With this method, it was possible to prepare the pectoralis major myocutaneous flap using a small, thin skin paddle with stable blood circulation. Breast deformation, particularly in female cases, was also kept to a minimum.

Unlike the conventional pectoralis major myocutaneous flap, the PP flap does not contain in its skin paddle the pectoralis major muscle and the mammary gland, making it possible to produce a thin flap. In addition, the development of this method has now substantially extended the reach of the flap, thereby making it possible for the PP flap to reach the oropharyngeal region and for the DPP flap to reach the frontal region at a single time. Originally, the skin over the precordium is relatively thin and flexible and provides a desirable color-texture match to facial and neck skin; therefore, it is believed that this method may serve as an extremely useful means in the future in the functional and cosmetic reconstruction of the head and neck region.
