Q

How is chronic tonsillitis different than recurrent tonsillitis?

A

Chronic low-grade infection of the tonsils can occur in older children, adolescents, and adults. These patients often have large crypts, or spaces within the tonsils that collect food and debris (chronic halitosis), that are difficult to treat with antibiotics.

38
Q

What is the problem with aspiration of peanuts?

A

the oil and salt produce a chemical inflammation that causes the bronchial mucosa to swell, making removal difficult.

39
Q

Foreign body aspiration can cause bronchial ball valve obstruction which will hypo/hyperinflate one lung

A

Hyper

40
Q

Why is subglottic stenosis becoming more common cause of stridor?

A

NICU with long-term tube placement scars the endotracheal tube and eventionally the subglottic area.

41
Q

Is stridor biphasic or monophasic with subglottic stenosis?

A

Biphasic (same with croup - makes sense bc both subglottic but croup due to infection.

Q

Tx for severe subglottic stenosis? Mild?

A
  1. Tracheotomy (butmay delay speech and get plugged w/mucus)

  3. Mild - laser plus balloon dilation
43
Q

Sublgottic hemangiomas can cause stridor and occur at ___ age range. When will spontaneous involution occur?

Q

___% of pts w/subglottic hemangiomas have other associated head and neck hemangiomatas on skin

A

50

45
Q
