Concentric mastopexy presents many challenges to the plastic surgeon, especially when breast augmentation is part of the treatment plan. Radial plication is a reproducible and accurate technique for elevating the nipple-areolar complex and shaping the breast mound. Patient selection is important to the success of the radial plication procedure and concentric mastopexy in general. Although most surgeons agree that patients with smaller degrees of nipple ptosis and smaller breasts have better results than patients with greater degrees of nipple ptosis and larger breasts, there has never been an algorithm for patient selection. Regnault's classification of breast ptosis addresses the degree of nipple ptosis, but no consideration is given to breast volume. Radial placation proved to be a valuable tool in the treatment of 87 patients undergoing concentric mastopexy in the author's practice over the past 30 months. An algorithm addressing degrees of breast ptosis and breast volume is provided. The plastic surgeon can anticipate gratifying results if the algorithm provided is incorporated into his or her patient selection for concentric mastopexy. The concentric mastopexy technique is similar to the tailor tack procedure for standard mastopexy, allowing the plastic surgeon to mold and shape the breast before making a critical incision.
