It is hard to say what the reason may be, perhaps swelling. However,its critical to understand the basis for abdominal six pack etching. When a patient requests detailed abdominal etching to create an end result of a full “six pack” look, I have repeated emphasized that it is important that the patient already have a full six-pack palpable on examination. The rationale is simple: the detailed differential liposculpture plan requires and is designed along the preexisting anatomy. In other words, abdominal etching “accentuates” the pre-existing three tendinous intersections of the rectus abdominus muscle: one at the xiphoid, one at the umbilicus, and another in between these two regions, as well as the linea alba and semilunar crescents. The plastic surgeon must follow the pre-existing curves of the six pack in his liposculpture to obtain not only a natural result, but a result that is enhanced with further exercise. Otherwise further exercise and weight loss will tend to display the preexisting inscriptions of the rectus definition and to simultaneously compete with the artificially placed “overly symmetric six-pack, stamped-on design” that doesn’t follow your own true anatomy. This lack of respect for the pre-existing (often asymmetric) six-pack anatomy of the patient leads to poor results long term for the devoted body builder, seeking to max out his look. Chances are your surgeon did precisely this, and as the swelling resolves your six pack will regain its prior definition. At the end of the day, it’s critical that anyone contemplating abdominal etching have an individualized consultation with a board certified plastic surgeon whose aesthetic perspective, personality, educational background, talent, training and experience with your needs and wants makes you comfortable, and you believe can help you achieve your aesthetic goals I wish you well in your recovery and end result of an envied six-pack abdomen!
