Otology Flashcards
ossicles
bones of the middle ear that carry sound vibrations.
labyrinth (inner ear)
bony spaces within the temporal bone of the skull. It contains the cochlea, semicircular canals, and vestibule.
cochle/o
cochlea
eustachian tube
connects the middle ear and the pharynx.
semicircular canals and vestibule
contains receptors and endolymph that help the body maintain its sense of balance
aur/i, aur/o, ot/o
ear
external ear auricle (pinna)
external structure located on both sides of the head. The auricle directs sound waves into the external auditory canal.
audi/o
hearing
otomastoiditis (o-to-mas-toyd-I-tis)
inflammation of the ear and the mastoid bone
labyrinthitis (lab-i-rin-THI-tis)
inflammation of the labyrinth (inner ear, also called vestibular neuritis)
mastoiditis (mas-toyd-I-tis)
inflammation of the mastoid bone
myringitis (mir-in-JI-tis)
inflammation of the tympanic membrane (eardrum)
cochlea
is snail-shaped and contains the organ of hearing. The cochlea connects to the oval window in the middle ear.
labyrinth/o
labyrinth (inner ear)
mastoid boane and cells
located in the skull bone behind the external auditory canal
mastoid/o
mastoid bone
otalgia (o-TAL-ja)
pain in the ear
tympanic membrane (eardrum)
semitransparent membrane that seperates the external auditory canal and the middle ear cavity. It transmitts sound vibrationsto the ossicles
external auditory canal (meatus)
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
staped/o
stapes (middle ear bone)
myring/o
tympanic membrane (eardrum)
tympan/o
tympanic membrane (eardrum), middle ear

vestibule

ceruminome (se-roo-mi-NO-ma)
tumor of a gland that secretes earwax
cholesteatoma (ko-le-ste-a-TO-ma)
cystlike mass composed of epithelial cells and cholesterol occuring in the middle ear, may be associated with chronic otitis media
Meniere disease (me-NYAR di-ZEZ)
chronic disease of the inner ear characterizid by a sensation of spinning motion (vertigo), ringing in the ear, aural fullness, and fluctuating hearing loss; symptoms are related to a change in volume or composition of fluid withing the labyrinth
otitis externa (o-TI-tis eks-TER-na)
inflammation of the outer ear
otitis media (OM)
inflammation of the middle ear (also called tympanitis)
presbycusis (prez-bi-KU-sis)
hearing impairment in old age
tinnitus (tin-NI-tus)
ringing in the ear
vertigo (VER-ti-go)
a sense that either ones own body or the enviroment is revolving ; may indicate inner ear disease

myringotomy (mir-ing-GOT-o-me)
incision into the tympanic membrane (also called tympanocentesis)
stapedectomy (sta-pe-DEK-to-me)
excision of the stapes
tympanoplasty (TIM-pa-no-plas-te)
