former terms for sensorineural hearing loss.

nerve deafness

nerve deafness

Hearing loss resulting from damage to the transducers in the inner ear (Organ of Corti) or to the acoustic nerve connections to the brain, rather than from mechanical interference with the transmission of sound vibrations to the inner ear (conductive deafness).


lack or loss, complete or partial, of the sense of hearing.

conductive deafness
sound vibrations are interrupted in the outer or middle ear and do not reach the inner ear and its nerve endings.
congenital deafness
infrequent in dogs and cats, not recorded in other species. In most cases is due to cochlear duct degeneration. See also inherited deafness (below).
cortical deafness
that due to disease of the cortical centers of the cerebrum.
inherited deafness
occurs in some blue-eyed white cats and in some dog breeds; particularly common in the Dalmatian. In some cases it is associated with coat coloration, e.g. white Bull terriers, merle collies and Old English sheepdogs.
nerve deafness
due to degeneration of the acoustic sensory organ. Most common in dogs at an early age and associated with incomplete pigmentation of the haircoat and the uvea, in animals with a white or merle coat color. Occurs also in mink, cats and mice.
sensorineural deafness
due to damage of the inner ear nerve endings, the cochlear portion of the eighth cranial nerve, the vestibulocochlear nerve, or the cortical hearing center. See also nerve deafness (above).
toxic deafness
overdosing with aminoglycoside antibiotics causes deafness.
transmission deafness
conductive hearing loss.
