audio
hearing
aero
air or gas
auri
oto
ear
cerumino
wax
salpingo
eustachian tube or uterine tube
tympano
myringo
eardrum
-acusis
hearing condition
pinna
auricle (little ear) projected part of the external ear
external auditory meatus
external passage for sounds collected from the pinna to the tympanum
cerumen
waxy substance secreted by glands located throughout the external canal
tympanic membrane
eardrum; drum-like structure that receives sound collected in the external auditory meatus and amplifies it through the middle ear
malleus
hammer; first of the three auditory ossicles of the middle ear
incus
anvil; middle of the three auditory ossicles of the middle ear
stapes
stirrup; last of the three auditory ossicles of the middle ear
eustachian tube
tube connecting the middle ear to the pharynx
mastoid process
projection of the temporal bone located behind the ear containing air cells that connect to the middle ear
oval window
membrane that covers the openng between the middle ear and the inner ear
inner ear
structures and liquids that relay sound waves to the auditory nerve fibers on a path to the brain for interpretation of sound
labyrinth
maze; inner ear consisting of bony and membranous labyrinths
cochlea
coiled tubular strcuture of the inner ear that contains the organ of Corti
perilymph
fluid that fills the bony labyrinth of the ear
endolymph
fluid within the cochleaer duct of the inner ear
organ of Corti
organ located in the cochlea that contains receptors that receive vibrations and generate nerve impulses for hearing
vestibule
middle part of the inner ear in front of the semicircular canals and behind the cochlea that contains the utricle and saccule
utricle
larger of two sacs within the membranous labyrinth of the vestibule in the inner ear
saccule
smaller of two sacs within the membranous labyrinth of the vestibule in the inner ear
semicircuar canals
three canals within the inner ear that contain specialized receptor cells that generate nerve impulses with body movement
otalgia
otodynia
earache
otorrhagia
bleeding from the ear
otorrhea
purulent drainage from the ear
tinnitus
a jingling; ringing or buzzing in the ear
vertigo
a turning round; dizziness
otitis externa
inflammation of the external auditory meatus
cerument impaction
excessive buildup of wax in the eaer
myringitis
tympanitis
inflammation of the eardrum
otitis media
inflammation of the middle ear
aerotitis media
inflammation of the middle ear from changes in atmostpheric pressure; often occurs in frequent air travel
otosclerosis
hardening of the bony tissue in the ear
mastoiditis
inflammation of the mastoid process; most commonly seen as a result of the spread of inflammation and infection in otitis media
eustachian obstruction
block of the eustachian tube usually as a result of infection, as in otitis media
acousitc neuroma
benign tumor on the auditory nerve (8th cranial nerve) that causes vertigo, tinnitus, and hearing loss
aplasia
condition of absence of malformation of inner ear structures during embryonic development, resulting in hearing loss
labyrinthitis
inflammation of the labyrinth
Meniere disease
disorder of the inner ear due to an excessive buildup of endolymphatic fluid causing episodes of vertigo, tinnitus, nausea, vomiting, and hearing loss; one or both ears can be affected, and attacks vary in frequency and intensity
deafness
genereal term for partial or complete hearing loss
conductive hearing loss
hearing impairment caused by intereference with sound or vibratory energy in the external canal, middle ear, or ossicles
sensorineural hearing loss
hearing impairment caused by lesions or dysfunction of te cochlea or auditory nerve
mixed hearing loss
combination of sensorineural and conductive hearing loss
presbyacusis
presbycusis
hearing impairment of old age
audiometry
process of measuring hearing
audiometer
instrument to measure hearing
audiogram
record of hearing measurement
audiologist
person who specializes in the study of hearing impairments
auditory acuity testing
physical assessment of hearing; useful in differentiating between conductive and sensorineural hearing loss
tuning fork
two pronged, fork-like instrument that vibrates when stuck; used to test for hearing, especially bone conduction
otoscopy
use of an otoscope to examine the external auditory meatus (canal) and tympanic membrane
pneumatic otoscopy
otoscopic observation of the tympanic membrane as air is released into the external auditory meatus; immobility indictes the presence of middle ear effusion as occurs as a result of otitis media
tympanometry
measurement of the compliance and mobility of the tympanic membrane and ossicles of the middle ear by monitoring the response after exposure to external airflow pressure
microsurgery
surger with the use of a microscope used in procedures involving delicate tissue such as the ear
myringotomy
tympanostomy
incision into the eardrum most often for insertion of a small metal or plastic tube to keep the meatus open avoiding fliud builup as that which occurs as a result of otitis media
otoplasty
surgical repair of the external ear
stapedectomy
excision of the stapes to correct ososclerosis
tympanoplasty
vein graft of a scarred tympanic membrane to improve sound conduction
auditory prosthesis
any internal or external device that improves or substitues for natural hearing
hearing aid
external amplifying device designed to improve hearing by more effective collection of sound into the ear
cochlear implant
electronic device implaned in the cochlea that provides sound preceptio to patients with severe or profound sensorineural hearing loss in both eyes
ear lavage
irrigation of the external ear canal, commonly done to remove excessive buildup of cerumen
ear instillation
introduction of a medicated solution into the external canal
