Figure 1 Sitting patient with NPWT foam dressing: The incision is bent in the inframammary fold, provoking traction forces that would pull apart skin edges. However, NPWT dressing conforms to body contours and helps to hold incision edges together.

Figure 2 Skin incision at removal of foam dressing on postoperative day 6. Despite difficult conditions (bending skin in inframammary fold, skin perspiration, and insulin-dependent diabetes), wound healing was primary and already represents a sufficient barrier to external infectious sources.
