Ear Tests And Disorders

Front 1

Otoscopy

Back 1

direct visualization of the auditory canal and the tympanic membrane through an otoscope

Front 2

Weber's test

Back 2

Test using a tuning fork to evaluate bone conduction. The fork is placed in the center of the head to see which ear is affected

Front 3

Rinne Test

Back 3

Test using a tuning fork that compares bone conduction to air conduction in both ears. The fork touches the mastoid process with the prongs near the external ear

Front 4

Audiometry

Back 4

evaluation of hearing using an audiometer (measures tones at various frequencies)

Front 5

Hearing Loss or deafness

Back 5

a malfunction in the mechanical or nervous system that interrupts the transmission of sound waves

Front 6

Conducive Hearing Loss

Back 6

interrupted transmission of sound impulses from the external ear to the junction of the stapes and oval window

Front 7

Mixed Hearing Loss

Back 7

combined conductive and sensorineural dysfunctions

Front 8

Otosclerosis

Back 8

Slow growth of a spongy bone in the optic capsule, especially at the oval window (most common cause of progressive hearing loss)

Front 9

Sensorineural Loss

Back 9

impaired cochlear or acoustic nerve function that prevents transmission of sound impulses within the inner ear or brain

Front 10

Presbycusis

Back 10

Result of aging with the loss of hair cells in the organ of Corti (causes sensorineural loss, usually of high frequency tones)

Front 11

Infectious Myringitis

Back 11

inflammation, hemmorhage, and effusion of fluid into the tissue and at the end of the external ear canal and tympanic membrane

Front 12

Labyrinthitis

Back 12

inflammation of the labyrinth, frequently causing vertigo

Front 13

Mastoiditis

Back 13

bacterial infection and inflammation of the mastoid antrum air cells that is often a complication of chronic or acute otitis media

Front 14

Meniere's disease or
endolymphatic hydrops

Back 14

a labyrinthine dysfunction known to cause violent attacks of severe vertigo lasting from 10 minutes to several hours

Front 15

Otitis Externa

Back 15

inflammation of the external ear canal, which may be acute or chronic

Front 16

Otitis Media

Back 16

inflammation of the middle ear

Front 17

Acetic Acid or
Domeboro's Solution

Back 17

a preparation that treats ear canal infections and prevents "swimmers ear"

Front 18

Anesthetics

Back 18

drugs that treat pain from otitis media and assists with the removal of cerumen

Front 19

Antibiotics

Back 19

treat external ear canal infections

Front 20

Cerumeolytics

Back 20

help remove impacted cerumen

Front 21

Corticosteroids

Back 21

treats inflammation of the external ear canal (hydrocortisone)

Front 22

Myringotomy

Back 22

surgical incision into the tympanic membrane to relieve pain and drain pus or fluid from the middle ear

Front 23

Myringoplasty

Back 23

repairs a ruptured tympanic membrane

Front 24

Stapedectomy

Back 24

removes all or part of the stapes

Front 25

Total Stapedectomy

Back 25

removal of the entire bone, followed by insertion of a graft and prosthesis to bridge the gap between the incus and the inner ear

Front 26

Partial Stapedectomy

Back 26

part of the stapes bone is removed and a prosthesis replaces it

Front 27

Laser Stapedectomy

Back 27

easier than the traditional and carries a risk of penetrating the bone
