The author recommends reducing scars after mammaplasties, using the L technique. Their use should be limited, based on resections of skin surplus to the extent of the ptosis. Lines and guides are described that point to any tactic and anatomically perfect breasts. The “aesthetic pathologies” are dealt with, the ptosis is quantified in centimeters, the surgical procedure of L is chosen, and its limitations are described. Hypertrophic and ptotic breasts are reduced and shaped as classified. The maneuvers involved in suturing the incisions in a “semicolon” shape are described, starting from the side of the inframammary crease to the medial side, then upward, ending in a vertical suture V–Y or “circular compensation areolar bag” as the skin surplus in the periareolar region, reducing the extent of the horizontal scar, which should be the maximum A–M measurement plus 2 cm. In ptosis of less than 7 cm, the results were of good quality, with no significant residual ptosis and no distortion of the areola and the cone obtained. The difficulties and advantages of the technique are shown.
