Hearing Loss and Auditory Disorders

Question 1

Congenital

Answer 1

condition that begins at birth

Question 2

Idiopathic

Answer 2

Cause can’t be identified.

Question 3

Impairment

Answer 3

A loss of structure or function. Example: fell down the stairs and hurt foot.

Question 4

Disability

Answer 4

Term that includes the impairment as well as the environmental factors that interfere with functioning. Inability to perform certain tasks because of impairment. Example: Can’t write due to impairment. Perceived by patient.

Question 5

Handicap

Answer 5

The functional consequences associated with a particular impairment. Example: Inability to write makes it so someone can’t fulfill their role as a note-taker. Perceived by patient.

Question 6

Conductive System

Answer 6

outer and middle ear

Question 7

Sensorineural System

Answer 7

Cochlea and Auditory Nerve

Question 8

Anotia

Answer 8

Absence of the pinna on one or both sides

Question 9

Microtia

Answer 9

A small, malformed pinna that does not result in loss of hearing sensitivity by itself.

Question 10

Atresia

Answer 10

Complete closure of the auditory canal; significant hearing loss is inevitable

Question 11

Otosclerosis

Answer 11

The replacement of healthy bone with spongy bone in the stapes footplate, resulting in reduced mobility of the stapes and hearing loss.

Question 12

Otitis media

Answer 12

inflammation of the mucous membrane lining in the middle ear cavity

Question 13

Myringotomy

Answer 13

Incision in eardrum to drain fluid in middle ear

Question 14

Pressure equalization or tympanostomy tubes

Answer 14

inserted into the eardrum and function as the Eustachian tube

Question 15

Aplasia/dysplasia

Answer 15

hearing loss due to absence or malformation of inner ear structures during embryonic development.

Question 16

Usher’s Syndrome

Answer 16

Genetic disorder characterized by sensorineural hearing loss and degenerative visual changes.

Question 17

Waardenburg’s Syndrome

Answer 17

Genetic disorder characterized by sensorineural hearing loss and changes in the coloring of the hair, skin, and eyes.

Question 18

Alport’s Syndrome

Answer 18

Marked by sensorineural hearing loss and kidney disease.

Question 19

Meningitis

Answer 19

Inflammation of the fluids and layers of tissue covering the brain.

Question 20

Meniere’s Disease

Answer 20

Fluctuating and progressive sensorineural hearing loss, tinnitus, vertigo, and a feeling of fullness in the ear. Symptoms typically come and go unpredictably.

Question 21

Auditory Neuropathy Spectrum Disorder

Answer 21

Normal outer hair cell function and abnormal responses from the inner hair cells or auditory nerve fibers. Characterized by a lack of synchrony in the firing of auditory nerve fibers with normal outer hair cell function.

Question 22

Vestibular schwannoma/acoustic neuroma

Answer 22

A non-malignant growth develops on the cells near cranial nerve VIII. Symptoms include decreased hearing, tinnitus, balance difficulty, and a plugged feeling on the affected side. Surgery is usually recommended.

Question 23

Temporary threshold shift

Answer 23

Hearing loss due to short-term noise exposure.

Question 24

Permanent Threshold Shift

Answer 24

Loss of high frequency sensitivity due to frequent exposure to high levels of noise.

Question 25

presbycusis

Answer 25

hearing loss that occurs through aging process

Question 26

Mixed Hearing Loss

Answer 26

Presence of both conductive and sensorineural hearing loss

Question 27

Bimodal Hearing

Answer 27

A cochlear implant is used on one ear and a hearing aid is used on the other.

Question 28

Hearing Assistive Technology

Answer 28

Assistive devices used to overcome problems hearing in various situations.

Question 29

FM System

Answer 29

The talker speaks into a microphone attached to a transmitter that broadcasts on a designated frequency or channel.

Question 30

Sound Field Amplification

Answer 30

Loudspeakers are used rather than a broadcast to one receiver.
