Accessory tragus is a fairly common congenital malformation of the external ear. In the vast majority of cases it is an isolated developmental defect not associated with other abnormalities. However, the remote possibility exists that it could be associated with other abnormalities of the first and second branchial arch. Accessory tragus is a consistent feature of the oculoauriculovertebral syndrome (Goldenhar syndrome). When correctly identified, surgical excision of accessory tragus is quite simple and rarely results in any complications.
副耳是一种相当常见的外耳先天性畸形。在绝大多数情况下，它是一种孤立的发育缺陷，与其他异常无关。然而，仍存在极微小的可能性，它可能与第一和第二鳃弓的其他异常有关。副耳是眼耳脊椎综合征（Goldenhar综合征）的一个特征性表现。当正确识别后，副耳的手术切除相当简单，很少会导致任何并发症。
