| retrocochlear deafness | Former term for sensorineural deafness; suggesting a lesion proximal to the cochlea. (05 Mar 2000) |
|---|---|
| perceptive deafness | Former term for sensorineural deafness. (05 Mar 2000) |
| Mondini deafness | The hearing loss resulting from the structural aberration of Mondini dysplasia. (05 Mar 2000) |
| conductive deafness | Hearing impairment caused by interference with sound or transmission through the external canal, middle ear, or ossicles. (05 Mar 2000) |
| word deafness | An impairment in comprehension of the auditory forms of language and communication, including the ability to write from dictation in the presence of normal hearing. Spontaneous speech, reading, and writing are not affected. Synonym: acoustic aphasia, word deafness. (05 Mar 2000) |
| cortical deafness | Deafness resulting from bilateral lesions of the primary receptive area of the temporal lobe. (05 Mar 2000) |
| postlingual deafness | Hearing impairment occurring after speech and language skills have been developed. (05 Mar 2000) |
| prelingual deafness | Hearing impairment occurring before development of speech and language skills. (05 Mar 2000) |
| hereditary deafness and nephropathy | <nephrology, pathology> An inherited disorder involving damage to the kidneys, haematuria and hearing loss. In some individuals vision may also be affected. This genetic disease is uncommon. Symptoms include loss of hearing, abnormal colour to urine, swelling, cough and decline in vision. Inheritance: sex-linked autosomal dominant. Incidence: 1 in 50,000. Origin: Gr. Pathos = disease (27 Sep 1997) |
| Scheibe's deafness | Deafness (may be unilateral) due to cochleosaccular dysplasia; usually autosomal recessive inheritance. (05 Mar 2000) |
| high frequency deafness | Selective loss of hearing acuity for high frequencies, usually associated with neurosensory damage; common in acoustic trauma. (05 Mar 2000) |
| psychogenic deafness | Hearing loss without evidence of organic cause or malingering; often follows severe psychic shock. Synonym: functional deafness, hysterical deafness. (05 Mar 2000) |
| sensorineural deafness | Hearing impairment due to disorders of the cochlear division of the 9th cranial nerve (auditory nerve), the cochlea, or the retrocochlear nerve tracts, as opposed to conductive deafness. (05 Mar 2000) |
| hysterical deafness | Hearing loss without evidence of organic cause or malingering; often follows severe psychic shock. Synonym: functional deafness, hysterical deafness. (05 Mar 2000) |
| nerve deafness | Neural deafness, former terms for sensorineural deafness. (05 Mar 2000) |
