Imaging Studies
Atresia repair candidacy is dictated largely by radiographic findings of the middle ear space, and a temporal bone CT scan is essential in the future.

Other Tests
Formal audiography is prudent to document the level of hearing of both the microtic and uninvolved ear. A patient with bilateral atresia requires a bone conduction hearing aid that is placed as soon as possible and replaced often during infancy for speech and language development. [15]

A: Hillocks of His. B: Derivatives of the hillocks of His. The first 3 hillocks are derived from the first pharyngeal arch. The last 3 hillocks are derived from the second pharyngeal arch. The first hillock forms the tragus; the second forms the helical crus; the third forms the helix; the fourth and fifth form the antihelix; and the sixth forms the antitragus.
