Despite the significant evolution of mammaplasty techniques, some undesirable changes on the operated breasts result in evident dissatisfaction for both patients and doctors. The main reason is that the breast has a tendency to resume its previous shape months after the operation. In pursuit of a procedure that would avoid this untoward morphologic evolution, we set to work on the development of a new approach of broad fixation to maintain the breast shape and to avoid ptosis by using the inferior third of the pectoralis major muscle. The authors report their experience with 46 consecutive cases of breast reduction and mastopexy operated between March 1994 and November 1995, studying the surgical procedure employed, its advantages, limitations, and possible complications.
