Constricted ears are characterized by four features: (a) lop deformity, (b) protrusion, (c) low ear position, and (d) decreased ear size. These deformities, resulting from inadequate length of the helix, have been described by Tanzer (1975) as a purse-string closure of the ear. Constricted ears are classified into types 1, 2, and 3 according to the severity of the deformity. Type 3 constricted ear, the most severe, with decreased size and loss of the upper half of the normal ear contour, is classified currently as a mild form of microtia. Therefore, autogenous rib cartilage was used to reconstruct the affected ear much as in correction of microtia. The expanded skin flap in the mastoid area was used to reconstruct auricles for 14 patients with type 3 constricted ear in the authors' center from 2001 to 2004. All the patients were satisfied with the final results. Therefore, the authors conclude that their operative technique is practical and reliable.
(a) 耳廓下垂畸形，(b) 耳廓突出，(c) 耳部位置低，以及(d) 耳部尺寸减小。这些畸形是由于耳轮长度不足所致，Tanzer（1975年）将其描述为耳部的束带样闭合。招风耳根据畸形的严重程度分为1型、2型和3型。3型招风耳最为严重，耳部尺寸减小且正常耳廓轮廓的上半部分缺失，目前被归类为轻度小耳畸形。因此，自体肋软骨被用于重建患耳，这与小耳畸形矫正的方法大致相同。2001年至2004年，作者所在中心使用乳突区的扩张皮瓣为14例3型招风耳患者重建耳廓。所有患者对最终结果均满意。因此，作者得出结论，他们的手术技术实用且可靠。
