Anisomastia is the visible difference in size, shape or position of the breasts. It is more common among women. It can be congenital or due to various illnesses or surgeries such as removal of breast tumors.

“Small differences in size, shape or position of the breasts is normal and occurs in many women. However, when differences are large and cause aesthetic problems, they can be treated with plastic surgery.” as Dr. Ioannis Dalianoudis explains.

The Procedure


The surgery to correct anisomastia may include an increase of the smaller breast with a silicone implant placement, the decrease of the larger one, or both procedures simultaneously. Depending on the nature and causes of anisomastia the surgeon will choose the appropriate intervention for correction. The postoperative course is similar to other breast surgery procedures.

It is performed under general anesthesia and the patient needs to stay in the clinic for one night as a precaution.

Depending on the type and causes of anisomastia, the surgeon, after a complete clinical examination will choose the appropriate personalized operation to correct the anisomastia.

Postoperative Course


Immediately after the operation, a pressure bandage is placed, which is removed one day later, where a special bra is placed. The special bra must remain for a period of one month.



Are there any complications occurred from Anisomastia Surgery?

Complications are not common and are limited by the application of the appropriate technique by a qualified and experienced medical team. Preventive antibiotic treatment is necessary, as well as the patient’s adherence to postoperative instructions.

At what age can the correction of anisomastia be performed?

Ideally, the operation should be performed after the patient has reached adulthood, so that the normal development of the breasts has been completed.

When can I return to my daily activities and work?

As long as it is not a job that requires intense physical activity, then the patient can return to work after a few days.

When can I exercise?

It is recommended that you avoid intense exercise for the first month, as well as lifting weights or moving your arms vigorously.
