Week 4: Tympanic Membrane Disorders/Diseases

Question 1

What type of hearing loss a tympanic membrane disease may cause?

Answer 1

conductive hearing loss

Question 2

In terms of Conductive hearing loss, what is the difference between SRT and PTA?

Answer 2

no more than 6 dB

Question 3

In terms of Conductive hearing loss, what is the accordance/agreement between SRT and PTA?

Answer 3

GOOD

Question 4

In terms of Conductive hearing loss, state the WRS percentage

Answer 4

96 to 100%

Question 5

What are the tympanic membrane disorders/diseases discussed in class?

Answer 5

Myringitis
Tympanosclerosis
Tympanic Membrane Perforation
Atrophic Tympanic Membrane

Question 6

What is Myringitis?

Answer 6

an infectious disease of the tympanic membrane caused by a virus or bacteria

Question 7

What does myringitis may cause the patient?

Answer 7

painful blisters or vesicles on the eardrum

Audiometry: Conductive hearing loss

Question 8

What can not be done to a patient who suffers myringitis? Why?

Answer 8

hearing testing may not be completed due to client discomfort or pain

Question 9

What is Tympanosclerosis?

Answer 9

calcium plaques on the surfaces of the tympanic membrane

Question 10

Tympanosclerosis may appear in response to what?

Answer 10

chronic (persistent, long term) infection of the middle ear
after a direct trauma of the tympanic membrane
after a tympanostomy tube (ear ventilation tube)

Question 11

Describes the result of the hearing assessment done to a patient who suffers from Tympanosclerosis (Audiometry, ECV)

Answer 11

Audiometry: audiogram WNL or slight Conductive hearing loss
ECV: normal

Question 12

What is Tympanic Membrane Perforation?

Answer 12

ruptured membrane

Question 13

The tympanic membrane may become perforated in response to what?

Answer 13

direct trauma (hairpin, etc.)
pressure in the external ear canal (explosion, a hand clapped over the ear)
infection (usually in the middle ear)
excessive pressure build-up (diving)

Question 14

Describes the result of the hearing assessment done to a patient who suffers from Tympanic Membrane Perforation (Audiometry, Speech Audiometry, Tympanometry, ECV)

Answer 14

Audiometry: Conductive hearing loss (varying degrees and based upon the size and location of the perforation)
Speech Audiometry: SRT and PTA are at 0 - 6 dB of each other, the accordance between SRT and PTA is GOOD, WRS is 100 to 96%
Tympanometry: Type B
ECV: large

Question 15

What is Atrophic Tympanic Membrane?

Answer 15

a very thin and flaccid tympanic membrane that is hypermobile (presents a high/increased compliance) and very translucent - the atrophy may be diffused or localized
the middle layer of the tympanic membrane is very thin

Question 16

Describes the result of the hearing assessment done to a patient who suffers from Atrophic Tympanic Membrane (Audiometry, Tympanometry ECV)

Answer 16

Audiometry: WNL (even though the tympanic membrane is atrophic, the thinning had no effect on the conduction of sound)
Tympanometry: Type Ad
ECV: normal

Question 17

True or False. Many disorders of the tympanic membrane do not require medical or surgical intervention (treatment)

Answer 17

false

many disorders of the tympanic membrane do require medical or surgical intervention (treatment)

Question 18

True or False. Medical Referrals is critical

Answer 18

true
medical referrals (red flags) is critical

Question 19

What are the infections related to the tympanic membrane?

Answer 19

myringitis

tympanic membrane perforation

Question 20

What are the infections related to the middle ear?

Answer 20

acute otitis media

Question 21

Disorders/diseases that cause Conductive hearing loss

Answer 21

atelectasis
otitis media with effusion
ossicular chain disarticulation
otosclerosis
cholesteatoma

Question 22

Disorders/diseases that cause Mixed hearing loss

Answer 22

otosclerosis, cholesteatoma
