Tracheal reconstruction using S-shaped skin flaps and a conchal cartilage graft.

We have devised a technique of two-stage tracheal reconstruction using S-shaped skin flaps and an aural conchal cartilage graft. During the first operation, S-shaped skin flaps were elevated before resection of the trachea. A tracheocutaneous fistula was created at the tracheal defect using S-shaped skin flaps while placing the conchal cartilage graft underneath. During the second operation, a skin incision was made around the fistula to elevate the hinge flaps, including the cartilage. The edges of the hinge flaps were sutured to form the tracheal lumen, and the area of the skin defect was then closed with double-rotation skin flaps.
