The third crus of the antihelix is a very rare anomaly that is characterized by an abnormal elevation of cartilage extending from antihelx to helix. that results in an additional prominence with varying degrees of an helical deformity. In this report, an unusual a 16-years- old male case of a third and fourth crus of the antihelix accompanying constricted helical deformity on upper pole is presented and the surgical correction of the deformity is described. A curvilinear incision is made on the posterior surface of the ear and the skin flap was reflected. In order to correct deformity of the helix and make the scapha concave, a series of additional scoring were made into the extra crus cartilage, and the cartilage was sutured by a few horizontal mattress sutures. For structural support, Medpor was placed on the scapha. Through-and-through mattress sutures are tied over a bolster of gauze for 2 weeks to eliminate dead space and to accentuate the helical sulcus. During the 9 month follow-up, the result was satisfactory.
