Congenital abnormalities of the ear are common and largely affect the shape of the auricle. Acquired entities can further be delineated into intrinsic processes such as cancer and extrinsic processes such as trauma. An inner concentric ridge the antihelix surrounds the concha and.

It is enclosed by special skin on its anterior and posterior parts and it is essential to the ear for its esthetic anatomical and functional aspects.
