When an auricular defect is caused by high‐energy trauma that causes damage to the surrounding tissues, the patient may be not a candidate for reconstruction with local flaps and free tissue transfer may be necessary. Here we present a case of total auricular reconstruction in a 27 year‐old man who had total loss of the left ear and traumatized temporal skin and fascia. A radial forearm flap prelaminated by a porous polyethylene implant was employed. A “printed” ear made of silicone, based on the patient's CT‐scan of the contralateral ear, was used for intraoperative molding of the future reconstruction. Prolonged prelamination time and surgical delay (three months) were performed to reduce edema, distortion and loss of definition of the framework after revascularization. After subsequent integration and neovascularization of the added tissue, the prelaminated flap was transferred. Flap reinnervation was also performed by direct coaption of the great auricular nerve to the lateral antebrachial cutaneous nerve. The flap fully survived and there were no complications in the early postoperative period. Between 3 and 6 months, the patient returned to normal ranges in terms of warmth and cold, and recovered the discriminative facial sensibility. After one year the auricular reconstruction was intact and satisfactory aesthetic results were achieved. This method may offer a satisfactory solution for a difficult problem and may be considered for acquired total ear defects.
