The Superficial Inferior Epigastric (SIE) flap results in the same natural breast that is created with the DIEP flap.  The tissue that is utilized is the same skin and fat.  What is different is that the blood vessels for this flap are superficial.  The vessels are above the muscle and fascia. Not only is no muscle utilized, but even better, the muscle is not manipulated at all.  The advantage is an even faster recovery and zero risk of hernia.

Why doesn't everyone have a SIE flap?  The reason is because many times the Superficial Inferior Epigastric vessels are too tiny to utilize. Also, often they are not the dominant blood supply to the skin and fat that is utilized to make the breast.  With doppler ( a fancy stethoscope) exam done before surgery, Dr. Keller can predict if these vessels will be appropriate.  The final determination is made in the operating room.
