    Abstract:
    Constricted ear deformity was first described by Tanzer and classified it into 3 groups according to the degree of constriction. The group IIB deformity involves the helix, scapha, and antihelical fold. The height of the ear is sharply reduced, and the soft tissue envelope is not sufficient to close the cartilage framework after expansion and reshaping.This study describes expanding the cartilage and increasing the height by advancing the helical root superiorly and repairing the skin-cartilage defect with a superior auricular artery chondrocutaneous flap in Tanzer group IIB constricted ear deformity.Six ears of 6 patients were treated with this technique during the past 3 years. All patients were satisfied with the appearance of their corrected ears, and the increase in height was maintained through the follow-up period.The described technique does not have the disadvantages and possible complications of harvesting a costal cartilage graft. Moving and fixing the root of helix to a more superior position provide the auricle with additional length. The superior auricular artery chondrocutaneous flap not only provides adequate soft tissue for primary closure of the anterior portion of the auricle but also aids in repairing the cartilage defect resulting from the superior advancement of the helix as well.
