Low-set ears
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.
Low-set ears can be associated with conditions such as:
- Down syndrome
- Turner syndrome
- Noonan syndrome
- Patau syndrome
- DiGeorge syndrome
- Cri du chat syndrome
- Edwards syndrome
- Fragile X syndrome
- Okamoto syndrome
It is usually bilateral, but it can be unilateral in Goldenhar syndrome.
