1. A negative pressure wound treatment apparatus, comprising:
- a wound dressing comprising a backing layer and a stabilizing structure positioned below the backing layer, wherein the backing layer and the stabilizing structure are configured as a single unit for placement simultaneously over a wound, and wherein the stabilizing structure is configured for placement over skin surrounding the wound;
a port for communicating negative pressure to the wound dressing;
wherein the stabilizing structure is configured to collapse significantly more within a horizontal plane than within a vertical plane to apply a horizontal force to the skin surrounding the wound when the wound dressing is placed under negative pressure; and
an absorbent layer comprising a plurality of through holes, at least some of the plurality of through holes filled with a plug material to provide the absorbent layer with increased vertical rigidity.
