MT CH 13 Symptomatic and Diagnostic Terms (EAR) Flashcards
otalgia or otodynia
earache
otorrhagia
bleeding from the ear
otorrhea
purulent drainage from the ear
tinnitus
a jingling; ringing or buzzing in the ear
vertigo
a turning round; dizziness
EXTERNAL EAR DIAGNOSTIC:
EXTERNAL EAR DIAGNOSTIC:
otitis externa
inflammation of the external auditory meatus (canal)
cerumen impaction
excessive buildup of wax in the ear
MIDDLE EAR DIAGNOSTIC:
MIDDLE EAR DIAGNOSTIC:
myringitis or tympanitis
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
otosclerosis
hardening of the bony tissue in the ear
mastoiditis
inflammation of the mastoid process; most commonly seen as a result of the spread of inflammation and infection in otitis media
eustachian obstruction
blockage of the eustachian tube usually as a result of infection, as in otitis media
INNER EAR DIAGNOSTIC:
INNER EAR DIAGNOSTIC:
acoustic neuroma
benign tumor on the auditory nerve (8th cranial nerve) that causes vertigo, tinnitus, and hearing loss
aplasia
condition of absence or malformation of inner ear structures during embryonic development, resulting in hearing loss
labyrinthitis
inflammation of the labyrinth
Meniere disease
disorder of the inner ear due to an excessive buildup of endolymphatic fluid causing episodes of vertigo, tinnitus, nausea, vomiting, and hearing loss; one or both ears can be affected, and attacks vary in frequency and intensity
GENERAL DIAGNOSIS:
GENERAL DIAGNOSIS:
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 or dysfunction of the cochlea or auditory nerve
mixed hearing loss
combination of sensorineural and conductive hearing loss
presbyacusis or presbycusis
hearing impairment in old age
DIAGNOSTIC TESTS AND PROCEDURES:
DIAGNOSTIC TESTS AND PROCEDURES:
audiometry
process of measuring hearing
audiometer
instrument to measure hearing
audiogram
record of hearing measurement
audiologist
person 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, fork-like instrument that vibrates when struck; used to test for hearing, especially bone conduction
brainstem auditory evoked potentials (BAEP)
electrodiagnostic testing using computerized equipment to measure involuntary responses to sound within the auditory nervous system - commonly used to assess hearing in newborns
otoscopy
use of an otoscope to examine the external auditory meatus (canal) and tympanic membrane
pneumatic otoscopy
otoscopic observation of the tympanic membrane as air is released into the external auditory meatus (canal); immobility indicates the presence of middle ear effusion (fluid buildup) as occurs as a result of otitis media
tympanometry
measurement of the compliance and mobility (conductibility) of the tympanic membrane and ossicles of the middle ear by monitoring the response after exposure to external airflow pressures
