Anomalies of the Ears.--Bilateral absence of the external ears is quite
rare, although there is a species of sheep, native of China, called the
"Yungti," in which this anomaly is constant. Bartholinus, Lycosthenes,
Pare, Schenck, and Oberteuffer have remarked on deficient external
ears. Guys, the celebrated Marseilles litterateur of the eighteenth
century, was born with only one ear. Chantreuil mentions obliteration
of the external auditory canal in the new-born. Bannofont reports a
case of congenital imperforation of the left auditory canal existing
near the tympanic membrane with total deafness in that ear. Lloyd
described a fetus showing absence of the external auditory meatus on
both sides. Munro reports a case of congenital absence of the external
auditory meatus of the right ear; and Richardson speaks of congenital
malformation of the external auditory apparatus of the right side.
There is an instance of absence of the auditory canal with but partial
loss of hearing. Mussey reports several cases of congenitally deficient
or absent aural appendages. 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. Figure 103
represents the head of an aegipan in the British Museum showing a
supernumerary auricle. As a rule, supernumerary auricles are
preauricular appendages. Warner, in a report of the examination of
50,000 children, quoted by Ballantyne, describes 33 with supernumerary
auricles, represented by sessile or pedunculated outgrowths in front of
the tragus. They are more commonly unilateral, always congenital, and
can be easily removed, giving rise to no unpleasant symptoms. They have
a soft and elastic consistency, and are usually composed of a hyaline
or reticular cartilagin
