One case was that in which there was congenital absence of the external auditory meatus of both ears without much impairment of hearing.

In neither ear of N.W.Goddard, aged twenty-seven, of Vermont, reported in 1834, was there a vestige of an opening or passage in the external ear, and not even an indentation.
The Eustachian tube was closed.

The integuments of the face and scalp were capable of receiving acoustic impressions and of transmitting them to the organs of hearing.

The authors know of a student of a prominent New York University who is congenitally deficient in external ears, yet his hearing is acute.

He hides his deformity by wearing his hair long and combed over his ears.
The knowledge of anomalous auricles is lost in antiquity.
