Low-set ears are ears with depressed positioning of the pinnae two or more standard deviations below the population average.[1]

It can be associated with conditions such as:

It is usually bilateral, but it can be unilateral in Goldenhar syndrome.[6]

A lethal form of low-set ears manifests in otocephaly, a very rare disorder characterized by absence of the mandible (agnathia) and partial or total merging of the ears at the midline (synotia). Due to the extent of craniofacial malformations, fetuses with otocephaly never survive to birth. Otocephaly occurs 1 in every 70,000 embryos.[7]
