Plastic surgery of the abdomen with improvement in the body contour. Physiopathology and treatment of the aponeurotic musculature.

The author presents the evolution of his technique of undermining the major oblique musculature to reduce the diameter of the waist and also reduce the diameter of the superior abdomen by resecting cartilage from the seventh and eighth ribs when the anterior projection is exaggerated. Treatment of the aponeurotic muscle wall plays an important role in obtaining good aesthetic results because this wall will serve as a base for the cutaneous tegument upon healing.
