To explore the surgical treatment and pathologic mechanism of polyotia.
The operative methods for polyotia were flexible. The main procedures were aimed at the remodeling of tragus with the redundant tissue. Tissue transplantation was used to correct the depression deformity. Compound auricular tissue transplantation and Z-plasty were used for correction of the malformation at the posterior part of polyotia.
From 2003 to 2008, 9 patients with polyotia were treated. The tragus was reconstructed after resection of redundant tissue. The depression deformity was corrected with tissue infilling in 6 cases. The compound auricular tissue transplantation was performed in 4 cases. Z-plasty at the lower ear lobe was performed in 2 cases. The appearance and the location of the reconstructed ears looked symmetric to the healthy ear.
Natural and symmetric appearance of reconstructed ear can be achieved in polyotia. The abnormal migration of neural crest cell might be the pathologic mechanism of polyotia.
探讨副耳的手术治疗方法及病理机制。
副耳的手术方法灵活多样。主要手术步骤是利用多余组织重塑耳屏。采用组织移植矫正凹陷畸形。应用复合耳廓组织移植及Z成形术矫正副耳后部畸形。
2003年至2008年，共治疗9例副耳患者。切除多余组织后重建耳屏。6例通过组织填充矫正凹陷畸形。4例行复合耳廓组织移植。2例在下耳垂行Z成形术。再造耳的外观及位置与健侧耳对称。
副耳再造可获得自然、对称的外观。神经嵴细胞异常迁移可能是副耳的病理机制。
