Histopathology of atresia auris congenita

ATRESIA auris congenita is not uncommon in clinics and is usually combined with malformations of the auricle and the middle ear. In spite of greatlyincreased interest in the surgical treatment of this congenital disorder, little has been added to our knowledge of the anatomical changes in congenital atresia of the ear. Histopathological reports on this condition are very few in the literature because of the difficulty in obtaining temporal bones from patients with this congenital disorder. The purpose of this paper is to document a histopathological report on congenital atresia of the ear and to discuss its pathogenesis.
