Abstract: A medical dressing and method for applying within a gluteal cleft of a human buttocks. The first and second cheeks of a human buttocks are manually spread and a foam member is positioned intermediate therebetween. The foam member has a substantially angular cross-sectional profile along a central axis thereof, the dimensions of the angular cross-sectional profile suitable for the foam member to be placed in the gluteal cleft. After positioning, the first and second cheek are released, whereby the foam member is fixedly-held in the gluteal cleft. The foam member can be flexible about the central axis, whereby it can conform to the curvature of the gluteal cleft. The foam member can include channels to increase the surface area and provide a conduit for the dispersion of fluids, and holes to provide conduits for the propagation of fluids to the interior of the foam member.
