Preparation of the tissue flap and free skin graft. A 2 cm × 3 cm-sized temporal muscle flap and a mastoid fascia flap of approximately 4 cm × 4 cm was made (A). The temporal muscle flap was turned over and passed through the skin above the highest point of the auricle to cover the surface of the exposed framework. The mastoid fascia flap was turned forward to the concha, and the epidermal skin graft was transplanted onto their surface. A mini drainage was left under the scalp and auricle, and the cavity was then closed (B)
