1
Q

A
Otitis media
2
Q
TQ What is the difference between acute otitis media (AOM) and otitis media with effusion (serous) (OME)?
A
- Acute otitis media=acute infx
- Otitis media w/ effusion is inflam of the middle ear w/ fluid, NO S/S of acute infx…is residual after AOM or due to dys from URI OME predisposes to AOM
3
Q
- Liquid in the middle ear
- Just a symptom! no path/pathology etc
- Fluid may–>conductive hearing loss: short term, 25% can have for 3 mos+
A
MEE (middle ear effusion) component of both AOM and OME
4

A
True
5
Q
TQ
What are some environmental causes of OM?
A

- Daycares (sick for 18-24 mo)
- Congenital anomalies (clefts, downs)
Other Factors:

A
OME
14
Q
TQ
What is a “pneumatic otoscopy”?
A
- exam that determines mobility of TM in response to pressure changes…impt in dx of AOM
- normally moves in response to pressure (inward w/ pos, outward w/ neg)
- *Immobile TM=MEE*
15
Q
TQ
T/F You can diagnose AOM without a middle ear effusion (based on pneumatic otoscopy +/- tympanometry)
A
FALSE
MUST do a pneumatic otoscopy + Bulging of TM
OR
New onset otorrhea not due to AOE
OR
Bulging of TM AND recent (<48 hrs) onset ear pain OR intense erythema of TM
16
Q
When treating OM it is impt to be prompt, because this may prevent development of complications such as…
A

17
Q
Tx of OM?
In addition to..
- Topical pain relief (if TM intact)
- Oral pain meds (IBUPROFEN, acetaminophen + Hydrocodone (Lortab))
A

A
- Infants: Outer 2/3 of the ear canal cartilaginous, inner 1/3 is bony
- Older child and adult: Outer 1/3 is cartilaginous.
The epithelium is thinner in the bony portion, without subcutaneous tissue (less room for swelling)
20

6) Leads to air trapping and overinflation
7) If complete obstruction, trapped distal air\>\>atelectasis
8) ???????????
9) Severe obstructive disease and tiring of effort, hypercapnia can result 
1) Virus-induced necrosis of bronchiolar epithelium
2) Hypersecretion of mucus
3) Round cell infiltration and edema of submucosa\>\>mucus plugs that obstruct bronchioles
4) Bronchiolar wall thickening ( a two-fold decrease in diameter leads to an 16 fold increase in resistance!!! (R=1/r4))
5) Respiratory obstruction results
6) Leads to air trapping and overinflation
7) If complete obstruction, trapped distal air\>\>atelectasis
8) Ventilation-perfusion mismatch can occur, and hypoxemia develops (perfused w/o ventil)
9) Severe obstructive disease and tiring of effort, hypercapnia can result 
46
