This procedure is done to visualize the upper airway and most commonly used to rule out vocal cord dysfunction. It involves the use of a small flexible fiberoptic scope inserted through the patient's anesthetized nasal passage. The laryngoscopy is often done following an exercise or bronchial provocation test.
Actual visualization lasts approximately two minutes. The procedure is recorded for the patient's medical record.
