Sumario: | The anatomic position of the auricle leaves it vulnerable to traumatic lesions. In most cases, the best reconstructive outcome is accomplished using a temporoparietal flap with a costal cartilage frame and a partial thickness skin graft. Exceptional cases may require different approaches because the reconstructive goals could be more structural than aesthetic. An important factor in this regard is the mechanical properties of the skin that will provide coverage. This study aimed to share a particular case of total auricular reconstruction assisted by 3D surface imaging and 3D printing in a radial forearm free flap. We present a 58-year-old man with a history of having tympanic barotrauma causing hearing loss, burdening him with the use of auricular devices for hearing assistance. Seven days before presenting for the initial treatment, he sustained ear trauma while performing mechanical reparations in a car. The wheel was activated, causing a total amputation of the right ear. He first went to another hospital‚ where they performed primary closure and then referred him to our unit. The team performed a prelaminated radial forearm free flap assisted by 3D scanning and planning. A detailed comparison between the left ear and the result of the reconstruction was measured and described. The radial forearm prelaminated free flap is a viable structural alternative with the disadvantage of poor auricular definition in some cases. |
