One of Dr Ralph Millard’s basic principles of plastic surgery is to “know the beautiful normal.” Dr Pedro Cormenzana helps us understand the normal anatomy of the abdomen, specifically the relationships of the umbilicus, suprapubic scar, and pubis. Aesthetic plastic surgery results are hard to judge because much too often they are subjectively judged. Determining the norm, with its variations, gives surgeons an opportunity to judge their work against an objective measure. Through his keen observation and attention to detail, Dr Cormenzana has determined a set of measurements that can help surgeons plan their surgical procedures and judge the deformities that may present after primary abdominoplasty. As is the case for all the articles in this issue of Clinics in Plastic Surgery , “Revision Abdominoplasty and Proper Umbilical Positioning” is essential reading for beginning surgeons as well as experienced surgeons.
