auricle

external structure located on both sides of the head. This structure directs sound waves into the external auditory canal

external auditory canal

short tube that ends at the tympanic membrane. The inner part lies within the temporal bone of the skull and contains the glands that secrete earwax

tympanic membrane

semitransparent membrane that separates the external auditory canal and the middle ear cavity. The tympanic membrane transmits sound vibrations to the ossicles

eustachian tube

connects the middle ear and the pharynx. It equalizes air pressure on both sides of the eardrum

ossicles

bones of the middle ear that carry sounds vibrations. It is composed of the malleus, incus, and stapes. The stapes connects to the oval window, which transmits the sound vibrations to the cochlea of the inner ear

labyrinth

bony spaces within the temporal bone of the skull. It contains the cochlea, semicircular canals, and vestibule

cochlea

snail-shaped and contains the organ of hearing. The structure connects to the oval window in the middle ear

semicircular canals and vestibule

contains receptors and endolymph that help the body maintain its sense of balance (equilibrium)

mastoid bone and cells

located in the skull bone behind the external auditory canal

audi/o

hearing

aur/i, aur/o, ot/o

ear

cochle/o

cochlea

labyrinth/o

labyrinth (inner ear)

mastoid/o

mastoid bone

myring/o

tympanic membrane

staped/o

stapes

tympan/o

tympanic membrane (eardrum), middle ear

vestibul/o

vestibule

labyrinithitis

inflammation of the labyrinth

mastoiditis

inflammation of the mastoid

myringitis

inflammation of the tympanic membrane

otalgia

pain in the ear

otomastoiditis

inflammation of the ear and the mastoid bone

otomycosis

abnormal condition of fungus in the ear

otopyorrhea

discharge of pus from the ear

otorrhea

discharge from the ear

otosclerosis

hardening of the ear (stapes)

acoustic neuroma

benign tumor within the internal auditory canal growing from the acoustic nerve; may cause hearing loss and may damage structures of the cerebellum as it grows

ceruminoma

tumor of a gland that secretes earwax

cholesteatoma

cystlike mass composed of epithelial cells and cholesterol occurring in the middle ear; may be associated with chronic otitis media

Meniere Disease

chronic disease of the inner ear characterized by a sensation of spinning motion, ringing in the ear (tinnitus), aural fullness, and fluctuating hearing loss; symptoms are related to a change in volume or composition of fluid within the labyrinth

otitis externa

inflammation of the outer ear

otitis media

inflammation of the middle ear

presbycusis

hearing impairing in old age

tinnitus

ringing in the ear

vertigo

a sense that either one's own body or the environment is revolving; may indicate inner ear disease

cochlear implant

pertaining to the cochlea implant (surgically inserted prosthetic device that uses electrical currents to stimulate the auditory nerve and provide hearing)

labyrinthectomy

excision of the labyrinth

mastoidectomy

excision of the mastoid bone

mastoidotomy

incision into the mastoid bone

myringoplasty

surgical repair of the tympanic membrane

myringotomy

incision into the tympanic membrane

stapedectomy

excision of the stapes

tympanoplasty

surgical repair of the middle ear

audiogram

record of hearing

audiometer

instrument used to measure hearing

audiometry

measurement of hearing

electrocochleography

process of recording the electrical activity in the cochlea

otoscope

instrument used for visual examination of the ear

otoscopy

visual examination of the ear

tympanometer

instrument used to measure middle ear (functions)

tympanometry

measurement (of movement) of the tympanic membrane
