Description

The otoscope examination of the ear is often difficult in cases of Down's syndrome, although they are often associated with hearing loss and otitis media. We present temporal bone histopathologic findings of the external auditory meatus and middle ear in a new born caseof Down's syndrome. The external auditory meatus was narrow forming the very sharp angle with tympanic membrane and mesenchyme tissue remained in the middle ear, which suggested difficulty of otoscope examination of the ear. Audiogram, in clinical settings CT scan of the temporal bone and other examinations were considered to be necessary for the accurate diagnosis and adequate treatment of the ears in the case of Down's syndrome.
