- pneumatic otoscopy
- otoscropic observation of the tympanic membrane as air is released into external auditory meatus (canal) immobility indicates the presence of middle ear effusion (fluid buildup) as occurs as result of otitis media
- audiometer
- instrument to meausre hearing
- tympanoplasty
- vein graft of scarred tympanic membrane to improve sound conduction
- decongestant
- drug that reduces congestion and swelling of membranes such as those of nose and eustachian tube after infection
- microsurgery
- surgery with use of microscope; delicate tissue
- audiometry
- process of measuring hearing
- histmaine
- allergic reactions - flammation of tissue; hay fever, urticaria (hives)
- auditory prosthesis
- any internal or external device that improves or sbstitutes for natural hearing
- audiogram
- record of hearing measurement
- cochlear implant
- electronic device implanted in the cochlea that provides sound perception to patients with severe or profound sensorineural (nerve) hearing loss in both ears
- tympanometry
- measurement of compliance and mobility (conductibility) of tympanic membrane and ossicles of middle ear by monitoring response after exposure to external airflow pressures
- audiologist
- person who specializes in study of hearing impariments
- otoscopy
- use of otoscope to examine the external auditory meatus (canal) and tympanic membrane
- otoplasty
- surgicla repair of external ear
- tuning fork
- two-pronged. fork-liked instrument that vibrates when struck; used to test for hearing; espcially bone conduction
- ear instillation
- introduction of medicated solution into external canal
- hearing aid
- external amplifying device designed to improve hearing by more effective collection of sound into the ear
- stapedectomy
- excision of stapes to correct otosclerosis
- myringotomoy, tympanostomy
- incision into eardrum, most often for inservtion of small metal or plastic tube (polyethylene tube) to keep meatus (canal) open, avoiding fluid buildup (effusion) as that which occurs as result of otitis media
- ear lavage
- irrigation of external ear canal, commonly done to remove excessive buildup of cerumen
- auditory acuity testing
- physical assessment of hearing; useful in differentiating between conductive and sensorineural hearing loss
- 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
- antibiotic
- treats otitis media
