Construction of the nipple with a mushroom-shaped pedicle.

Construction of the nipple-areolar complex has been the subject of much interest and many papers. We believe that the best way to ensure nipple protrusion is by the entrapment of tissue above the skin surface so that it cannot retract. This, in principle, is similar to creating an irreducible hernia. This technique for nipple construction employs a circular split-thickness island of skin which has its central circulation preserved through its attachment at the new nipple site. This central stalk represents about one-quarter of the total surface area of the constructed areola. The total diameter of the areolar disk is usually determined by the size of the opposite nipple-areolar complex. The new areola is developed from a full-thickness skin graft taken from the area below the inguinal crease. Once removed, it is sutured over the elevated nipple segment with its central island. The full-thickness graft is sutured into place before a small cruciate incision is made in the center. It should be just large enough to permit the delivery of the dermal-epidermal flap on its stalk up through the opening. Nothing more need be done to the raw undersurface of the split-thickness skin. Its raw surface has no place to reattach because its bed is now covered with the full-thickness graft.(ABSTRACT TRUNCATED AT 250 WORDS)
