[Congenital anomalies of the external ear].

This review describes congenital anomalies of the external ear, which are common and include a wide range of malformations. Attentiveness to other malformations in newborns with ear anomalies is important, as they often appear as part of syndromes such as Goldenhar syndrome, Treacher Collins syndrome and branchio-oto-renal syndrome. This review is an overview of the most common congenital anomalies of the external ear and their treatment, including microtia, constricted ears, preauricular pits, tags and prominent ears.
