| 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) |
| 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, 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, 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, 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) |
| 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) |
| conductive deafness | Hearing impairment caused by interference with sound or transmission through the external canal, middle ear, or ossicles. (05 Mar 2000) |
| conductive heat | Heat transmitted by direct contact, as by an electric pad or hot water bottle. (05 Mar 2000) |
| neoplasms, complex and mixed | Neoplasms composed of more than one type of neoplastic tissue. (12 Dec 1998) |
| american speech-language-hearing association | A professional society concerned with the diagnosis, prevention, treatment, and remediation of speech, language, and hearing disorders. (12 Dec 1998) |
