aur/i, ot/o
ear
cerumin/o
wax
salping/o
eustachian tube or uterine tube
tympan/o, myring/o
eardrum
-acusis
hearing condition
pinna
auricle; projected part of the external ear
external auditory canal
external passage for sounds collected from the pinna to the tympanum
cerumen
a waxy substance secreted by glands located throughout the external canal
tympanic membrane (TM)
eardrum; drum like structure that receives sound collected in the external auditory canal 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 ossicles of the middle ear
stapes
stirrup last of the three auditory ossicles of the middle ear
eustachian tube, auditory tube
tube connecting the middle ear to the pharynx
oval window
membrane that covers the opening between the middle ear and inner ear
labyrinth
maze, inner ear consisting of bony and membranous passages
cochlea
coiled tubular structure of the inner ear that contains the organ of Corti
perilympha
fluid that fills the bony labyrinth of the inner ear
endolymph
fluid within the cochlea duct of the inner ear
organ of Conti
organ located in the cochlea; contains receptors that receive vibrations and generate nerve impulses for hearing
vestibule
middle part of the inner ear in front of the semilunar canals and behind the cochlea that contain the utricle and the saccule
utricle
larger of the two sacs within the membranous labyrinth of the vestibule in the inner ear
saccule
smaller of the two sacs within the membranous labyrinth of the vestibule in the inner ear
semicircular canals
three canals within the inner ear that contain specialized receptor cells 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 auditory canal
cerumen impaction
excessive buildup of wax in ear, often reducing hearing acuity, especially in elderly persons
myringitis, tumpanitis
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
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 lesions of dysfunction of the cochlea or auditory nerve
presbyacusis, presbycusis
hearing impairment in old age
audiometry
process of measuring hearing
audiometer
instrument to measure hearing
audiologist
the health professional 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, forklike instrument that vibrates when struck ; used to test hearing, especially 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 used in delicate tissue such as the ear
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 medicated solution into the external canal, usually administered by drop (gt) or drops (gtt) in the affected ear or ears
antibiotic
drug that inhibits the growth of or destroy microorganisms; used to treat diseases caused by bacteria
antihistamine
drug that blocks the effects of histamine
histamine
a regulatory body substance released in allergic reactions, causing swelling and inflammation of tissues; seen in hay fever and urticaria
anti-inflammatory
a drug that reduces inflammation
decongestant
a drug that reduces congestion and swelling of membranes, such as those of the nose and eustachian tube in an infection
