hearing condition
pinna
external ear:
auricle (little ear); projected part of the external ear
(pinna=feather)
external auditory canal
external ear:
external passage for sounds collected from the pinna to the tympanum
cerumen
external ear:
waxy substance secreted by glands located throughtout the external canal
tympanic membrane (TM)
middle ear:
eardrum; drumlike structure that reveives sound collected in the external auditory canal and amplifies it through the middle ear
malleus
middle ear:
hammer; first of the three auditory ossicles of the middle ear
incus
middle ear:
anvil; middle of the three auditory ossicles of the middle ear
stapes
middle ear:
stirrup; last of the three auditory ossicles of the middle ear
eustachian tube
auditory tube
middle ear:
tube connecting the middle ear to the pharynx (throat)
oval window
membrane that covers the opening between the middle ear and the inner ear
labyrinth
inner ear:
maze; inner ear consisting of bony and membranous passages
cochlea
inner ear:
coiled tubular structure of the inner ear that contains the organ of corti
(cochlea=snail)
perilymph
inner ear:
fluid that fills the bony labyrinth of the inner ear
endolymph
inner ear:
fluid within the cochlear duct of the inner ear
organ of corti
inner ear:
organ located in the cochlea; contains receptors (hair cells) that receive vibrations and generate nerve impulses for hearing
vestibule
inner ear:
middle part of the inner ear in front of the semilunar canals and behind the cochlea that contains the utricle and the saccule
utricle
inner ear:
larger of two sacs within the membranous labyrinth of the vestibule in the inner ear (uter = leather bag)
saccule
inner ear:
smaller of two sacs within the membranous labyrinth of the vestiblue in the inner ear
(sacculus = small bag)
semicircular canals
inner ear:
three canals within the inner ear that contain specialized receptor ce-lls that generate nerve impulses with body movement
anacusis
total hearing loss
otalgia
otodynia
earache
otorrhagia
bleeding from the ear
otorrhea
purulent drainage from the ear
paracusis
impaired hearing
tinnitus
a jingling; ringing or buzzing in the ear
vertigo
a turning round; dizziness
otitis externa
inflammation of the external auditiory canal
cerumen impaction
excessive buildup of wax in ear, often reducing hearing acuity, especially in elderly persona
myringitis
tympanitis
inflammation of the eardrum
otitis media
inflammation of the middle ear
aerotitis media
inflammation of the middle ear from changes in atmospheric pressure; often occurs in frequent air travel
eustachian obstruction
blockage of the eustachian tube usually as a result of infection, as in otitis media
labyrinthitis
inflammation of the labyrinth
(inner ear)
otosclerosis
hardening of the bony tissue in the ear
deafness
general term for partial or complete hearing loss
conductive hearing loss
hearing impairment caused by interference with sound or vibratory energy in the external canal, middle ear, or ossicles
sensorineural hearing loss
hearing impairment caused by lesiosn or dysfunctionn of the cochlea or auditory nerve
presbyacusis
presbycusis
hearing impairment in old age
audiometry
process of measuring hearing
audiologist
health professional who specialized in the study of hearing impairments
auditory acuity testing
physical assessment of hearing
differentiating between conductive and sensorineural hearing loss
tuning fork
two pronged forklike instrument, used to test hearing, 'specialy bone conduction
otoscopy
use of an otoscope to examine the external auditory canal and tympanic membrane
tympanometry
measurement of the conductibility of the tympanic membrane and ossicles of the middle ear by monitoring the response to external airflow pressures
microsurgery
surgery with the use of a microscope
myringotomy
incision into the eardrum, most often for insertion of a small polyethylene (PE) tube to keep the canal open and prevent fluid buildup, such as occurs in otitis media
otoplasty
surgical repair of the external ear
stapedectomy
excision of the stapes to correct otosclerosis
tympanoplasty
vein graft of a scarred tympanic membrane to improve sound conduction
ear lavage
irrigation of the external ear canal, often to remove excessive buildup of cerumen
ear instillation
introduction of a medicaled solution into the exteral canal, usually administered by drop (gt) or drops (gtt) in the affected ear

AD right ear
AS left ear
AU both ears
