Otitis Media with Effusion Flashcards

1
Q

What is otitis media with effusion?

1 - otitis media with bacteria infection of middle ear
2 - otitis media with viral infection of middle ear
3 - otitis media with collection of fluid in middle ear but no signs of infection
4 - can be any of the above

A

3 - otitis media with collection of fluid in middle ear but no signs of infection

Tympanic membrane appears dull or grey

Acute otitis media can progress to chronic (>3months) otitis media with effusion also known as glue ear, less common than acute though

Q

Does otitis media with effusion lead to sensorineural or conductive hearing loss?

2 - history of conductive hearing loss
3 - aural pressure build up with popping sounds
4 - speech and language issues in children
5 - all of the above

A

Q

If an adults presents with unilateral otitis media with effusion, what must we do?

1 - monitor for 3 months
2 - monitor 3 days and then amoxicillin
3 - fast track ENT referral
4 - topical antibiotics

A

Q

In the image below from an audiogram, does this show conductive or sensorineural hearing loss in the right ear?

A
  • Conductive

The air does not conduct sound as it should

Can see a difference between the air and bone conduction

Q

In the image below from an audiogram, does this show conductive or sensorineural hearing loss in the right ear?

A
  • Sensorineural

Typically affects higher frequencies more

Begins normal on audiogram and then it drops

Both air and bone conduction affected

2 - prescribe amoxicillin
3 - reassure and sefty net
4 - routine referral

Q

Acute otitis media can progress to acute otitis media with effusion, which is otitis media with collection of fluid in middle ear. This is typically treated conservatively using auto inflation with a balloon. What is the purpose of this?

1 - steroid spray delivered up the nose via balloon
2 - dooching of the nose using balloon
3 - valsalva manoeuvre that equalises ear pressure
4 - all of the above

A

3 - valsalva manoeuvre that equalises ear pressure

Can consider hearing aids

2 - parents request
3 - antibiotics have no effect >3 months
4 - steroid and antibiotic ineffective

Q

Otitis media with effusion (OME) is when there is a fluid collection in the middle ear. Does there have to be signs of an infection in OME?

A
  • No

Often called Glue ear

This is the distinguishing factor between otitis media and OME

17
Q

Some patients with otitis media can deteriorate despite antibiotics. All of the following should be admitted to hospital, EXCEPT which one?

1 - severe systemic infection
2 - acute complications (meningitis, mastoiditis, facial nerve palsy)
3 - develop otitis media with effusion
4 - child <3 months with temp >38
5 - child 3-6 months with temp >39

A

3 - develop otitis media with effusion
