| 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) |
| noise-induced deafness | A type of sensorineural deafness caused by prolonged exposure to loud sounds, e.g., jet engines. (05 Mar 2000) |
| deafness | A condition in which the sense of hearing in both ears is not functional for ordinary purposes of life. The hearing level for speech is approximately 71 decibels I.s.o. (international organization for standardization) or 61 db a.s.a. (american standards association) or greater. (12 Dec 1998) |

| industrial deafness | Synonym: acoustic trauma deafness. (05 Mar 2000) |
| occupational deafness | Sensorineural hearing loss due to overexposure to high intensity noise levels. Synonym: boilermaker's deafness, industrial deafness, occupational deafness. (05 Mar 2000) |
| organic deafness | Deafness due to a pathologic process or an organic aetiology, as opposed to psychogenic deafness. (05 Mar 2000) |
| functional deafness | Hearing loss without evidence of organic cause or malingering; often follows severe psychic shock. Synonym: functional deafness, hysterical deafness. (05 Mar 2000) |
| low tone deafness | Inability to hear low notes or frequencies. (05 Mar 2000) |
| communicating branches of auriculotemporal nerve to facial nerve | <anatomy, nerve> Branches conveying fibres from the auriculotemporal nerve to the facial nerve. Synonym: rami communicantes nervi auriculotemporalis cum nervo faciali. (05 Mar 2000) |
| communicating branches of lingual nerve to hypoglossal nerve | <anatomy, nerve> Communicating branches between the lingual nerve (from mandibular nerve) and hypoglossal nerve forming a plexus on the hypoglossus muscle. Synonym: rami communicantes nervi lingualis cum nervo hypoglosso. (05 Mar 2000) |
