| acoustic trauma deafness | Sensorineural hearing loss due to overexposure to high intensity noise levels. Synonym: boilermaker's deafness, industrial deafness, occupational deafness. (05 Mar 2000) |
|---|---|
| conductive hearing loss | <otolaryngology> A form of deafness that results from a blockage of the ear canal or dysfunction of the ossicles or eardrum (sound collecting apparatus). In conductive hearing loss the auditory nerve is normal, but there exists a physical problem with the sound collecting apparatus. (05 Jan 1998) |
| hearing loss, bilateral | Partial hearing loss in both ears. (12 Dec 1998) |
| hearing loss, central | Hearing loss due to central nervous system disease, anywhere in the auditory pathways from the cochlear nucleus of the pons to the auditory cortex. (12 Dec 1998) |
| hearing loss, conductive | Hearing loss due to interference with the acoustic transmission of sound to the cochlea. The interference is in the outer or middle ear. (12 Dec 1998) |
| hearing loss, functional | Hearing loss without a physical basis. (12 Dec 1998) |
| hearing loss, high-frequency | Hearing loss in frequencies above 1000 hertz. (12 Dec 1998) |
| hearing loss, noise-induced | Hearing loss from exposure to noise. The loss is often in the frequency range 4000-6000 hertz. (12 Dec 1998) |
| hearing loss, partial | A condition in which the sense of hearing, although defective, is functional with or without a hearing aid. The hearing level for speech is approximately 40-70 decibels I.s.o. (international organization for standardization) or 30-60 db a.s.a. (american standards association). (12 Dec 1998) |
| hearing loss, sensorineural | Hearing loss resulting from damage to the sensory mechanism internal from the oval and round windows. (12 Dec 1998) |
| sensorineural hearing loss | <neurology> A form of deafness that occurs due to dysfunction of the auditory nerve (cranial nerve VIII). (27 Sep 1997) |
| birth trauma | Physical injury to an infant during its delivery, the supposed emotional injury, inflicted by events incident to birth, upon an infant which allegedly appears in symbolic form in patients with mental illness. Trauma from occlusion, a reversible lesion in the periodontium caused by excessive movement of teeth. Occlusal trauma, abnormal occlusal stresses capable of producing or which have produced pathologic changes in the tooth and its surrounding structures. Psychic trauma, an upsetting experience precipitating or aggravating an emotional or mental disorder. (05 Mar 2000) |
| multiple trauma | Physical insults or injuries occurring simultaneously in several parts of the body. (12 Dec 1998) |
| cumulative trauma disorders | Harmful and painful condition caused by overuse or overexertion of some part of the musculoskeletal system, often resulting from work-related physical activities. It is characterised by inflammation, pain, or dysfunction of the involved joints, bones, ligaments, and nerves. (12 Dec 1998) |
| oesophageal trauma | <radiology> Emetic trauma: mucosal: Mallory-Weiss syndrome, intramural: intramural dissection, transmural: Boerhaave syndrome, non-emetic trauma: instrumentation, blunt trauma to chest, penetrating trauma, taco tear (12 Dec 1998) |
