Flashcards in Lecture 17 Otitis Media Deck (23):
1

What is the most common diagnosis made in sick children in the US?

otitis media (OM)

2

What time of year is OM most prevalent?

winter/early spring

3

what kind of epithelium is seen in the eustachian tube and middle ear?

respiratory epithelium
ie pseudostratified ciliated columnar epithelium with goblet cells

4

Is the eustachian tube at a steeper or shallower angle in kids relative to adults? Why does this matter?

shallower --> less drainage, so more risk of infection

5

What is OME?

otitis media effusion;
chronic, non-infectious form of OM

6

Besides virsuses, what are the 3 most common causes of OM?

strep pneumo, H-flu, moraxella catarhallis

7

"popping ears" pulls on the ____ muscle, opening the eustachian tube

tensor veli palatini

8

what sort of infection is OM often a sequelae of ?

upper respiratory infection

9

what should you save for the last part of the physical exam in patients with OM?

throat (kids aren't fans of tongue depressors)

10

Acute OM tympanic membrane (TM) triad of symptoms:

bulging, immobile, red

11

what should you suspect if a patient presents with fever and ear ache?

strep pneumo

12

what should you suspect if a patient presents with TM perforation or mastoiditis?

group A strep

13

What should you suspect if a patient presents with OM and conjunctivitis or bilateral OM?

H-flu

14

normal TM is described as having what color?

pearly gray

15

a swollen external auditory meatus is indicative of what?

acute otitis externa (eg swimmer's ear)

16

when there is ____ pressure in the middle ear cavity, the TM is retracted (ie chronic OME)

negative

17

drug of choice for treating Acute OM?

amoxicillin

18

most common complication of OM

hearing loss

19

_____ is characterized by dense calcification and excessive scarring and fibrosis of the TM

Tympanosclerosis

20

chronic purulent drainage, white mass behind the ear drum --> indicative of _____

cholesteatoma

21

what do tympanograms measure?

middle-ear pressure

22

Deep tymanograms are characteristic of _____ compliance, such as in ossicular chain discontinuity

increased

23

shallow tympanograms show decreased compliance, suggesting a stiff middle ear system. What might cause this finding?

tympanosclerosis
