Medical Terminology OFT 140

• process of measuring the heart
• - 3 types: audiometer, audiogram, audiologist

• audiometry
• - instrument to measure hearing

• audiometry
• - record of hearing measurment

• audiometry
• - person who specializes in the study of hearing impairments

• - physical assessment of hearing
• - useful in differentiating between conductive & sensorineural hearing loss
• - tuning fork

• two-pronged fork-like instrument that vibrates when struck
• - used for: testing hearing (especially bone conduction)

electrodiagnostic testing using computerized equipment to measure involuntary responses to sound within the auditory nervous meatus (canal) & tympanic membrane

use of an otoscpoe to examine the external auditory meatus (canal) & tympanic membrane

• 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

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

• operative
• - surgery with the use of a microscope
• - used in procedure involving delicate tissue such as the ear

• 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

• operative
• - surgical repair of the external ear

• operative
• - excison of the stapes
• - corrects: otosclerosis

• operative
• - vein graft of a scarred tympanic membrane
• - improves sound conduction

• therapeutic
• - any internal or external device that improves or substitutes for natural hearing
• - 2 types: hearing aid, cochlear implant

• therapeutic (auditory prosthesis)
• - external amplifying device designed to improve hearing by more effective collection of sound into the ear

• 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

• therapeutic
• - irrigation of the external ear canal
• - common use: removal of excessive buildup of cerumen

• therapeutic drug
• - drug that inhibits growth or destroys microorganisms
• - use: treatment of diseases that cause bacteria (otitis media)

• therapeutic drug
• - blocks the effects of histamine

regulating body substance released in excess during allergic reactions that cause swelling & inflammation of tissues

• therapeutic drug
• - reduces inflammation

• therapeutic drug
• - reduces congestion & swelling of membranes, such as those of the nose & eustachian tube after infection
