Overview & Considerations
During fetal development, the outer ear or "pinna" forms at a time when many other critical organs are developing (such as the kidneys). Abnormalities in the shape or positioning of the pinna may be an indication that there are other associated abnormalities present.
Common abnormalities include abnormal folds in the pinna, prominence of the ears, low-set positioning, abnormal rotation of the pinna, and even absence of the pinna.
Many children are born with ears that stick out (protruding ears). Although people may comment on the ear shape, this condition is a variation of normal and is not associated with other disorders. However, low-set ears, absent pinna, and abnormal folds may be associated with various medical conditions.
