There are many kinds of congenital breast and chest wall irregularities that affect children, adolescents, and adults. While the majority can be corrected through surgery (whether one or multiple), many irregularities cannot be repaired until the patient is fully grown or developed, and this is the case for treating breast asymmetry. It is best to delay surgical intervention until the patient is between 17 and 18 years of age. While breast asymmetry does not create medical problems for the patient per se, the psychological effect can be quite significant – especially in adolescent females. They may feel personally embarrassed, socially isolated, and have difficulty in forming relationships if the breast asymmetry is left untreated. Breast asymmetry is not uncommon in females, but when it is more pronounced plastic surgery is an excellent way to create symmetry. A breast may be hypoplastic (deficiently developed) or absent altogether (aplasia), and both situations may be treated. When a patient has a hypoplastic breast, the plastic surgeon’s aim is to make the deficient breast match the other, fully developed breast. This can be done using breast augmentation, breast reduction, or both procedures. Breast augmentation would enhance the hypoplastic breast to be congruent with the other breast. Breast reduction (mastopexy) would reduce the size of the other breast to be congruent with the hypoplastic breast. However, plastic surgeons often use both techniques to achieve breast symmetry and aesthetic harmony.
