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. Low-set ears are defined as outer ears positioned two or more standard deviations lower than the population average. Clinically, if the point at which the helix of the outer ear meets the cranium is at or below the line connecting the inner canthi of eyes(bicanthal plane), the ears are considered low set.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 syndromeIt is usually bilateral, but it can be unilateral in Goldenhar syndrome.
