How is a bronchoscopy performed?
This is a diagnostic procedure in which the throat, larynx, trachea, and lower airways are examined using a viewing instrument called a bronchoscope which is inserted through the nose or mouth. A flexible bronchoscope is a long, lighted tube which gives a view of the upper airways but also allows tissue biopsy. A rigid bronchoscope usually requires general anesthesia and uses a straight metal tube. This may be used when there is bleeding or obstruction in the airway or if a larger tissue sample is needed. Bronchoscopy will look for abnormal areas and identify the cause of any airway problems, and it may also take tissue samples for lab analysis.
