Mastopexy and reduction mammaplasty techniques have evolved with time, pursuing the aim of an effective and reliable technique that produces a well-shaped breast and reduces the amount of scarring. The authors believe that the L mammaplasty achieves the best results in terms of a short scar and a good, stable shape. They present their technique of a modified L mammaplasty with a resulting scar in the shape of a J, which implies a central breast resection with the nipple-areola complex transposed on a superior pedicle. The correct execution of the preoperative markings and the shaping of the gland tissue are mandatory to obtaining the desired result. The technique has been used during the past 7 years on 326 patients, providing satisfactory results with short scars and virtually no complications.
