Question 1

What is an otoscopy.

Answer 1

an examination of the structures of the ear, particularly the external auditory canal, tympanic membrane, and middle ear. Clinicians use the process to evaluate specific ear complaints.

Question 2

When might an otoscopy be used

Answer 2

during regular check-ups and also to investigate ear symptoms.

Question 3

What diseases can an otoscope help diagnose

Answer 3

• Acute otitis media
• Otitis media with effusion
• Chronic suppurative otitis media

Question 4

What is a pure-tone audiometry test

Answer 4

A test used to identify hearing threshold levels of an individual, enabling determination of the degree and type and configuration of a hearing loss.

Question 5

When might a pure tone audiometry test be used

Answer 5

to determine how well someone can hear. May be done as part of a routine check-up or in response to a noticeable loss of hearing.

Question 6

What diseases can a pure tone audiometry test help diagnose.

Answer 6

sensorineural hearing loss (damage to the nerve or cochlea) or conductive hearing loss (damage to the eardrum or the tiny ossicular bones).

Question 7

What is a tympanometry

Answer 7

evaluate the condition of the middle ear eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal. Tympanometry is an objective test of middle-ear function.

Question 8

When may an tympanometry exam be used

Answer 8

Often used to assess the function of the middle ear, tympanometry is one test that can determine whether your hearing loss can be helped by hearing aids or whether a medical treatment is available to treat your loss instead.

Question 9

What diseases can tympanometry help diagnose

Answer 9

• fluid in the middle ear
• perforation of the eardrum (tympanic membrane)
• scarring of the eardrum, which usually results from - - - frequent ear infections
• middle ear pressure beyond the normal range
• growths in the middle ear
• earwax blocking the eardrum

Question 10

What is a tuning fork test

Answer 10

is a screening test for hearing performed with a tuning fork. It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss).

Question 11

When may a tuning fork test be used

Answer 11

may be used as part of a check up, however can be used to look into specific ear symptoms.

Question 12

What disease may a tuning fork test diagnose

Answer 12

can detect unilateral conductive and sensorineural hearing loss. The outer and middle ear mediate conductive hearing. The inner ear mediates sensorineural hearing

Question 13

What is a nerve conduction studies exam

Answer 13

measures how fast an electrical impulse moves through your nerve. Can identify nerve damage. During the test, your nerve is stimulated, usually with electrode patches attached to your skin.

Question 14

When might a nerve conduction studies test be used

Answer 14

Done to find and evaluate damage to all the nerves that lead away from the brain and spinal cord to the smaller nerves that branch out from them.

Question 15

What disease may a nerve conduction studies test diagnose

Answer 15

Help diagnose nerve disorders, such as carpal tunnel syndrome or Guillain-Barré syndrome.

Question 16

What is an electromyography

Answer 16

evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram.

Question 17

When might an electromyography be used

Answer 17

is used to help identify, evaluate and find nerve and muscle problems. During the test, your healthcare provider will put a small needle (also called electrodes) through your skin into a muscle.

Question 18

What disease can an electromyography test diagnose

Answer 18

• Amyotrophic lateral sclerosis (ALS)
• Carpal tunnel syndrome.
• Cervical spondylosis.
• Guillain-Barre syndrome.
• Lambert-Eaton syndrome.
• Muscular dystrophy.
• Myasthenia gravis.

Question 19

What is an Electroencephalography test

Answer 19

A test that records electrical activity of the brain. It is typically non-invasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used, as in electrocorticography, sometimes called intracranial EEG.

Question 20

When might an electroencephalography test be used

Answer 20

done to diagnose and monitor seizure disorders. EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior. They’re sometimes used to evaluate brain activity after a severe head injury or before a heart transplant or liver transplant.

Question 21

What diseases can a electroencephalography help diagnose

Answer 21

• Sleep disorders (such as narcolepsy)
• Head injuries.
• Brain infection.
• Brain haemorrhage.
• Alzheimer’s disease.
• Degeneration of brain tissue.

Question 22

What is an evoked potentials test

Answer 22

Is a electrical potential in a specific pattern recorded from a specific part of the nervous system, especially the brain, of a human or other animals following presentation of a stimulus such as a light flash or a pure tone.

Question 23

When might an evoked potentials test be used

Answer 23

test can diagnose hearing ability and can point to possible brainstem tumours or multiple sclerosis. A healthcare professional places electrodes on your scalp and earlobes and delivers auditory stimuli, such as clicking noises and tones, to one ear

Question 24

What diseases can an evoked potentials test diagnose.

Answer 24

Doctors use the test to help diagnose multiple sclerosis (MS) and other conditions that can cause a person’s reactions to slow. The test can detect unusual responses to stimulation.
