Represents a spectrum of disorders involving an impairment in the functional valve of the eustachian tube of the middle ear

A

Eustachian Tube Dysfunction (ETD)

27

30
Q

Treatment for:

ETD

Fluticasone propionate (Flonase)

Cetirizine (Zyrtec)

Fexofenadine (Allegra)

31
Q

ETD:

Chronic cases, monitor pressure equalization tubes every:

A

6 to 12 months

32
Q

Occur secondary to middle ear infections or as a result of barotrauma, blunt/penetrating/acoustic trauma, or lightning strikes

A

33
Q

When perforation is secondary to blunt or noise trauma, the perforation almost always occurs in the:

A

A

TM Perforation

35
Q

Treatment of:

TM Perforation

39
Q

Treatment for:

Cholesteatoma

41
Q

Most common etiology of barotrauma

A

Flying

42
Q
