Q

Tx of choanal atresia

A

•Dependent upon severity
•Unilateral can be monitored if no respiratory distress or feeding issues. Nasal salinerinses.
•Bilateral must be treated as soon as possible. Surgical repair to open nasal
airway sufficiently to allow the infant to breathe on their own.

Smoking and excessive alcohol consumption

80
Q

What increases the risk of esophageal SCC?

A

The presence of specific preexisting esophageal diseases (such as achalasia, Barrett’s esophagus and caustic strictures)

81
Q

82

Cancer staging is based on ?

A

location and size of tumor, adjacent tissue involvement, nodal involvement

83
Q

Cancer staging: T

A

describes the size of the original (primary) tumor and whether it has invaded nearby tissue

84
Q

Cancer staging: N

A

describes nearby (regional) lymph nodes that are involved

85
Q

Cancer staging: M

A

describes distant metastases (spread of cancer from one part of the body another)

86
Q
