Congenital malformations of the auricle are the result of a series of insults during the embryologic development of fetal auricular cartilage. Various anomalies described in the literature include microtia, aural atresia, prominent auricles, preauricular pits, and accessory auricular appendages. These anomalies have varying degrees of functional impairment and severity, which may or may not require surgical intervention. In addition, these aberrations can be associated with other congenital syndromes, however are most often found in isolation. Management involves recognizing the benefits and limitations of therapy, which should be thoroughly discussed with the parents and, when appropriate, the patient. Here, we present an overview of the anomalies of the external ear.
