The author presents a reduction mammoplasty technique in which an infra-areolar longitudinal incision is used. The incision can be either one line, without skin removal, or an ellipse, with some skin to be removed. The gland is totally freed from the pectoral muscle and the resection of the mammary cone's base is then done, using pre-established measurements. The skin retracts spontaneously over the remaining breast tissue, which maintains its original shape in a smaller size.
