Otitis media

2

When is the highest incidence of Otitis media?

6-18 months old

3

Breastfeeding decreases the likelihood of what?

Otitis media

4

Why increased risk of Otitis media in winter/spring?

It's the cold/flu season so respiratory infections

5

What type of epithelium makes up respiratory epithelium?

Pseudo stratified ciliated columnar epithelium with goblet cells.

6

What 3 functions does the Eustachian tube perform?

1) Protection
2) Drainage
3) Ventilation

7

What is the difference in angle between Eustachian tube between adults and infants?

Adults have an angle of 45 degrees while infants have angle of 10 degrees

8

What causes the inflammation that precedes Otitis media

Allergies and URI

9

What does inflammation cause in the pathogenesis of OM?

Eustachian tube blocking

10

What blocks the Eustachian tube?

Masses, smoke, and anatomy

11

After the Eustachian tube is blocked what happens?

Middle ear effusion/barotrauma from pressure differences

12

Middle ear effusion leads to what?

Nasopharyngeal contamination

13

What happens after nasopharyngeal contamination?

Acute otitis media/Otitis media with effusion

14

Can you catch otitis media?

No, but you can catch the respiratory infection that caused the OM.

15

3 big bacteria that can cause OM?

1) Strep. Pneumoniae
2) H. Influenzae
3) Moraxella catarhallis

16

Most clinically significant identifier of AOM?

Pain

17

Facial paralysis is indicative of what?

Bell's palsy

18

Mastoiditis or lymphadenitis

19

What can cause vertigo, nystagmus, and tinnitus?

Esutachian tube dysfunction, labyrinthitis

20

What is Ramsay Hunt?

Varicella Zoster (Chicken Pox)

21

What is the AOM Tympanic Membrane triad?

1) Bulging
2) Immobile
3) Red

22

Pneumococcal infection

23

Otitis conjunctiva syndrome indicates what?

H. influenzae

In what quadrant do we see the light reflex on TM?

Anteroinferior

27

Where does tuning fork go for Weber test?

Forehead

28

What does a normal Weber test show?

No lateralization

29

What happens in unilateral hearing loss during Weber test?

Sound lateralizes toward affected ear

30

What happens during sensorineural loss in Weber test?

Sound lateralizes to normal hearing ear

31

Where does tuning fork go for Rinne test?

Mastoid bone

32

What shows up in an abnormal Rinne test?

Bone conduction > air conduction

33

How do you treat the symptoms of AOM?

Topical anesthetic, analgesics, and local heat

34

Antimicrobial of choice for AOM?

Amoxicillin

35

Time course for AOM treatment?

About 10 days. Shorter if >2 yrs and no risk factors, should see response in 1-2 days

36

How do you treat for recurrent OM?

Prophylaxis of amoxicillin or sulfisoxamole

37

What should you keep an eye on during recurrent OM?

Hearing, speech, and language

38

Purpose of an adenoidectomy?

Remove potential for blockage of eustachian tube

39

Why is bilateral effusion a real problem?

They can't hear and it can cause developmental delays
