Unilateral Reduction Mammaplasty

Abstract

Various traditional mammaplasty techniques have been suggested for unilateral breast reduction, and an inverted-T incision is still the most popular approach. However, unilaterally performed traditional techniques can rarely provide long-lasting symmetry because the operated and the unoperated breasts react differently to aging, weight changes, and pregnancy. Considerable residual scarring, interference with clinical and mammographic evaluation, and limited versatility are all major drawbacks of traditional procedures. We have performed unilateral mammaplasties on 47 patients with various types of congenital and acquired asymmetries, reducing and sculpturing the breast from the undersurface by means of minimal incisions, always avoiding horizontal scarring in the inframammary crease. Through a vertical infra-areolar incision, the breast is completely detached from the underlying pectoralis fascia and hooked up, thus completely exposing the undersurface of the mammary cone. The breast can thereafter be reshaped according to the size and shape of the contralateral breast by means of a discoid resection and/or selective sectoral removal of excessive subcutaneous tissues; modifications of the basic discoid resection can increase anterior projection of the new breast mound and can change the inclination of the anteroposterior breast axis on the anterior chest wall both on the horizontal and vertical planes. The results show that if criteria for patient selection are carefully respected, the procedure can provide long-lasting symmetry with minimal residual scarring and fully preserve the breast anatomy, function, and vascularization.
