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

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

otomycosis
abnormal condition of fungus in the ear
otopyorrhea
discharge of pus from the ear
otorrhea
discharge from the ear
otosclerosis

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
