Low-set ears are a clinical feature in which the ears are positioned lower on the head than usual. They are present in many congenital conditions. Specifically, low-set ears are defined as outer ears positioned two or more standard deviations lower than the population average.[1]
Low-set ears can be associated with conditions such as:
- Down syndrome[2]
- Turner syndrome
- Noonan syndrome[3]
- Patau syndrome[4]
- DiGeorge syndrome[5]
- Cri du chat syndrome
- Edwards syndrome
- Fragile X syndrome
- Okamoto syndrome
It is usually bilateral, but it can be unilateral in Goldenhar syndrome.[6]
