| 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) |
| unilateral | <anatomy> Affecting only one side. Origin: L. Latus = side (18 Nov 1997) |
| unilateral anaesthesia | <neurology> The inability to feel touches (tactile sensations) on one side of the body. (09 Oct 1997) |
| unilateral hemianopia | Uniocular hemianopia, loss of sight in one-half of the visual field of one eye only. (05 Mar 2000) |
| unilateral hermaphroditism | Hermaphroditism in which the doubling of sex characteristics occurs on one side only: ovotestis on one side and either ovary or testis on the other. (05 Mar 2000) |
| unilateral hyperlucent lung | Chronic bronchiolitis obliterans predominating on one side. See: unilateral lobar emphysema. (05 Mar 2000) |
