ABSTRACT
Although the surgical principles of classic abdominoplasty certainly have stood the test of time, they are based on two theoretical assumptions that may be proved to be inaccurate: 1. Wide direct undermining is essential for flap advancement, and 2. Abdominal skin relaxation occurs in the vertical direction from xiphoid to pubis . . . Discontinuous undermining allows effective loosening of the abdominal flap while preserving vascular perforators, . . . [and] significant lateral truncal skin resection results in epigastric tightening.1
