deafness

 [def´nes]
hearing loss; lack or loss of all or a major part of the sense of hearing. For types, see under hearing loss.
Alexander's deafness congenital deafness due to cochlear aplasia involving chiefly the organ of Corti and adjacent ganglion cells of the basal coil of the cochlea; high-frequency hearing loss results.
central deafness that due to causes in the auditory pathways or in the brain; see hearing loss.
conduction deafness (conductive deafness) conductive hearing loss.
functional deafness functional hearing loss.
hysterical deafness functional hearing loss.
pagetoid deafness that occurring in osteitis deformans of the bones of the skull (paget's disease).
sensorineural deafness
1. that due to a defect in the inner ear or the acoustic nerve. See hearing loss.
word deafness auditory aphasia.

sen·so·ri·neu·ral deaf·ness

(sen'sōr-ē-nūr'ăl def'nĕs)
Hearing impairment due to disorders of the cochlear division of cranial nerve VII (auditory nerve), the cochlea, or the retrocochlear nerve tracts, as opposed to conductive deafness.

sensorineural deafness

Deafness caused by any defect in the inner ear mechanism that converts sound vibrations into nerve impulses, especially the hair cells of the cochlea, or in the acoustic nerve (8th cranial nerve) or the brain. Compare CONDUCTIVE DEAFNESS.

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.

Case reports were aggregated into four mutually exclusive defect categories: 1) brain abnormalities or microcephaly (defined as head circumference at delivery <3rd percentile for sex and gestational age); 2) NTDs and other early brain malformations (these are included as biologically plausible but have been reported much less frequently with Zika virus infection than those in category 1); 3) eye abnormalities (without mention of a brain abnormality in categories 1 or 2); and 4) other consequences of CNS dysfunction, specifically joint contractures and congenital sensorineural deafness, without mention of brain or eye abnormalities included in any other category.
