If the areola is too large and the breast is not large or has no sagging, a simple partial excision of the areola skin can be performed to reduce the size of the areola. The surgical method is: centering on the nipple, draw a circle with an appropriate radius (usually 1.5-2.5cm). The circumferential areolar skin outside this range should be removed, and the dermis and subcutaneous vascular network should be preserved to prevent insufficient blood supply to the nipple and areola. A triangular piece of skin is removed from the outer skin on both the inner and outer sides in the transverse direction to reduce the radius and make it consistent with the radius of the new areola. Finally, the outer ring is slightly freed subcutaneously and then sutured in position. Women's areolas will become colored and enlarged after pregnancy, so there is generally no need for areola enlargement surgery for girls.
