-osis

abnormal condition (means increase when used with blood cell word roots)

-metry

labyrinthitis

inflammation of the labyrinth

myringitis

inflammation of the tympanic membrane (eardrum)

otalgia

pain in the ear

otomycosis

abnormal condition of fungus in the ear (usually affects the external auditory canal)

otopyorrhea

discharge of pus from the ear

otosclerosis

hardening of the ear (stapes) (caused by irregular bone development and resulting in hearing loss)

cholesteatoma

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

Ménière disease

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

otitis media (OM)

inflammation of the middle ear

ototoxicity

adverse pharmacologic reaction causing damage to the vestibulocochlear nerve; results in abnormalities of hearing and balance

presbycusis

hearing impairment occurring either age

tinnitus

ringing in the ears

vertigo

sense that either ones own body (subjective) or the environment (objective) is revolving; may indicate inner ear disease

cochlear implant

pertaining to the cochlea implant (surgically inserted electronic device that converts sound into electrical impulses. the impulses stimulate the auditory nerve to carry the signal to the brain, which learns to interpret the signal as sound. the damaged part of the ear is bypassed

myringotomy

incision into the tympanic membrane (performed to relieve pressure in the middle ear by releasing pus or fluid and for the placement of tubes)

otoplasty

surgical repair of the (outer) ear

stapedectomy

excision of the stapes (performed to restore hearing in cases of octosclerosis; the stapes is replaced by a prosthesis)

tympanostomy

creation of an artificial opening into the middle ear

audiogram

(graphic) record of hearing

audiometer

instrument used to measure hearing

electrocochleography

process of recording the electrical activity in the cochlea (in response to sound)

otoscopy

visual examination of the ear

tympanometry

measurement of the middle ear (function)

otolaryngologist (ENT)

physician who studies and treats diseases of the ear, (nose), and larynx (throat); (aka otorhinolaryngologist)

aural

pertaining to the ear

vestibucochlear

pertaining to the vestibule and the cochlea

AOM

acute otitis media

OE

otitis externa

OM

otitis media

HOH

hard of hearing
