A 73-year-old man was treated surgically for a 20×18mm granulomatous hemorrhagic squamous cell carcinoma on the posterior aspect of the middle third of the helix. Tumor excision with a 7-8mm margin including subjacent cartilage left a rectangular skin defect on the anterior surface and a wedge shaped skin defect on the posterior. The width of the helical defect was 3.5mm.A chondrocutaneous advancement flap, as described by Antia, was modified conform to the arterial supply to the ear. The auricular segmental defect was repaired successfully with a wider chondrocutaneous helical flap than that described by Antia. The reconstructed ear was reduced by 9mm longitudinally and 2mm transversely, with the lobulus 6mm shorter than its original size.No signs of recurrence were visible seven month after surgery.
