The earlobes of children and young adults are normally smooth. Creases are sometimes linked with conditions that are passed down through families. Other genetic factors, such as race and earlobe shape, may also determine who develops earlobe creasing and when it occurs. Note: It is not uncommon to have one small abnormality in facial features, such as an earlobe crease. Most often this does not indicate a serious medical condition.
