The most frequent malignancy of the auricle is squamous cell carcinoma. Resection of auricular squamous cell carcinoma results in over one-third or one-fourth of auricular skin and cartilage defects. We experienced a case in which one half of the auricular skin and cartilage defects were due to auricular squamous cell carcinoma resection (T2N0M0 stage II) . We performed staged reconstruction of the auricle with the aim of auricular appearance and the functional purpose of wearing eyeglasses. We carried out auricular reduction in the affected side and cartilaginous graft transplantation from the unaffected side. Auricular wedge-shaped closure, chondrocutaneous advancement flap, temporoparietal fascial flap and split-thickness skin graft techniques were also employed.One year after the auricular reconstruction, tumor recurrence and distal metastasis has not been observed. The reconstructed auricle is smaller than the unaffected auricle and has some deformity. However, the patient can wear eyeglasses. [Skin Cancer (Japan) 2008; 23: 384-389]
