About Unilateral Gynecomastia

Breast #asymmetry is the condition when both breasts are not equal in size. In men, gynecomastia can include only one or both breasts. #Unilateral gynecomastia occurs when only one breast is larger due to gynecomastia, while the other breast is typically normal in both size and shape. #Bilateral asymmetry occurs when gynecomastia is present in both breasts, although each to a different degree. The amount of glandular tissue can affect the size, shape, and location on the chest wall of the enlarged area, the size of the areolas, and protrusion and diameter of the nipples.

Unequal or #unilateral gynecomastia is not an uncommon condition. It is more significant when there are very noticeable differences between the two breasts. Usually, the degree of difference between the two breasts is not severe. Through a study of his patients, however, more than 80% of male breasts are not symmetrical, but the severity varies greatly from patient to patient. Patients should take this into consideration while examining their chests prior to surgery.

In addition to correcting the  difference between breast sizes, the #areola often shrinks when #gynecomastia excision is performed. In more pronounced cases, the areola may even be larger. When the glandular tissue is removed, the areola #symmetry may improve.
The conditions that make up #asymmetry can often be corrected to some degree. It is very individual and varies for each patient. Every prospective surgical candidate should discuss this condition with an experienced plastic surgeon prior to surgery. The plastic surgeon’s role is to educate each individual patient as to the possible degree of improvement that can be realistically achieved in his particular case.

Asymmetric gynecomastia

Asymmetric gynecomastia is common.

How should I choose a surgeon? First,Must be a board certified Plastic surgeon(Not a cosmetic surgeon)
Choose carefully. The decision is yours. Advice to assist in making your selection.
1. Experience matters. Choosing a surgeon increases the likelihood that they have seen a case similar to yours in the past. Selecting a surgeon whose practice is focused on gynecomastia exclusively is also an indicator of experience.
2. Results matter. The more before-and-after pictures, the better. Pay attention whether the surgeon is confident enough to show multiple angles of the same patient.
3.Only gynecomastia Reviews matter.
4. Expertise matters. Is your surgeon recognized by the profession as an authority in the field? Have they authored books or medical journal articles regarding your surgery?
Be realistic about your expectations. Also, revision surgery tends to be significantly more difficult than initial surgery.

Thank you for the question. Accurate diagnosis would necessitate physical examination. It IS important to differentiate gynecomastia ( excess breast tissue) from lipomastia ( otherwise known as pseudo-gynecomastia or excess adipose tissue of chest wall). Treatment will differ depending on diagnosis. My best suggestion: seek consultation with board-certified plastic surgeons who can demonstrate significant experience achieving the types of outcomes you will be pleased with. You may find the attached link helpful to you as you learn more. Best wishes.
