-
Audiometry
(3 Types)
- process of measuring the heart
- - 3 types: audiometer, audiogram, audiologist
-
Audiometer
- audiometry
- -
instrument to measure hearing
-
Audiogram
- audiometry
- -
record of hearing measurment
-
Audiologist
- audiometry
- -
person who specializes in the study of hearing impairments
-
Auditory Acuity Testing
- - physical assessment of hearing
- - useful in differentiating between conductive & sensorineural hearing loss
- - tuning fork
-
Tuning Fork
- two-pronged fork-like instrument that vibrates when struck
- - used for: testing hearing (especially bone conduction)
-
Brainstem Auditory Evoked Potentials (BAEP)
electrodiagnostic testing using computerized equipment to measure involuntary responses to sound within the auditory nervous meatus (canal) & tympanic membrane
-
Otoscopy
use of an otoscpoe to examine the external auditory meatus (canal) & 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 & mobility (conductibility) of the tympanic membrane & ossicles of the middle ear by monitoring the response after exposure to external airflow pressures
-
Microsurgery
- operative
- -
surgery with the use of a microscope - - used in procedure involving delicate tissue such as the ear
-
Myringotomy
(Tympanostomy)
- operative
- - incision into the eardrum, most often for the insertion of a small metal or plastic tube (polyethylene tube- PE), to keep the meatus (canal) open
- - avoids fluid buildup (effusion) as that which occurs as a result of otitis media
-
Otoplasty
- operative
- -
surgical repair of the external ear
-
Stapedectomy
- operative
- - excison
of the stapes
-
Tympanoplasty
- operative
- - vein graft
of a scarred tympanic membrane - - improves sound conduction
-
Auditory Prosthesis
(2 types)
- therapeutic
- -
any internal or external device that improves or substitutes for natural hearing - - 2 types: hearing aid, cochlear implant
-
Hearing Aid
- therapeutic (auditory prosthesis)
- - external amplifying device
designed to improve hearing by more effective collection of sound into the ear
-
Cochlear Implant
- therapeutic (auditory prosthesis)
- -
electronic device implanted in the cochlea- provides sound perception to patients with severe or profound sensorineural (nerve) hearing loss in both ears
-
Ear Lavage
- therapeutic
- - irrigation
of the external ear canal - - common use: removal of excessive buildup of cerumen
-
Antibiotics
- therapeutic drug
- -
drug that inhibits growth or destroys microorganisms - - use: treatment of diseases that cause bacteria (otitis media)
-
Antihistamine
- therapeutic drug
- -
blocks the effects of histamine
-
Histamine
regulating body substance released in excess during allergic reactions that cause swelling & inflammation of tissues
-
Anti-Inflammatory
- therapeutic drug
- -
reduces inflammation
-
Decongestant
- therapeutic drug
- -
reduces congestion & swelling of membranes, such as those of the nose & eustachian tube after infection
-
BAEP
brainstem auditory evoked potentials
-
