Bronchoscopy is a procedure that allows your
doctor to look at your airway through a thin viewing instrument called a
bronchoscope. During a bronchoscopy , your doctor will examine your throat,
trachea , and lower airways.

lymph nodes in the chest, or to treat problems such as
an object or growth in the airway.
There are two types of
- Flexible bronchoscopy
uses a long, thin, lighted tube to look at your airway. The flexible
bronchoscope is used more often than the rigid bronchoscope because it usually
does not require
general anesthesia, is more comfortable for the
person, and offers a better view of the smaller airways. It also allows the
doctor to remove small samples of tissue (biopsy).
- Rigid bronchoscopy is usually done with general anesthesia and uses a
straight, hollow metal tube. It is used:
- When there is bleeding in the airway that
could block the flexible scope's view.
- To remove large tissue
samples for biopsy.
- To clear the airway of objects (such as a piece
of food) that cannot be removed using a flexible bronchoscope.
Special procedures, such as widening (dilating) the airway
or destroying a growth using a
laser, are usually done with a rigid
