male breast size resulting from hypertrophy or increased glandular parenchyma and the accumulation of subcutaneous fat tissue deposits. Gynaecomastia can occur due to excess fat or glandular tissue or as a combination of both types of tissue with excess skin. Gynaecomastia cannot be prevented but can be corrected by corrective interventions such as liposuction, reduction, or mastectomy with nipple-areola skin displacement. It is also important to note the need for an examination by endocrinologists to detect any hormonal causes of breast enlargement. The male breast reduction surgery is performed under general anesthesia and the procedure lasts for two to three hours, after which the patient is kept in the Polyclinic until the next morning for safety and monitoring. The incision is placed along the edge of the areola. Less complicated cases with only fatty tissue as the cause can be completely corrected by liposuction, which is also the first method of choice in treating gynecomastia. After the procedure, swelling usually lasts for 3 to 5 weeks, and a return to sporting activities and removal of elastic support is planned after 4 weeks.
